CSE
System design practice
Work through system design scenarios one decision at a time. Each choice shows its trade-off, so you learn why a design works, not just what it looks like.
What you do here
Scenario-based decisions
Each scenario poses a real requirement and asks you to choose between designs, then shows what happens under load or failure.
Architecture diagrams
Every scenario draws its architecture, so the components and their connections are clear.
Topics covered
- Caching
- Database scaling and sharding
- Connection pooling
- Message queues
- Load balancing
- Distributed transactions and sagas
- Regional failover
- Consistency and availability
Questions
- Is this for beginners?
- The scenarios start with fundamentals like connection pooling and caching, then build up to multi-region designs.
