Memcached is a memory caching system, which has been gaining popularity in recent years because of its effectiveness. It is used to cache requests and responses between a database and the application that is using it, which can increase the performance of your site and reduce the produced server load drastically. Every time a webpage on an application-driven site is accessed, the app connects to the database and "asks" what information should be shown, and then pulls it. With Memcached, these steps are skipped, since the platform has already cached all the content that should be displayed on a certain webpage. If any data is updated, the Memcached content is ‘refreshed’ too, so the website visitors will never end up seeing out-of-date data. The platform is an excellent solution for every site that attracts many viewers, as it will increase its loading speed and will improve the user experience.
