What are the key concepts of Microservice architecture?

The microservices style is usually organized around business capabilities and priorities. Unlike a traditional monolithic development approach—where different teams each have a specific focus on, say, UIs, databases, technology layers, or server-side logic—microservice architecture utilizes cross-functional teams .

A typical Microservice Architecture (MSA) should consist of the following components:

Microservices are small, each running in their own process, using lightweight communication mechanisms and built around business capabilities . Applications (Apps) are larger but still small, separate, runnable processes, using a share-nothing model that share many characteristics with microservices..
