Here are its main downsides: ### 1. **Complex infrastructure** Each service is a separate application with its own database, API, CI/CD, and monitoring. For dozens of services you need containerization, orchestration (Kubernetes), and a mature DevOps environment. ### 2. **Communication complexity** All interaction happens over the network. This brings latency, connection errors, and the need for retry mechanisms and distributed tracing. ### 3. **Complex testing** To verify one scenario, you need to spin up several services and their dependencies. Integration tests become expensive and fragile. ### 4. **Data management** Because of isolated databases, shared queries and transactions are hard to do. You have to use eventual consistency and events, which requires experience and discipline. ### 5. **Growing overhead** More code, configuration, logging, and duplicated logic make the system heavy for small teams. **Summary:** > Microservices suit large, distributed projects. > But without a mature architecture, DevOps, and team culture, they easily turn into chaos made of hundreds of small, poorly connected services.For the reviewerNote to the moderator (optional)Visible only to the moderator.
