This pattern provides a mediator class which normally handles all the communications between different classes and supports easy maintenance of the code by loose coupling. Mediator pattern falls under behavioural pattern category.   Basically, a Mediator perform 2 operations. · Accept the incoming request · Handles the incoming request and provide the response. CQRS  +  Mediator  Patterns are prefered over large projects. Advantages of CQRS Independent scaling Optimized data transfer objects Prov

  What are microservices? Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are Highly maintainable and testable Loosely coupled Independently deployable Organized around business capabilities Owned by a small team The microservice architecture enables the rapid, frequent and reliable delivery of large, complex applications. It also enables an organization to evolve its technology stack.
