Seven Microservices Anti-Patterns — One common mistake people made with SOA was misunderstanding how to achieve the reusability of services. Teams mostly focused on technical cohesion rather than functional regarding reusability.

This created an artificial physical layer managed by a horizontal team, which caused delivery dependency. Any service created should be highly autonomous – meaning independent of each other.
