Example Concept: Distributed caching involves deploying cache nodes across multiple locations or nodes within a network, which store copies of data that are frequently requested. By doing so, applications can access data from the nearest cache node rather than querying the central database every time, significantly reducing data retrieval times and network congestion. This technique is often implemented using technologies like Redis, Memcached, or AWS ElastiCache, and is essential for applications requiring high throughput and low latency.
