What every Java engineer should know about microservices: Reactive Microservices Architecture.  Brought to you in partnership with Lightbend.

  1. You already know what ThreadLocal is (and used that extensively)
  2. You see transaction management in the application code (an annotation, however is not perfect, but o.k.)
  3. You have to deal with EntityManagerFactory and EntityTransaction in your code
  4. Your XML-configuration doesn't fit on a single page any more
  5. Your solution cannot be handled without extensive tooling
  6. You spend some time for convincing other developers, that your solution is actually lightweight :-)
  7. You are in the process of replacing existing frameworks with your "lightweight" POJOs and hope the result will be easier, lighter and better maintainable
  8. You forgot the name and purpose of the layers
  9. The number of interfaces is equal or greater, than the number of classes, and you need naming conventions to deal with that
  10. The deployment size of your application archive (WAR) is greater, than the installation size of your "lightweight" server (like tomcat)
