Microservices is an architecture design model with a specific bounded context, configuration, and dependencies. These result from the architectural principles of the domain-driven design and DevOps. Domain-driven design is the idea of solving problems of the organization through code.

The business goal is important to the business users, with a clear interface and functions. This way, the microservice can run independently from other microservices. Moreover, the team can also work on it independently, which is, in fact, the point of the microservice architecture.

SOA is a design pattern in which multiple services combine to perform a certain tasks through different availble endpoints. The SOA emphasizes on reusing the code for different problems.

• Independent Deployability: This allow application to be loosely coupled and one application will be deployed without changing anything in the other service.

• Modeled around Business Domain:

  

Separating the business model will allow to make things easier, the domain of every business will be different so making change in one business domain will not effect the other.

• Owning their own State: Every Microservice should have their own state like if one service want to access the data from the other service it will require permissions from other service to allow access to the data, also it will keep the Object Oriented encapsulation principle alive of data hiding principle.
