What are the benefits of the microservices architecture? (Multiple choice)

The boundaries of the service module are clearer: Microservices emphasize modular structure (REST interface calls), which is very important for large teams.

Support independent deployment: Simple services are easier to deploy, because the service is autonomous, and it will not cause a system crash after a problem occurs.

Simple operation and maintenance: stateless, self-service operation and maintenance make the system do not need a mature operation and maintenance team (mechanism). Significant cost savings

Allow for technical diversity: With microservices, you can mix multiple programming languages, development frameworks and data storage technologies.
