A microservice architecture, which is a variation of the service-oriented architecture (SOA) structural style, divides an application into loosely connected services. The services in a microservices architecture are fine-grained, and the protocols are light. The idea is for teams to be able to bring their services to life without relying on others. Loose coupling lowers all forms of dependencies and the complications that come with them because service developers don't have to worry about the service's users, and they don't force their modifications on them.
It lets software development companies to scale quickly and easily while also making it easy to leverage off-the-shelf services. There are fewer communication requirements.
Maintaining the decoupling, though, comes at a cost. Interfaces must be properly created and treated as public APIs. To avoid breaking existing users' code, techniques like as having several interfaces on the same service or multiple versions of the same service are used.

Microservices are divided into two categories.
Any distributed application's foundation is made up of stateless services. The session state of such microservices is not maintained across requests. If a service is removed from the application, it will have no effect on how the service is processed. Furthermore, it would be included as part of the overall application.
Each microservice is self-contained. The stateful microservices keep a service request state when two or more microservices communicate. They accomplish this by saving session data within the code. It is preferable to use stateful services in circumstances when session information must be saved.
Microservices deployment best practices is to utilize the Multiple Service Instances per Host design. When utilizing this pattern, your arrangement at least one physical or virtual has and run various assistance cases each. Each service runs at a notable port on at least one hosts.
