  • Istio Circuit Breaker with Outlier Detection

    By on • ( 5 )

    Istio Outlier Detection

    Outlier Detection is an Istio Resiliency strategy to detect unusual host behavior and evict the unhealthy hosts from the set of load balanced healthy hosts inside a cluster. It automatically tracks the status of each individual host and checks metrics like consecutive errors and latency associated with service calls. If it finds outliers, it will automatically evict them.

    Prometheus Architecture

    Prometheus is an open source metrics-based monitoring and alerting system. In 2016 the Prometheus project became the second member of the Cloud Native Computing Foundation, after Kubernetes. It has a powerful query language(PromQL) with a multidimensional data model suited to store time series data.

  • Microservices Journey from Netflix OSS to Istio Service Mesh

    By on • ( 1 )

    Netflix OSS is a set of libraries & framework that Netflix open sourced to solve the issues with designing distributed systems at scale. In this blog post, you will understand the issues with the Netflix OSS libraries and why organizations are adapting the Sidecar Design pattern and Service Mesh technologies.

  • Istio Service Mesh Data Plane

    By on • ( 2 )

    Istio Architecture

    The Istio Data Plane is primarily comprised of the Envoy proxies which are attached as dedicated sidecars to each application instance. Istio Data Plane intercepts all incoming(Ingress) and outgoing(Egress) network traffic. This and gives us the ability to apply all the features at this layer, without polluting the application code.

  • Istio Service Mesh Control Plane

    By on • ( 3 )

    Istio is a very popular Service Mesh Framework which uses Lyft’s Envoy as the sidecar proxy. Service Mesh gives you the freedom of not having to worry about the service to service communication as part of your application code. Instead of bloating your microservice with similar functionalities, you can let the Service Mesh handle that complexity for you.

    Fallacies of Distributed Computing

    The Eight Fallacies of Distributed Computing are a set of assumptions that developers make while designing Distributed Systems which might backfire and cause additional work and system redesign in the long run. Designing Distributed Systems is challenging and being aware of these eight fallacies will help you in architecting your systems better.

  • My Favorite Feature in Azure Data Studio

    By on • ( 1 )

    Azure Data Studio provides a lot of Extensibility options and its Extension Model is actually my favorite feature of this tool. There is no need of huge software installs and in the process getting tools/functionalities which you don’t require. The base install of Azure Data Studio is very small & lightweight. With Azure Data Studio you can customize your environment with the tooling you need. Extensions provide an easy way to add more functionality to the installation.

  • Simplifying Microservice Architecture with Envoy and Istio

    By on • ( 4 )

    Microservices are complex and building a scalable and resilient Microservice architecture is challenging. By using Kubernetes, Envoy and Istio you can reduce the complexity associated with your services.

  • SonarQube – Issues with Cyclomatic Complexity Metrics

    By on • ( 1 )

    We have been using SonarQube for inspecting code quality of our applications for a long time now. We have integrated SonarQube with our CI/CD Pipeline and configured Quality Gates — hence with every code check in we perform a static code analysis of the changes. This provides developers an early feedback of their code changes. If the code changes does not meet quality standards, the code check-in is rejected.

  • Kubernetes Architecture

    By on • ( 0 )

     If you are building cloud native applications, Kubernetes is a game changer in this space and lets you build and deploy reliable, scalable and highly available distributed systems. In this blog, we will discuss about the Kubernetes architecture and look at the various components of the Master and Worker Nodes.

  • Making your Microservices Resilient and Fault Tolerant

    By on • ( 3 )

    While architecting distributed cloud applications, you should assume that failures will happen and design your applications for resiliency. A Microservice ecosystem is going to fail at some point or the other and hence you need to learn embracing failures.
