Modern Java EE Design Patterns

Appendix A. Additional Technologies and Team Considerations

As already mentioned, software architecture does not adhere to a strict process for creation. However, what it does involve is a lot of teamwork, creativity, and flexibility in adopting changing requirements. This not only covers the design of the system or individual services, but also reaches out to the technologies used and various team dynamics. Unlike with traditional Java EE applications, where the infrastructure is well defined by the application server in use, the solution space for microservices-based systems is open ended and requires a different perspective on teams.

This appendix is designed to point you to alternative microservices solutions outside of the traditional Java EE ecosystem. It also provides greater insight into aligning teams to work with highly scalable architectures.

Architecture != Implementation

Approaches to architectural design do not contain an implicit method for implementation. This is also true for microservices, although the service contracts in a microservices-based architecture allow for a flexible decision about the underlying implementation. It doesn’t even have to be on one platform or language.

If you are grounded in Java EE, you’ve already seen some recommendations and platform-specific thoughts for working with microservices. The basic metric used to compile this short list was that Java is the most commonly used programming language in today’s enterprises. To keep this a ...
