Background In this current era, Distributed Architecture has become de-facto architectural paradigm, which necessitates implementation of loosely coupled Microservices which would talk with each other via REST API Message Oriented Middleware As far as Message Oriented Middleware is concerned, Apache Kafka has become …

Background In today's contemporary world of enterprise software where massively used applications are expected to scale and run seamlessly at extreme high loads e.g. Scaling Hotstar for 25.3 million users, system performance becomes one of the key tenant of architecting high throughput, low latency applications along …

Background In couple of my previous articles I not only tried helping understand fundamentals of JVM memory management, but also delved deeper to understand how Garbage Collection works along with its optimization. So with this background, I am sure you would be convinced that behavior of garbage collection may have …

Background In one of my previous post we saw tangible advantages (w.r.t throughput, latency and resource utilization) of refactoring existing Microservice application from imperative to reactive constructs. So an obvious question that comes to an inquisitive mind - Can we apply Reactive principles to the underlying …

Background In my previous post I tried demonstrating how to implement an optimal and performant REST client using RestTemplate In this article I will be demonstrating similar stuff but by using WebClient. But before we get started, lets try rationalizing Why yet another REST client i.e. WebClient IMO there are 2 …

Background In this contemporary world of enterprise application development, Microservice Architecture has become defacto paradigm. With this new paradigm, an application is going to have myriad set of independent and autonomous (micro)services which will be calling each other. One of the fundamental characteristics of …

Background As software industry is embracing the new Microservice Architecture paradigm, myriad applications have been built with Spring Boot framework. By the time organizations have got its early versions of microservice applications in production, industry has found out newer and better avenues for further …

Now that twenty-twenties i.e. 2020 has just commenced, I just thought to reflect upon the bygone year 2019 as a casual and occasional blogger. This in my opinion will definitely help me to introspect, analyse and thereby identify hits and misses, which eventually will lead me to improve upon my shortcomings / …

In one of my previous post I elaborated basics of JVM memory and also explained how garbage collection works. In this post we will try to understand various types of GC and how to tune and optimize them with a real world example. GC Taxonomy 1. Minor GC When garbage is collected from Young space it is called Minor GC. …

Background From first part of blog we gathered understanding about basics of Chaos Engineering. Now we will further deep dive to understand how to perform Chaos Engineering with a working example - which to me is going to be quite interesting. First lets start with understanding basics of working example which will be …
