What problems can we face when designing a microservices architecture?

The following problems may arise when designing a microservices architecture:

• Management complexity: a large number of services requires effective orchestration and monitoring.
• Network delays and reliability: interaction between services over the network increases response time and failure risks.
• Data consistency: distributed transactions are complex, and it is necessary to use eventual consistency and consider compensation strategies.
• API versioning: when updating services, it is important to maintain compatibility and avoid breaking changes.
• Security: authentication and authorization between services must be ensured.
• Testing and debugging: more difficult due to distribution, requiring specialized tools.

For example, to address reliability issues, patterns like Circuit Breaker and Retry are often used, and for configuration management, centralized configuration services are employed.
