System design is about assembling services using primitives like databases, caches, and queues. Good design looks underwhelming and focuses on minimizing stateful components, using databases effectively with proper indexing, handling slow operations through background jobs, implementing strategic caching, and designing for failure with retries and circuit breakers. The key is using boring, well-tested components correctly rather than clever tricks.
