Latest Caching-Strategies Articles

Caching is one of the most effective techniques for improving performance, scalability, and availability in software systems. Instead of repeatedly fetching data from a slower source such as a database, API, object storage, or another service, a cache stores frequently used data in a faster layer.

Cache-aside, write-through, and write-behind define how applications coordinate cached data with authoritative storage. Each pattern changes read latency, write latency, consistency, durability, and failure recovery.
