In other words: you’ll only understand it after you understand it. I didn’t like that response. I want documentation that takes me from an unproductive newbie to a somewhat functioning journeyperson.

Considerations for when—and when not—to apply microservices in your organization. Despite the drive in some quarters to make microservice architectures the default approach for software, I feel that due to their numerous challenges, adopting them still requires careful thought. You need to assess your problem space, your skills, technology landscape, and understand what you are trying to achieve before deciding if microservices are right for you.
