• Question 16:

  What benefits can a microservices architecture bring? () [Multiple choice questions]

  A. The boundaries of service modules are clearer: microservices emphasize modular structure (REST interface calls). This is very important for large teams Yes.
  B. Support for independent deployment: simple services are easier to deploy. Since the services are autonomous, there will be no systemcrash after a problem occurs.
