What recommendations would you give when developing a system based on microservice architecture?

When developing a system based on microservices architecture, the following recommendations should be considered:

• Responsibility separation: each microservice should be responsible for a specific business function to minimize coupling.
• Independent deployment: microservices should be autonomous to allow for updates and scaling independently.
• Communication via API: use well-defined interfaces (REST, gRPC, etc.) for interaction between services.
• Error handling and fault tolerance: implement retry mechanisms, timeouts, circuit breakers to enhance reliability.
• Monitoring and logging: centralized collection of logs and metrics helps quickly identify and resolve issues.
• Configuration management: use centralized configuration services for easier parameter management.
• Security: ensure authentication and authorization between services.
• Automation: set up CI/CD for fast and secure delivery of changes.

In PHP, frameworks and tools supporting microservices, such as Symfony with API Platform, as well as containerization (Docker) and orchestration (Kubernetes), can be used to manage services.
