Empowering Digital Healthcare Transformation with ZIFTM

Posted on by Subhadeep Datta

The Modern-Day Healthcare

The healthcare industry is one of the biggest revenue generation sectors for the economy. In 2020, the healthcare industry generated close to $2.5 trillion dollars in the US. This has been made possible due to multiple revenue generation streams that encompass the development and commercialization of products and services that aid in maintaining and restoring health.

The modern healthcare industry has three essential sectors – services, products, and finance, which in turn can be further branched to various interdisciplinary groups of professionals that meet the health needs of their respective customers.

For any industry to scale and cover more customers, being digital is the best solution. Stepping into the digital space brings various tools and functionalities that can improve the effectivity and efficiency of the products and services offered in the Healthcare Industry.

The key component of any Digital Healthcare Transformation is it’s Patient-Focused Healthcare Approach. The transformation must aid healthcare providers in better streamlining the operations, understanding what the patients need and in turn build loyalty, trust and a stellar user experience.

Healthcare Transformation Trends

Innovation is the foundation for all Transformation initiatives. The vision of rationalizing work, optimizing systems, improving delivery results, eliminating human error, reducing costs, and improving the overall customer experiences are the levers that churn the wheel. With the advent of VR, wearable medical devices, telemedicine, and 5G using AI-enabled systems have significantly changed the traditional way that consumers use healthcare products and services.

The industry has shifted its focus in making intelligent and scalable systems that can process complex functionalities as well as deliver customer experience at its finest.  With the integration of AI and omnichannel platforms, organizations can better understand their customers, address service and product gaps to better capitalize the market to achieve higher growth. Hence, transformation is the key to pushing forward in unprecedented and unpredictable times in order to achieve organizational vision and goals.

Sacrosanct System Reliability

The healthcare industry is a very sensitive sector that requires careful attention to its customers. A mishap in the service can result in a life-and-death situation. Healthcare organizations aim to learn lessons from failures and incidents to make sure that they never happen again.

Maintaining and ensuring safe, efficient, and effective systems is the foundation for creating reliable systems in the Healthcare industry. Hence, innovation and transformation disrupt the existing process ecosystems and evolve them to bring in more value.

The challenge that organizations face is in their implementation and value realization with respect to cost savings, productivity enhancements, and overall revenue. The prime aspect of system reliability signifies the level of performance over time. When we consider healthcare, looking at defects alone does not differentiate reliability from the functional quality of the system. Reliability should be measured to its failure-free operation over time. Systems should be designed and implemented to focus on failure-free operation.

Measuring system operations over time can be depicted as a bathtub curve. While measuring performance, initial failure tends to arise from defects and situational factors. Eventually, the efficiency improves, and the curve flattens out to depict useful life until the wear-out phase starts from design and other situational factors.

While understanding the bathtub curve of system operations over time, we can infer that system design majorly contributes to the initial defects and system longevity. Hence, organizations must strive to build systems that can last a tenure from which the invested capital can be gained back, and the additional returns can be used for its future modernization goals.

Towards the end of the day, system reliability revolves around the following factors:

  1. Process failure prevention
  2. Identification and Mitigation of failure
  3. Process redesign for critical failure avoidance

Reliability and Stability should seriously be considered whenever healthcare systems are being implemented. This is because the industry is facing quality-related challenges. Healthcare organizations are not delivering safe, reliable, and proof-based care. Thus, it is important for professionals to be empowered with tools and modern-day functionalities that would reduce the error and risk involved in their service delivery. These modern-day tools’ reliability must be sacrosanct to ensure that stellar customer experience and patient care are given.

Organizations purely focused on cost savings as a standalone goal can lead to unpredictable outcomes. It is imperative that an organization realize robust and reliability-centered processes that define clears roles and accountability to its employees, in order to have a sustainable form of operation.

When all these factors come together, the value realizations for the organization as well as its customer base are immense. These systems can contribute towards better ROI, improved profitability, enhanced competitive advantage, and an evolved customer brand perception.

These enhanced systems improve the customer loyalty and the overall brand value.

Device Monitoring with ZIFTM

Ever since the pandemic hit, healthcare organizations have concentrated towards remote patient health monitoring, telemedicine, and operations to expedite vaccine deliveries. These healthcare organizations have invested heavily in systems that connect all the data required for day-to-day operations into one place for consolidated analysis and decision making.

For the effective functioning of these consolidated systems, each of the devices that are connected to the main system needs to be functioning to its optimal capacity. If there is a deviation in device performance and the root cause is not identified promptly, this can have adverse effects on the service delivery as well as the patient’s health.

These incidents can be addressed with ZIFTM’s OEM Device monitoring capabilities. ZIFTM can be used to provide a visual dashboard of all operational devices and monitor their health to set thresholds for maintenance, incident detection, and problem resolutions. The integration can also create a consolidated view for all logs and vital data that can be later used for processing to give predictive information for actionable insights. The end goal that ZIFTM aims to achieve here is to pivot organizations towards a proactive approach to servicing and support for the devices that are operational. This connectivity and monitoring of devices across their portfolio can substantially bring in measurable changes in its cost savings, service efficiency, and effectivity.

Prediction & Reliability Enhancement

With healthcare systems and digital services expanding across different organizations, predicting their reliability, efficiency and effectivity are important. When we look at reliability prediction, the core function is to evaluate systems and predict or estimate their failure rate.

In the current scenario, organizations are performing reliability and prediction analysis manually. Each of the resources analyzes the system to its component level and monitors its performance. This process has a high susceptibility to manual errors and data discrepancies. With ZIFTM, the integrated systems can be analyzed and modeled based on various characteristics that contribute to its systemic operation and failure. ZIFTM analyzes the system down to its component level to model and estimates each of its parameters that contribute to the system’s reliability.

