Automated Rest services testing using REST Assured library. Introductory guide for REST Assured library. basic understanding of its use and requirement.
Consider a situation where a microservice is deployed on multiple pods and on condition one pod got restarted with any of the failure reason makes unreachable and at the same time interdependent services are registers its IP for communication. Now, since other pods of the service are alive but not able to communicate makes the communication failure as well as making the failure of every Continue Reading
Hello everyone, it’s been quite a while now since I started working on Lagom(java) and it was only recently when I came across a scenario wherein I was required to override the ErrorHandler provided by Play in my Lagom microservice. As you all already know that Lagom is built on top of Play and Akka, so there will be times when we’ll be required to Continue Reading
In this blog, we are going to discuss an amazing tool used for service discovery and configuring services using Consul. Hold on a second!! There must be some questions in your mind: Aren’t there so many tools already doing that and are being used by everyone? Wow !! I have been using tools like Zookeeper for service discovery, And they are pretty good. Now, do Continue Reading
Today we are to going to talk about a very important aspect of reactive web applications development. It’s not from the alien world, we always talk about it but we rarely want to deal with it. It’s Cache. In today’s mammoth scalable architecture, we are mostly surrounded by big design issues and somewhere here and there we neglect benefits of using a very useful concept Continue Reading
Hi readers, this is my second blog on AWS lambda, I covered the basics in my previous blogs. Now we will focus on the implementation part. Before starting, please keep a check on these things: Prerequisite Setup your AWS account, click here Understanding what AWS Lambda is? click here All set let’s start.
Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. It implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency. Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols. Today here I am going to implement the Finagle example using Scala where I am sending the request with some message Continue Reading
Ever wondered why do companies like Apple, eBay and Netflix care so much about microservices? What makes this simple architecture so special that it is being hyped so much? Is it worth the pain and efforts to shift an entire running application from monolithic to microservices architecture? Many such questions came to our minds when we started using the microservices in our projects. In this Continue Reading
For those of you who are already familiar with Lagom services, this blog post should be a breeze, and you can skip directly to Section B, where the primary focus is to differentiate between three possible ways to implement a service call in Lagom. And for those of you who are new to Lagom, I’ll make sure there is a small brief and enough links Continue Reading
GraphQL is an API standard that provides a more efficient, powerful and flexible alternative to REST. It was created by Facebook in 2012 and was open-sourced in 2015 and is now maintained by a large community of companies and individuals from all over the world. GraphQL is just a specification, meaning it’s just a set of rules defined in a document. GraphQL is a query language designed Continue Reading
Apart from speed, high-performance, fault-tolerance and concurrency, one more most important feature for an api is a clean, precise, interactive and user friendly documentation. Documentation plays a very important role in a rest api. The interactive documentation makes api more easy and understandable. Finatra is fast, testable, Scala services built on Twitter-Server and Finagle, similarly Swagger is a well known api documentation framework. In this blog we are going Continue Reading
