Monolith Decomposition Strategy Unclear
You know the monolith needs to be broken up, but where do you cut? Extracting the wrong service first creates more coupling, not less. Without a clear domain understanding, you end up with a distributed monolith — all the complexity of microservices with none of the benefits.
🖇️
Services Too Tightly Coupled Despite Being "Micro"
Your services cannot be deployed independently. Changing one service requires coordinated changes in three others. Shared databases, synchronous call chains, and leaked domain concepts mean you built distributed code, not independent services.
📊
Distributed Transactions Causing Data Inconsistency
An order was created but payment was not recorded. A user's profile was updated in one service but the old data shows in another. Without a proper distributed data strategy, partial failures leave your system in inconsistent states that are painful to detect and fix.
📡
Service-to-Service Communication Overhead
Every request fans out into dozens of inter-service calls. Latency adds up, timeout settings are wrong, and one slow service cascades failures across the entire system. Your p99 latency is dominated by network hops, not business logic.
🧪
Testing Across Service Boundaries Is Painful
Unit tests pass but integration tests are flaky. Setting up a local environment with all dependencies running is nearly impossible. Contract testing is not in place, so API changes break consumers in production instead of in CI.
🚀
Deployment Complexity Growing Unmanageable
Deploying one feature requires releasing four services in the right order. Rollback affects the wrong version of a downstream service. Your release process has become a coordination nightmare that slows down delivery instead of enabling it.
