What potential disadvantages may arise when transitioning to a microservices architecture?

Answer from AI
- Management and operational complexity: Distributing functionality across multiple independent services increases the complexity of monitoring, deployment, debugging, and infrastructure management.
- Testing: Increased testing complexity due to the need to test interactions between multiple services, not just individual components. Strategies for integration, end-to-end, and contract testing are required.
- Network latency and reliability: Interaction between services occurs over the network, which can cause delays and failures. Error handling mechanisms, retries, timeouts, and circuit breakers need to be implemented.
- Distributed transactions: Implementing business transactions that span multiple services becomes a complex task and requires patterns like Saga.
- Data consistency: Maintaining data consistency between independent services, possibly using different databases.
- Operational costs: Increased expenses for infrastructure, monitoring, logging, and staff training.
- Inter-service communication: Choosing the right protocols and mechanisms for interaction (REST, gRPC, asynchronous messaging via brokers).
- Code and dependency duplication: Possibility of duplicating common components or libraries across different services.
- API versioning complexity: Managing API changes and ensuring backward compatibility between services.
- Need for a strong DevOps organizational culture: Successful transition requires changes in team processes and culture, moving towards more autonomous cross-functional teams.
