Memcached

Memcached is an open-source, high-performance, distributed memory caching system. It's designed to speed up dynamic web applications by alleviating database load. Memcached achieves this by caching data and objects in RAM to reduce the number of times an external data source (like a database or API) must be read. Widely used in web hosting, it improves response times for data-driven websites by storing frequently accessed information for quick retrieval.
