The Dark Side of Microservices Nobody Talks About

Everyone's jumping on the microservices bandwagon. But after migrating 3 monoliths, here's what they don't tell you. 😱 The Hidden Costs 1. Debugging is 10x Harder In microservices you need distributed tracing (Jaeger), centralized logging (ELK), and correlation IDs. That's 3 new systems just to debug. 2. Data Consistency Nightmare Saga patterns, eventual consistency, compensating transactions - what was a simple DB transaction becomes distributed choreography. 3. DevOps Complexity Explodes Monolith Microservices 1 deployment 15+ deployments 1 database 15+ databases Simple CI/CD Complex pipelines 4. Team Coordination Overhead API contract changes: RFC + version negotiation + backward compatibility. 1 PR becomes 2 weeks of meetings. ✅ When Microservices Make Sense Team > 50 devs, different scaling needs, independent deployment critical ❌ When to Stay Monolith Team < 20, building v1, scale doesn't require it 🎯 The Middle Ground: Modular Monolith Start monolith -> Modularize -> Extract onl