The ZIFTM Empowerment

Players in the Healthcare Industry must understand that Digital Transformation is the way forward to keep up with the emerging trends and tend to its growing customer needs. The challenge comes in selecting the right technology that is worth investing and reaping its benefits within the expected time period.

Kappa (κ) Architecture – Streaming at Scale

Posted on by ZIF

We are in the era of Stream processing-as-a-service and for any data-driven organization, Stream-based computing has becoming the norm. In the last three parts https://bit.ly/2WgnILP, https://bit.ly/3a6ij2k,  https://bit.ly/3gICm88, I had explored Lambda Architecture and its variants. In this article let’s discover Streaming in the big data. ‘Real-time analytics’, ‘Real-time data’ and ‘Streaming data’ has become mandatory in any big data platform. The aspiration to extend data analysis (predictive, descriptive, or otherwise) to streaming event data has been common across every enterprise and there is a growing interest to find real-time big data architectures. Kappa (K) Architecture is one that deals with streaming. Let’s see why Real-Time Analytics matter more than ever and mandates data streaming and how streaming architecture like Kappa works. Is Kappa an alternative to lambda?

“You and I are streaming data engines.” – Jeff Hawkins

workflow automation software architecture

Questioning Lambda

Lambda architecture fits very well in many real-time use cases, mainly in re-computing algorithms. At the same time, Lambda Architecture has the inherent development and operational complexities like all the algorithms must be implemented twice, once in the cold path, the batch layer, and another execution in the hot path or the real-time layer. Apart from this dual execution path, the Lambda Architecture has the inevitable issue of debugging. Because operating two distributed multi-node services is more complex than operating one.

Given the obvious discrepancies of Lambda Architecture, Jay Kreps, CEO of Confluent, co-creator of Apache Kafka started the discussion on the need for new architecture paradigm which uses less code resource and could perform well in certain enterprise scenarios. This gave rise to Kappa (K) Architecture. The real need Kappa Architecture isn’t about efficiency at all, but rather about allowing people to develop, test, debug, and operate their systems on top of a single processing framework. In fact, Kappa is not taken as competitor to LA on the contrary it is seen as an alternative.

cognitive process automation tools for business

What is Streaming & Streaming Architecture?

Modern business requirements necessitate a paradigm shift from traditional approach of batch processing to real-time data streams. Data-centric organizations mandate the Stream first approach. Real-time data streaming or Stream first approach means at the very moment. So real-time analytics, either On-demand real-time analytics or Continuous real-time analytics, is the capability to process data right at the moment it arrives in the system. There is no possibility of batch processing of data. Not to mention, it enhances the ability to make better decision making and performing meaningful action on a timely basis. At the right place and at the right time, real-time analytics combines and analyzes data. Thus, it generates value from disparate data.

Typically, most of the streaming architectures will have the following 3 components:

  • an aggregator that gathers event streams and batch files from a variety of data sources,
  • a broker that makes data available for consumption,
  • an analytics engine that analyzes the data, correlates values and blends streams together.

Kappa (K) Architecture for Big Data era

Kappa (K) Architecture is one of the new software architecture patterns for the new Data era. It’s mainly used for processing streaming data. Kappa architecture gets the name Kappa from the Greek letter (K) and is attributed to Jay Kreps for introducing this architecture.

The main idea behind the Kappa Architecture is that both the real-time and batch processing can be carried out, especially for analytics, with a single technology stack. The data from IoT, streaming, and static/batch sources or near real-time sources like change data capture is ingested into messaging/ pub-sub platforms like Apache Kafka.

An append-only immutable log store is used in the Kappa Architecture as the canonical store. Following are the pub/sub or message buses or log databases that can be used for ingestion:

  • Amazon Quantum Ledger Database (QLDB)
  • Apache Kafka
  • Apache Pulsar
  • Amazon Kinesis
  • Amazon DynamoDB Streams
  • Azure Cosmos DB Change Feed
  • Azure EventHub
  • DistributedLog
  • EventStore
  • Chronicle Queue
  • Pravega

Distributed Stream processing engines like Apache Spark, Apache Flink, etc. will read the data from the streaming platform and transform it into an analyzable format, and then store it into an analytics database in the serving layer. Following are some of the distributed streaming computation systems

  • Amazon Kinesis
  • Apache Flink
  • Apache Samza
  • Apache Spark
  • Apache Storm
  • Apache Beam
  • Azure Stream Analytics
  • Hazelcast Jet
  • Kafka Streams
  • Onyx
  • Siddhi

In short, any query in the Kappa Architecture is defined by the following functional equation.

Query = λ (Complete data) = λ (live streaming data) * λ (Stored data)

The equation means that all the queries can be catered by applying Kappa function to the live streams of data at the speed layer. It also signifies that the stream processing occurs on the speed layer in Kappa architecture.

Pros and Cons of Kappa architecture

Pros

  • Any architecture that is used to develop data systems that doesn’t need batch layer like online learning, real-time monitoring & alerting system, can use Kappa Architecture.
  • If computations and analysis done in the batch and streaming layer are identical, then using Kappa is likely the best solution.
  • Re-computations or re-iterations is required only when the code changes.
  • It can be deployed with fixed memory.
  • It can be used for horizontally scalable systems.
  • Fewer resources are required as the machine learning is being done on the real-time basis.

Cons

Absence of batch layer might result in errors during data processing or while updating the database that requires having an exception manager to reprocess the data or reconciliation.

On finding the right architecture for any data driven organizations, a lot of considerations were taken in. Like most successful analytics project, which involves streaming first approach, the key is to start small in scope with well-defined deliverables, then iterate. The reason for considering distributed systems architecture (Generic Lambda or unified Lambda or Kappa) is due to minimized time to value.

