What is MicroService? MicroService යනු තනි application එකක් (Monolithic Application එකක්), එකිනෙක communicate කරගන පුළුවන් වෙන වෙනම deploy වන කුඩා කුඩා independent services වලට කැඩීමයි. Simply it is new way to develop application rather than traditional monolithic application. Companies which are using microservice.   Features of MicroService Architecture Small focused – main aim of microservice is simplicity.it can be rewrite in maintained without extra effort. Loosely coupled – development as well as deployment is quick. Language Neutral – few services can be Java, few is c# few can be python.it can be use depend on the service. Bounded Context – each microservice does not need to understand the implementation of the other microservice.
