System Design¶
Patterns and case studies for designing systems that have to keep running. Sharding, replication, queues, caches — and the tradeoffs between them.
By experience level¶
-
Junior
Foundations: building blocks of distributed systems, scalability basics, and common architectural patterns every developer should know.
-
Middle
Mid-level depth: production patterns, caching strategies, message queues, database scaling, and observability fundamentals.
-
Senior
Senior mastery: high-availability patterns, consistency tradeoffs, distributed transactions, and complex system tradeoff analysis.
-
Professional
Production-grade: multi-region architectures, capacity planning, disaster recovery, and the hard parts of operating at scale.