Is AR the Future of our Increasingly Digital World?

Posted on by ZIF

Imagine a device which, when used to look at something, throws up information on whatever you’re pointing at. Menus for restaurants, dates of establishment for institutes, and so on. These are the sort of possibilities afforded by Augmented Reality (AR).

What is AR?

AR is a science fiction idea that successfully made the transition to reality. The fundamental idea behind augmented reality is to add something extra to your experience of reality. So, if you are watching a movie or playing a game, AR adds to that experience in some way or form to turn the experience immersive and interactive. AR basically superimposes computer-generated information (audio, visual, haptic, etc.) on the real-world objects.

AR can be defined as a system that fulfills three basic features: a combination of real and virtual worlds, real-time interaction, and accurate 3D registration of virtual and real objects.

How does AR work?

A camera-equipped device is essential for an AR experience. Upon pointing the device at an object, computer vision technology is used to recognize it. The device then downloads information about the object from the cloud, in much the same way that a web browser loads a page via a URL. In this case, the information is presented in a 3-D experience.

ai automated root cause analysis solution

AR can provide a view of the real-time data flowing from products and allow users to control them by touchscreen, voice, or gesture. An operator using an AR headset to interact with an industrial robot might see superimposed data about the robot’s performance and gain access to its controls.

The size and orientation of objects viewed through the AR display adjusts/changes in real-time. New graphical or text information comes into view while other information passes out of view as the user moves about. In industrial settings, users in different roles, such as a machine operator and a maintenance technician, can look at the same object but be presented with different AR experiences that are tailored to their needs.

AR – a novel way of shopping

A 2018 Gartner report stated, “By 2020, 100 million consumers will shop in AR online and in-store.” The current global pandemic has put a damper on consumer sentiments worldwide and we may not see those numbers. But AR can help make the in-store shopping experience more secure by reducing the need to touch a lot of objects and surfaces.

Brands like American Apparel, Uniqlo, and Lacoste already have showrooms and fitting rooms that provide try-before-you-buy options in AR spaces. Smart mirror technologies that scan RFID tags also offer the ability to bring recommendations to the brick-and-mortar shopping experience.

ai data analytics monitoring tools

IKEA customers have access to an app that permits them to point their phones at spaces and see what different products would look like in their own homes.

In the current global climate, fashion and lifestyle brands stand to gain from technologies that handle facial recognition, adapt to local lighting conditions, and provide personalized recommendations.

ai devops platform management services

According to a BRP report, 48% consumers said they would be more inclined to buy from a retailer that provided AR experiences. Retailers may be able to attract more customers with an immersive and secure shopping experience in a post-Corona world.

35% of sales on Amazon are derived from its recommendation engine, which is powered by Machine Learning. Leveraging this in the real world also has immense commercial potential.

AR for Navigation Solutions

Map services from Google and Apple have already found mass acceptance, indoor navigation is next. Apps based on ARKit and ARCore can enable navigating inside spaces like airports, malls, hospitals, etc. Gatwick Airport has already deployed its own smartphone solution that provides routes to terminals and gates based on a user’s flight number.

In 2019, a beta version of AR walking directions feature was launched for Google Maps for all AR-compatible iOS and Android mobile devices. You could view information about your surroundings by pointing your phone’s camera towards it.

AR in Automotive Industry

AR can be used in a breadth of ways in the automotive industry. Starting with dashboard-mounted heads-up displays to interactive experiences in showrooms and more.

AR is also employed by some carmakers to help aid in car maintenance (Volkswagen’s Marta app) and car manufacturing and selling processes (Volvo’s project with Microsoft HoloLens).

The heads-up display is one of the most popular uses of AR in this industry. Not only can drivers get directions and alerts on hazards, but also information on landmarks and nearby locations.

Hyundai has been a leader in AR research that goes beyond the cockpit-style view of the motorist’s experience. They have reimagined maintenance manuals with AR and has apps to point their phones at their cars to get information. Mercedes has a similar app, but its version adds a chatbot to provide virtual assistance.

AR in Healthcare

Applications of AR is opening up new opportunities in the healthcare industry. It’s expected that the global market will reach a value of $1.5B. By enabling healthcare workers with real-time data and patient information, AR can aid in more accurate diagnoses and more precise surgeries.

application performance management solutions

AR can also bring huge value to practicing medicine and education by allowing students and trainee physicians to better visualize health issues and scenarios that they one day will be treating. The benefit that AR can bring to the healthcare industry can be ground-breaking and we are just witnessing the beginning of what is to come from AR in the field of medicine.

AR-powered Solutions for Enterprises

Smart glasses are quickly gaining popularity. Military, medical and enterprise solutions, however, are beginning to prove the value of combining AR with headsets and smart glasses.

Microsoft HoloLens 2 was likely the most anticipated product in this space in 2019. The company hopes to roll out its technology to great fanfare by demonstrating improvements in raw processing power, battery life, and wear ability. The U.S. Army has awarded a $480 contract to Microsoft, and they are also working with the industrial IoT firm PTC to streamline the development of both augmented and mixed reality products.

applications of predictive analytics in business

Walmart and Tyson are testing programs that will transition traditional training methods into mixed reality (MR) settings. This will bring about new ways to learn about compliance and safety issues by looking around mixed-reality environments and identifying problems in a way that’s practical and engaging. Integration with other recent workplace training trends, especially gamification, may compound the returns that AR and MR solutions generate. Per ABI Research, AR-based training in enterprise will be a $6 billion industry by 2022.

Improvements in prototyping, testing, troubleshooting, and quality control are expected to emerge from this trend, too, as workers will be able to make on-the-fly comparisons of real-world items against available documentation and specifications. Jobs that call for workers’ hands to be free will also benefit significantly from AR headsets and glasses.

