Microservices (MS) is an architecture pattern that prescribes to divide an application based on business functionality instead of technical boundaries.  These set of smaller interconnected services constitute the complete application. As opposed to monolithic architecture, it recommends breaking the application into smaller atomic units, each performing a single function.

Typically, an application provides a set of distinct features or functionality, such as order management, billing, customer service, ETC. Each microservice WORKS as a mini-application that has its own hexagonal architecture. It is often compared to Honeycombs (nests) that are a combination of MULTIPLE hexagonal structures.

Below are some of the key features of Microservices that distinguish from monolithic:

1. Tight Cohesion: Single responsibility per service i.e. code perform a single and well-defined task only.
2. Loose Coupling: Microservices are the autonomous i.e. effect of changes are isolated to that particular MS only.
3. Interoperability: One of the key foci of microservices is on communication between systems using diverse technologies.
4. Stateless: An ideal microservice does not have a state i.e. it does not store any information between requests. All the information needed to CREATE a response is present in the request.
5. Devops: It is highly recommended to implement an automated build and release process using suitable CI-CD infrastructure.
6. Developing Products instead of PROJECTS.
