How Protocol buffers were designed to solve many problems? Also how to generate Java or Scala code? In order to continue our series, we will try to create a small basic application with simple client requests Continue Reading
Reading Time: 4 minutes It would be beneficial if you understand the concepts of Reactive Architecture before diving into Reactive Microservices. You can read about Reactive Architecture here: Leaning Towards Reactive Architecture In this article we will cover transition from Monoliths to Service Oriented Architecture to Reactive Microservices by applying isolation techniques to the application. What are Monoliths? To start explaining the microservices it’s useful to compare it to Continue Reading
Reading Time: 8 minutes Hi all. In this blog we will see how we can leverage spring boot and Eureka server to do a Service Registry and Discovery. In the world of microservices scalability and elasticity is mandatory. That means, we can scale our services both up and down to meet the variant load requirements. Typically, this includes creating and destroying the instances of our services. Microservices communicate with Continue Reading