Augmented reality is the next ‘BIG THING’, it will absolutely revolutionize almost every aspect of life. Everything from medicine to education to construction to entertainment. AR application has already started to appear on the world’s laptops, tablets, and smartphones.

Lambda (λ), Kappa (κ) and Zeta (ζ) – The Tale of 3 AIOps Musketeers (PART-3)

Posted on by ZIF

“Data that sit unused are no different from data that were never collected in the first place.” – Doug Fisher

In the part 1 (https://bit.ly/3hDChCH), we delved into Lambda Architecture and in part 2 (https://bit.ly/3hDCg1B) about Generic Lambda. Given the limitations of the Generic lambda architecture and its inherent complexity, the data is replicated in two layers and keeping them in-sync is quite challenging in an already complex distributed system.There is a growing interest to find the simpler alternative to the Generic Lambda, that would bring just about the same benefits and handle the full problem set. The solution is Unified Lambda (λ) Architecture.

Unified Lambda (λ) Architecture

The unified approach addresses the velocity and volume problems of Big Data as it uses a hybrid computation model. This model combines both batch data and instantaneous data transparently.

There are basically three approaches:

  1. Pure Streaming Framework
  2. Pure Batch Framework
  3. Lambdoop Framework

1. Pure streaming framework

In this approach, a pure streaming model is adopted and a flexible framework like Apache Samza can be employed to provide unified data processing model for both stream and batch processing using the same data flow structure.

Pure streaming framework

To avoid the large turn-around times involved in Hadoop’s batch processing, LinkedIn came up with a distributed stream processing framework Apache Samza. It is built on top of distributed messaging bus; Apache Kafka, so that it can be a lightweight framework for streaming platform. i.e. for continuous data processing. Samza has built-in integration with Apache Kafka, which is comparable to HDFS and MapReduce. In the Hadoop world, HDFS is the storage layer and MapReduce, the processing layer. In the similar way, Apache Kafka ingests and stores the data in topics, which is then streamed and processed by Samza. Samza normally computes results continuously as and when the data arrives, thus delivering sub-second response times.

Albeit it’s a distributed stream processing framework, its architecture is pluggable i.e. can be integrated with umpteen sources like HDFS, Azure EventHubs, Kinensis etc. apart from Kafka. It follows the principle of WRITE ONCE, RUN ANYWHERE; meaning, the same code can run in both stream and batch mode. Apache Samza’s streams are re-playable, ordered partitions.

Unified API for Batch & Streaming in pure Streaming

Apache Samza offers a unified data processing model for both real-time as well as batch processing.  Based on the input data size, bounded or unbounded the data processing model can be identified, whether batch or stream.Typically bounded (e.g. static files on HDFS) are Batch data sources and streams are unbounded (e.g. a topic in Kafka). Under the bonnet, Apache Samza’s stream-processing engine handles both types with high efficiency.

Unified API for Batch & Streaming in pure Streaming

Another advantage of this unified API for Batch and Streaming in Apache Samza, is that makes it convenient for the developers to focus on the processing logic, without treating bounded and unbounded sources differently. Samza differentiates the bounded and unboundeddata by a special token end-of-stream. Also, only config change is needed, and no code changes are required, in case of switching gears between batch and streaming, e.g. Kafka to HDFS.Let us take an example of Count PageViewEvent for each mobile Device OS in a 5-minute window and send the counts to PageViewEventPerDeviceOS

Pure Batch framework

This is the reverse approach of pure streaming where a flexible Batch framework is employed, which would offer both the batch processing and real-time data processing ability. The streaming is achieved by using mini batches which is small enough to be close to real-time, with Apache Spark/Spark Streaming or Storm’s Trident. Under the hood, Spark streaming is a sequence of micro-batch processes with the sub-second latency. Trident is a high-level abstraction for doing streaming computation on top of Storm. The core data model of Trident is the “Stream”, processed as a series of batches.

Apache Spark achieves the dual goal of Batch as well as real-time processing by the following modes.

  • Micro-batch processing model
  • Continuous Processing model

Micro-batch processing model

Micro-batch processing is analogous to the traditional batch processing in that data are usually processed as a group. The primary difference is that the batches are smaller and processed more often. In spark streaming, the micro-batches are created based on the time rather than on the accumulated data size. The smaller the time to trigger a micro-batch to process, lesser the latency.

Continuous Processing model

Apache Spark 2.3, introduced Low-latency Continuous Processing Mode in Structured Streaming whichenables low (~1 ms) end-to-end latency with at-least-once fault-tolerance guarantees. Comparing this with the default micro-batch processing engine which can achieve exactly-once guarantees but achieve latencies of ~100 ms at best. Without modifying the application logic i.e. DataFrame/Dataset operations mini-batching or continuous streaming can be chosen at runtime. Spark Streaming also has the abilityto work well with several data sources like HDFS, Flume or Kafka.

Example of Micro-batching and Continuous Batching

3. Lambdoop Approach

In many places, capability of both batch and real time processing is needed.It is cumbersome to develop a software architecture of such capabilities by tailoring suitable technologies, software layers, data sources, data storage solutions, smart algorithms and so on to achieve the good scalable solution. This is where the frameworks like Spring “XD”, Summingbird or Lambdoop comes in, since they already have a combined API for batch and real-time processing.

Lambdoop

Lambdoop is a software framework based on the Lambda architecture which provides an abstraction layer to the developers. This feature makes the developers life easy to develop any Big Data applications by combining real time and batch processing approaches. Developers don’t have to deal with different technologies, configurations, data formats etc. They can use the Lambdoop framework as the only needed API. Also, Lambdoop includes other interesting tools such as input/output drivers, visualization tools, cluster management tools and widely accepted AI algorithms.

