What anti-patterns in microservice architecture do you know?

In microservices architecture, there are several common anti-patterns that can lead to issues with scalability, maintainability, and performance:

• Monolith within microservices — when services are too large and contain a lot of functionality, essentially turning into mini-monoliths.
• Tight Coupling — when microservices are heavily dependent on each other, complicating independent development and deployment.
• Synchronous calls between services — excessive use of synchronous requests leads to delays and reduced fault tolerance.
• Lack of centralized logging and monitoring — complicates diagnosis and debugging.
• Incorrect data management — when multiple services directly access the same database, violating the isolation principle.
• A large number of small services without clear necessity — complicates infrastructure and management.

Avoiding these anti-patterns can help build a more resilient and scalable system.
