• Question 113:

  What benefits can a microservices architecture bring?

  A. The boundaries of service modules are clearer: microservices emphasize modular structure (REST interface calls), which is very important for large teams.
  B. Support for independent deployment: Simple services are easier to deploy. Because services are autonomous, they do not cause system crashes if problems occur.
  C. Simple operation and maintenance: Stateless, self-service operation and maintenance eliminates the need for a mature operation and maintenance team (mechanism), which greatly saves costs.
  D. Allow technology diversity: With microservices, you can mix multiple programming languages and develop frameworks And data storage technology.