The Speed layer in Lambdoop runs on Storm and the Batch layer on Hadoop, Lambdoop (Lambda-Hadoop, with HBase, Storm and Redis) also combines batch/real-time by offering a single API for both processing models.

Summingbird

Summingbird aka‘Streaming MapReduce’ is a hybrid computational system where both the batch/streaming computations can be run at the same time and the results can be merged automatically. In Summingbird, the developer can write the code/job logic once and change the backend as and when needed. Following are the modes in which Summingbird Job/code can be executed.

  • batch mode (using Scalding on Hadoop)
  • real-time mode (using Storm)
  • hybrid batch/real-time mode (offers attractive fault-tolerance properties)

If the model assumes streaming, one-at-a-time semantics, then the code can be run in real-time e.g. Strom or in offline/batch mode e.g. Hadoop, spark etc. It can operate in a hybrid processing mode, when there is a need to transparently integrate batch and online results to efficiently generate up-to-date views over long time spans.

Conclusion

The volume of any Big Data platform is handled by building a batch processing application which requires, MapReduce, spark development, Use of other Hadoop related tools like Sqoop, Zookeeper, HCatalog etc. and storage systems like HBase, MongoDB, HDFS, Cassandra. At the same time the velocity of any Big Data platform is handled by building a real-time streaming application which requires, stream computing development using Storm, Samza, Kafka-connect, Apache Flink andS4, and use of temporal datastores like in-memory data stores, Apache Kafka messaging system etc.

The Unified Lambda handles the both Volume and Velocity if any Big Data platform by the intermixed approach of featuring a hybrid computation model, where both batch and real-time data processing are combined transparently. Also, the limitations of Generic Lambda like Dual execution mode, Replicating and maintaining the data sync between different layers are avoided and in the Unified Lambda, there would be only one system to learn and maintain.

Growing Importance of Business Service Reliability

Posted on by ZIF

Business services are a set of business activities delivered to an outside party, such as a customer or a partner. Successful delivery of business services often depends on one or more IT services. For example, an IT business service that would support “order to cash”, as an example could be “supply chain service”. The supply chain service could be delivered by an application such as SAP, with the customer of that service being an employee in finance/accounting using the application to perform customer-facing services such as accounts receivable, or the collection of cash from an outside party. A business service is not simply the application that the end-user sees – it is the entire chain that supports the delivery of the service, including physical and virtualized servers, databases, middleware, storage, and networks. A failure in any of these can affect the service – and so it is crucial that IT organizations have an integrated, accurate, and up-to-date view of these components and of how they work together to provide the service.

The technologies for Social Networking, Mobile Applications, Analytics, Cloud (SMAC), and Artificial Intelligence (AI) are redefining the business and the services that businesses provide. Their widespread usage is changing the business landscape, increasing reliability and availability to levels that were unimaginable even a few years ago.

Availability versus Reliability

At first glance, it might seem that if a service has a high availability then it should also have high reliability. However, this is not necessarily the case. Availability and Reliability have different meanings, serve different purposes, and require different strategies to maintain desired standards of service levels. Reliability is the measure of how long a business service performs its intended function, whereas availability is the measure of the percentage of time a business service is operable. For example, a business service may be available 90% of the time, but reliable only 75% of the time from a performance standpoint. Service reliability can be seen as:

  • Probability of success
  • Durability
  • Dependability
  • Quality over time
  • Availability to perform a function

Merely having a service available isn’t sufficient. When a business service is available, it should actually serve the intended purpose under varying and unexpected conditions. One way to measure this performance is to evaluate the reliability of the service that is available to consume. The performance of a business service is now rated not by its availability, but by how consistently reliable it is. Take the example of mobile services – 4 bars of signal strength on your smartphone does not guarantee that the quality of the call you received or going to make. Organizations need to measure how well the service fulfills the necessary business performance needs.

Recognizing the importance of reliability, Google initiated Site Reliability Engineering (SRE) practices with a mission to protect, provide for, and progress the software and systems behind all of Google’s public services — Google Search, Ads, Gmail, Android, YouTube, and App Engine, to name just a few — with an ever-watchful eye on their availability, latency, performance, and capacity.

Machine Learning: Building Clustering Algorithms

Posted on by ZIF

Gireesh Sreedhar KP


Clustering is a widely-used Machine Learning (ML) technique. Clustering is an Unsupervised ML algorithm that is built to learn patterns from input data without any training, besides being able of processing data with high dimensions. This makes clustering the method of choice to solve a wide range and variety of ML problems.

Since clustering is widely used, for Data Scientists and ML Engineer’s it is critical to understand how to practically build clustering algorithms even though many of us have a high-level understanding of clustering. Let us understand the approach to build a clustering algorithm from scratch.

What is Clustering and how does it work?

Clustering is finding groups of objects (data) such that objects in the same group will be similar (related) to one another and different from (unrelated to) objects in other groups.

Clustering works on the concept of Similarity/Dissimilarity between data points. The higher similarity between data points, the more likely these data points will belong to the same cluster and higher the dissimilarity between data points, the more likely these data points will be kept out of the same cluster.

Similarity is the numerical measure of how alike two data objects are. Similarity will be higher when objects are more alike. Dissimilarity is the numerical measure of how different two data objects. Dissimilarity is lower when objects are more alike.

We create a ‘Dissimilarity Matrix’ (also called Distance Matrix) as an input to a clustering algorithm, where the dissimilarity matrix gives algorithm the notion of dissimilarity between objects. We build a dissimilarity matrix for each attribute of data considered for clustering and then combine the dissimilarity matrix for each data attribute to form an overall dissimilarity matrix. The dissimilarity matrix is an NxN square matrix where N is the number of data points considered for clustering and each element of the NxN square matrix gives dissimilarity between two objects.

