Microservices architecture

Microservices, aka microservice architecture, is an architectural style that structures an application as a collection of small autonomous services, modeled around a business domain . In a Microservice Architecture, each service is self-contained and implements a single business capability.

A microservices framework takes a big monolithic architecture that isn’t easy to maintain or change and make it easier to scale, replace, and change . Microservices address the concerns of the bigger systems, creating a framework that is a set of services that communicate using a messaging system such as REST over HTTP.

A microservice attempts to address a single concern, such as a data search, logging function, or web service function . This approach increases flexibility—for example, updating the code of a single function without having to refactor or even redeploy the rest of the microservices architecture.
