Daily Term: Distributed Cache

Distributed Cache

A Distributed Cache spreads cached data across multiple servers to improve scalability and availability. For example, a web app might use a distributed cache like Redis Cluster to store user sessions across several nodes, ensuring no single point of failure. Distributed caches enhance performance in large-scale systems by distributing load, but they introduce complexity in managing data consistency and network latency between nodes.