Building Clustering Algorithm

Building a clustering algorithm involve the following:

  • Selection of most suited clustering techniques and algorithms to solve the problem. This step needs close collaboration among SMEs, business users, data scientists, and ML engineers. Based on inputs and data study, a possible list of algorithms (one or more) is selected for modeling and development along with tuning parameters are decided (to give algorithm more flexibility for tuning and learning from SME).
  • The selection of data attributes for the formulation of the dissimilarity matrix and methodology for the formation of the dissimilarity matrix (discussed later).
  • Building algorithms and doing the Design of experiments to select the best-suited algorithm and algorithm parameters for implementation.
  • Implementation of algorithm and fine-tuning of parameters as required.

Building a Dissimilarity matrix:

There are different approaches to build a dissimilarity matrix, here we consider building a dissimilarity matrix containing the distance (called Distance Matrix) between data objects (another alternative approach is to feed in coordinate points and let the algorithm compute distance). Let us consider a group of N data objects to be clustered based on three data attributes of each data object. The steps for building a Distance matrix are:

Build a Distance matrix for individual data attributes. Here we build three individual distance matrices (one for each attribute) containing distance between data objects calculated for each attribute. The data is always scaled between [0,1] using one of the standard normalization methods such as Min-Max Scalar. Here is how the distance matrix for an attribute looks like.

Properties of Distance Matrix:

  1. Distance Matrix is NxN square matrix (N – number of objects in clustering space)
  2. Matrix is symmetric with diagonal as zero (zero diagonal as distance of an object from itself is zero)
  3. For categorical data, distance between two points = 0, if both are same; =1 otherwise
  4. For numeric/ordered data, distance between two points = difference between scaled attribute values of two points.

Build Complete Distance matrix. Here we build a complete distance matrix combining distance matrix of individual attributes forming the input for clustering algorithm.

Complete distance matrix = (element-wise sum of individual attribute level matrix)/3;

Generalized Complete distance matrix = (element-wise sum of individual attribute level matrix)/M, where M is the number of attribute level matrix formed.

Considerations for the selection of clustering algorithms:

Before the selection of a clustering algorithm, the following considerations need to be evaluated to identify the right clustering algorithms for the given problem.

  • Partition criteria: Single Level vs hierarchical portioning
  • Separation of clusters: Exclusive (one data point belongs to only one class) vs non-exclusive (one data point can belong to more than one class)
  • Similarity measures: Distance-based vs Connectivity-based
  • Clustering space: Full space (used when low dimension data is processed) vs Subspace (used when high dimension data is processed, where only subspace can be processed and interesting clustering can be formed)
  • Attributes processing: Ability to deal with different types of attributes: Numerical, Categorical, Text, Media, a combination of data types in inputs
  • Discovery of clusters: Ability to form a predefined number of clusters or an arbitrary number of clusters
  • Ability to deal with noise in data
  • Scalability to deal with huge volumes of data, high dimensionality, incremental, or streaming data.
  • Ability to deal with constraints on user preference and domain requirements.

Application of Clustering

There are broadly two applications of clustering.

As an ML tool to get insight into data. Like building Recommendation Systems or Customer segmentation by clustering like-minded users or similar products, Social network analysis, Biological data analysis like Gene/Protein sequence analysis, etc.

As a pre-processing or intermediate step for other classes of algorithms. Like some Pattern-mining algorithms use clustering to group patterns mined and select most representative patterns instead of selecting entire patterns mined.

Conclusion

Building ML algorithm is teamwork with a team consisting of SMEs, users, data scientists, and ML engineers, each playing their part for success. The article gives steps to build a clustering algorithm, this can be used as reference material while attempting to build your algorithm.

Modern IT Infrastructure

Posted on by ZIF

Infrastructure today has grown beyond the physical confines of the traditional data center, has spread its wings to the cloud, and is increasingly distributed, virtual, and abstract. With the cloud gaining wide acceptance, most enterprises have their workloads spread across data centers, colocations, multi-cloud, and edge locations. On-premise infrastructure is also being replaced by Hyperconverged Infrastructure (HCI) where software-defined, virtualized compute, storage, and network are in one single system, greatly simplifying IT operations. Infrastructure is also becoming increasingly elastic, scales & shrinks on demand and doesn’t have to be provisioned upfront.

Let’s look at a few interesting technologies that are steering the modern IT landscape.

Containers and Serverless

Traditional application deployment on physical servers comes with the overhead of managing the infrastructure, middleware, development tools, and everything in between. Application developers would rather have this grunt work be handled by someone else, so they could focus on just their applications. This is where containers and serverless technologies come into picture. Both are cloud-based offerings and provide different levels of abstraction, in a way that hides layers beyond the front end, from the developer. They typically deploy smaller components of monolithic applications, microservices, and functions.

A Container is like an all-in-one-box, containing the app, and all its dependencies like libraries, executables & config files. The containerized application is highly portable, will run anywhere the container runtime is installed, and behave the same regardless of the OS or hardware it is deployed on. Containers give developers great flexibility and control since they cater to specific application requirements like the OS, S/W versions. The flip side is that there is still a need for manual maintenance of the runtime environment, like security patches, software updates, etc. Secondly, the flexibility it affords translates into high operational costs, since it lacks agility in scaling.

Serverless technologies provide much greater abstraction of the OS and infrastructure. ‘Serverless’ though, does not imply that there are no servers, it just means application developers do not have to worry about the underlying OS, the server environment, or the infra that their applications will be deployed on. Serverless is event-driven and is based on the premise that the application is split into functions that get executed based on events. The developer only needs to deploy function code and define the event(s) that will trigger them! The rest of the magic is done by the cloud service provider (with the help of third parties). 

