Memcached
Memcached is an open-source, high-performance, distributed memory object caching system designed to speed up dynamic web applications by alleviating database load. It stores data and objects in RAM to reduce the number of times an external data source (like a database or API) must be read, significantly improving response times. A Memcached cluster refers to a group of Memcached servers working together to provide a scalable, fault-tolerant caching layer.
Developers should use Memcached clusters when building high-traffic web applications that require fast data access, such as e-commerce sites, social media platforms, or real-time analytics dashboards, to reduce latency and improve scalability. It's particularly useful for caching frequently accessed data like session information, database query results, or API responses, allowing applications to handle more concurrent users without overloading backend systems.
