@tank/system-design
by tankpkg
Practical system design for production distributed systems. Covers scalability patterns (load balancing, horizontal scaling, CDN, auto-scaling), data layer design (database selection, replication, sharding, consistency models, CAP theorem applied), caching strategies (cache-aside, write-through, invalidation, stampede prevention), messaging and async patterns (queues vs streams, event-driven architecture, CQRS, saga pattern, delivery guarantees), reliability (circuit breakers, bulkheads, retries, rate limiting, timeouts, chaos engineering), service architecture (monolith vs microservices, API gateway, service mesh, distributed transactions), and capacity planning (back-of-envelope estimation, SLOs/SLIs, monitoring, distributed tracing). Synthesizes Kleppmann (Designing Data-Intensive Applications), Vitillo (Understanding Distributed Systems), Newman (Building Microservices), Ford et al. (Software Architecture: The Hard Parts), Nygard (Release It!), Petrov (Database Internals), Richards & Ford (Fundamentals of Software Architecture), and Beyer et al. (Site Reliability Engineering).
