π 1. Real-World Context
Imagine DevSync grew massively π
- 10,000+ students taking courses daily
- 100+ mentors uploading content
- 1,000+ payments/hour
- Separate teams:
auth, course, payment, chat
Your monolithic backend now has:
- 50K+ lines of TypeScript
- 10 engineers pushing daily commits
- CI/CD taking 30 minutes per deployment
- Sometimes, small changes break other modules
This is the pain point that triggers the move.
π£ Why Monolith Starts to Break (Detailed View)
π§© 1. Tight Coupling & Low Agility
In a monolith:
- All modules share the same memory, database, and codebase.
- If you change something in the course module (e.g. schema change), it might break payments.
- Everyone depends on everyone. You canβt deploy independently.
