System Design for Web Engineers
About this course
System design interviews and real architecture decisions share the same skill: reasoning about trade-offs under constraints. This course covers databases, caching, message queues, load balancing, CDNs, rate limiting, and designing for failure.
What you will learn
- A framework for approaching system design questions
- Database selection: relational, document, graph, time-series
- Caching strategies and invalidation patterns
- Message queues and event streaming trade-offs
- Load balancing: L4 vs L7, health checks, and draining
- CDN and edge computing patterns
- Rate limiting and backpressure mechanisms
- Designing for failure: circuit breakers and chaos engineering
