What technical or organizational problems have you encountered when developing a microservices architecture?

When developing a microservices architecture, I often encountered the following issues:

• Complexity of service interaction: designing APIs, protocols, error handling, and timeouts.
• State and data management: how to ensure data consistency, especially in distributed transactions.
• Monitoring and logging: having centralized log and metric collection for quick problem detection.
• Orchestration and deployment: setting up CI/CD, managing service versions.
• Organizational questions: dividing responsibilities between teams, coordinating changes.

For example, when integrating multiple microservices, delays and network errors occurred, which required implementing retries and a Circuit Breaker scheme.
