Key Concepts to Master
A distributed hashing scheme that minimizes key remapping when nodes are added or removed.
A shared cache layer across multiple nodes used to absorb read traffic from the primary database and reduce latency on hot data paths. The difference between a 2ms and a 200ms read at scale.
Content Delivery Network. A geographically distributed network of edge servers that caches content close to end users, reducing origin server load and cutting time-to-first-byte by 50–200ms depending on user location.
Object storage for unstructured binary data: images, videos, documents, ML model weights. Designed for durability and throughput at scale, not low-latency random access.