The biggest advantage of serverless is that consumers are billed only for the running time of the function instances or the number of times the function gets executed, depending on the provider. Since it has zero administrative overhead, it guarantees rapid iterative deployment and faster time to market. Since the architecture is intrinsically auto-scaling, it is a perfect fit for applications with undefinable usage patterns. The other side of the coin is that developers need to deal with a black box back-end environment, so, holistic testing, debugging of the application becomes a challenge. Vendor lock-in is a real problem since the consumer is restricted by the technology stack supported by the vendor. Since serverless best practices dictate light, isolated functions with limited scope, building complex applications can get difficult. Function as a Service (FaaS) is a subset of serverless computing.

Internet of Things (IoT)

IoT is about connecting everyday things – beyond just computing devices or smartphones – to the internet. It is possible to convert practically anything into an IoT device, with a computer chip installation & internet access, and have it communicate independently with the internet – without any human intervention. But why would we want everyday things like for instance a watch or a light bulb, to become IoT devices? It’s in a bid to bridge the chasm between the physical and digital worlds and make the environment around us more intelligent, communicative, and responsive to our needs.

IoT’s use cases are just about everywhere; in personal devices, self-driving cars, smart homes, smart workspaces, smart cities, and industries across all verticals. For instance, live data from sensors in products while in use, gives good visibility into their operations on the ground, helps remediate issues proactively & aids improvements in design/manufacturing processes.

The Industrial Internet of Things (IIoT) is the use of IoT data in business, in tandem with Big Data, AI, Analytics, Cloud, and High-speed networks, with the primary goal of finding efficient business models to improve productivity & optimize expenditure. The need for real-time response to sensor data and advanced analytics to power insights has increased the demand for 5G networks for speed, cloud technologies for storage and computing, edge computing to reduce latency, and hyper-scale data centers for rapid scaling.

With IoT devices extending an organization’s infrastructure landscape, and the likelihood that IT staff may not even be aware of all the IoT devices in it is a security nightmare that could open corporate networks & sensitive data for attacks. Global standards and regulations for IoT device security are in the works. Until then, it is up to the enterprise security team to safeguard against IoT-related vulnerabilities.

Hyperscaling

The ability of infrastructure to rapidly scale out on a massive level is called hyperscaling.

Unprecedented needs for high-power computing and on-demand massive scalability has given rise to a new breed of hyperscale computing architectures, where traditional elements are replaced by hyper-converged, software-defined infrastructure with a high degree of virtualization. These hyperscale environments are characterized by high-density server racks, with software designed and specifically built for scale-out environments. Since high-density implies heavy power consumption, heating problems need to be handled by specialized cooling solutions like liquid cooling. Hyperscale data centre operators usually look for renewable energy options to save on power & cooling.

Today, there are several hundred hyperscale data centers in the world, with the dominant players being Microsoft, Google, Apple, Amazon & Facebook.

Edge Computing

Edge computing as the name indicates means moving data processing away from distant servers or the cloud, closer to the source of data.  This is to reduce latency and network bandwidth used for back & forth communication between the data source and the server. Edge, also called the network edge refers to where the data source connects to the internet. The explosive growth of IoT and applications like self-driving cars, virtual reality, smart cities for instance, that require real-time computing and analytics are paving the way for edge computing. Most cloud providers now provide geographically distributed edge servers. As with IoT devices, data at the edge can be a ticking security time bomb necessitating appropriate security mechanisms.

The evolution of IT technologies continuously raises the bar for the IT team. IT personnel have been forced to move beyond legacy practices and mindsets & constantly up-skill themselves to be able to ride the wave. For customers pampered by sophisticated technologies, round the clock availability of systems and immersive experiences have become baseline expectations. With more & more digitalization, there is increasing reliance on IT infrastructure and hence lesser tolerance for outages. The responsibilities of maintaining a high-performing IT infrastructure with near-zero downtime fall on the shoulders of the IT operations team.

This has underscored the importance of AI in IT operations since IT needs have now surpassed human capabilities. Gavs’ AI-powered Platform for IT operations, ZIF, caters to the entire ITOps spectrum, right from automated discovery of the landscape, monitoring, to predictive and prescriptive analytics that proactively drive the organization towards zero incidents.

The Hands that rock the cradle, also crack the code

Posted on by ZIF

It was an unguarded moment for my church-going, straight-laced handyman & landscaper, “ I am not sure if I am ready to trust a woman leader”, and finally the loss of first woman Presidential candidate in the US, that led me to ruminate about Women and Leadership and indulge in my most “ time suck” activities, google and peruse through Wikipedia.

I had known about this, but I was fascinated to reconfirm that the first programmer in the world was a woman, and daughter of the famed poet, Lord Byron, no less. The first Programmer in the World, Augusta Ada King-Noel, Countess of Lovelace nee Byron; was born in 1815 and was the only legitimate child of the poet laureate, Lord Byron and his wife Annabella. A month after Ada was born, Byron separated from his wife and forever left England. Ada’s mother remained bitter towards Lord Byron and promoted Ada’s interest in mathematics and logic in an effort to prevent her from developing what she saw as the insanity seen in her father.

Ada grew up being trained and tutored by famous mathematicians and scientists. She established a relationship with various scientists and authors, like Charles Dickens, etc..   Ada described her approach as “poetical science”[6] and herself as an “Analyst & Metaphysician”.

As a teenager, Ada’s prodigious mathematical talents, led her to have British mathematician Charles Babbage, as her mentor. By then Babbage had become very famous and had come to be known as ‘the father of computers’. Babbage was reputed to have developed the Analytical Engine. Between 1842 and 1843, Ada translated an article on the Analytical Engine, which she supplemented with an elaborate set of notes, simply called Notes. These notes contain what many consider to be the first computer program—that is, an algorithm designed to be carried out by a machine. As a result, she is often regarded as the first computer programmer. Ada died at a very young age of 36.

