Memcached is a high performance, in-memory key-value store or caching system. Its main purpose is to speed up web applications by caching database queries, contents, or other computed results. Memcached is originally a linux application, but since it is open-source, it has been compiled for windows.

What is Memcached used for?

Memcached is an open source, distributed memory object caching system that alleviates database load to speed up dynamic Web applications. The system caches data and objects in memory to minimize the frequency with which an external database or API (application program interface) must be accessed.

Is Memcached safe?

Memcache vulnerabilities As open-source software, Memcached could be vulnerable to attacks. This became apparent in 2018 when a new form of DDoS attack was launched. Cyber attackers sent spoof requests, which mask the real identity of a sender by cloaking their IP address, to a vulnerable UDP Memcached server.
