Scaling Reads

Read-heavy systems — read replicas, caching layers, CDN strategies, denormalization, and the patterns that let systems serve millions of reads per second.

Replication & Caching

Scale read-heavy systems with read replicas, multi-level caching, and CDN for static assets. Learn how to push reads as far from the database as possible.