As an ode to her, the mathematical program used in the Defense Industry has been named Ada. And to celebrate our first Programmer, the second Tuesday of October has been named Ada Lovelace Day. ALD celebrates the achievement of women in Science, Technology and Engineering and Math (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM.

Most of us applauded Benedict Cumberbatch’s turn as Alan Turing in the movie,  Imitation Game. We got to know about the contribution, that Alan Turning and his code breaking team at the Bletchley Park, played in singularly cracking the German Enigma code and how the code helped them to proactively know when the Germans were about to attack the Allied sites and in the process could conduct preemptive strikes. In the movie, Kiera Knightly played the role of Joan Clark.  Joan was an English code-breaker at the British Intelligence wing, MI5, at Bletchley Park during the World War II. She was appointed a Member of the Order of the British Empire (MBE) in 1947, because of the important part she essayed in decoding the famed German Enigma code along with Alan Turing and the team.

Joan Clark attended Cambridge University with a scholarship and there she gained a double first degree in mathematics. But the irony of it all was that she was denied a full degree, as till 1948, Cambridge only awarded degrees to men. The head of the Code-breakers group, Hugh Alexander,  described her as “one of the best in the section”, yet while promoting Joan Clark, they had initially given her a job title of a typist, as women were not allowed to be a Crypto Analyst. Clarke became deputy head of British Intelligence unit, Hut 8 in 1944.  She was paid less than the men and in the later years she believed that she was prevented from progressing further because of her gender.

In World War II the  US Army was tasked with a Herculean job to calculate the trajectories of ballistic missiles. The problem was that each equation took 30 hours to complete, and the Army needed thousands of them. So the Army, started to recruit every mathematician they could find. They placed ads in newspapers;  first in Philadelphia, then in New York City, then in far out west in places like Missouri, seeking women “computers” who could hand-compute the equations using mechanical desktop calculators. The selected applicants would be stationed at the  University of Pennsylvania in Philly. At the height of this program, the US Army employed more than 100 women calculators. One of the last women to join the team was a farm girl named Jean Jennings. To support the project, the US Army-funded an experimental project to automate the trajectory calculations. Engineers John Presper Eckert and John W. Mauchly, who are often termed as the Inventors of Mainframe computers, began designing the Electronic Numerical Integrator and Computer, or ENIAC as it was called.  That experimenting paid off: The 80-foot long, 8-foot tall, black metal behemoth, which contained hundreds of wires, 18,000 vacuum tubes, 40 8-foot cables, and 3000 switches, would become the first all-electric computer called ENIAC.

When the ENIAC was nearing completion in the spring of 1945, the US Army randomly selected six women, computer programmers,  out of the 100 or so workers and tasked them with programming the ENIAC. The engineers handed the women the logistical diagrams of ENIAC’s 40 panels and the women learned from there. They had no programming languages or compilers. Their job was to program ENIAC to perform the firing table equations they knew so well.

The six women—Francis “Betty” Snyder Holberton, Betty “Jean” Jennings Bartik, Kathleen McNulty Mauchly Antonelli, Marlyn Wescoff Meltzer, Ruth Lichterman Teitelbaum, and Frances Bilas Spence—had no documentation and no schematics to work with.

There was no language, no operating system, the women had to figure out what the computer was, how to interface with it, and then break down a complicated mathematical problem into very small steps that the ENIAC could then perform.  They physically hand-wired the machine,  using switches, cables, and digit trays to route data and program pulses. This might have been a very complicated and arduous task. The ballistic calculations went from taking 30 hours to complete by hand to taking mere seconds to complete on the ENIAC.

Unfortunately, ENIAC was not completed in time, hence could not be used during World War II. But 6 months after the end of the war, on February 14, 1946 The ENIAC was announced as a modern marvel in the US. There was praise and publicity for the Moore School of Electrical Engineering at the University of Pennsylvania, Eckert and Mauchly were heralded as geniuses. However, none of the key programmers, all the women were not introduced in the event. Some of the women appeared in photographs later, but everyone assumed they were just models, perfunctorily placed to embellish the photograph.

After the war, the government ran a campaign asking women to leave their jobs at the factories and the farms so returning soldiers could have their old jobs back. Most women did, leaving careers in the 1940s and 1950s and perforce were required to become homemakers. Unfortunately, none of the returning soldiers knew how to program the ENIAC.

All of these women programmers had gone to college at a time when most men in this country didn’t even go to college. So the Army strongly encouraged them to stay, and for the most part, they did, becoming the first professional programmers, the first teachers of modern programming, and the inventors of tools that paved the way for modern software.

The Army opened the ENIAC up to perform other types of non-military calculations after the war and Betty Holberton and Jean Jennings converted it to a stored-program machine. Betty went on to invent the first sort routine and help design the first commercial computers, the UNIVAC and the BINAC, alongside Jean. These were the first mainframe computers in the world.

Today the Indian IT  industry is at $ 160 B and is at 7.7 %age of the Indian GDP and employs approximately 2.5 Million direct employees and a very high percentage of them are women. Ginni Rommeti, Meg Whitman are the CEOs of IBM and HP while Sheryl Sandberg is the COO of Facebook. They along with Padmasree Warrior, ex CTO of CISCO have been able to crack the glass ceiling.    India boasts of Senior Leadership in leading IT companies like Facebook, IBM, CapGemini, HP, Intel  etc.. who happen to be women. At our company, GAVS, we are making an effort to put in policies, practices, culture that attract, retain, and nurture women leaders in IT. The IT industry can definitely be a major change agent in terms of employing a large segment of women in India and can be a transformative force for new vibrant India. We must be having our Indian Ada, Joan, Jean and Betty and they are working at ISRO, at Bangalore and Sriharikota, at the Nuclear Plants at Tarapur.
