Memcached is a distributed memory caching platform, which is used to increase the loading speed of database-powered sites by caching the requests and the replies between the website visitor and the server. Put simply, anytime a particular web page on such a website is opened, the script connects to its database to fetch the info that should be shown to the visitor. In case the latter clicks a hyperlink to go to a different page, the whole process is carried out again and this leads to plenty of database queries and high load on the server, particularly if the website has lots of concurrent visitors. Memcached "memorizes" this exchange of information, so if any of these pages is accessed again, the script no longer needs to request any content from the database, as everything is provided by the Memcached platform. Thus, the overall load speed of your site will increase and you’ll have more happy visitors and they will be able to browse your site faster. Also, the Memcached platform "refreshes" its cache when any data in the database is edited, so the users will never end up seeing out-of-date content.
Memcached in Cloud Web Hosting
The Memcached object caching system comes as an optional upgrade with each and every Linux cloud web hosting offered by us and you will be able to start using it once you add it, since the PHP extension that it requires so as to work correctly is already available on our innovative cloud web hosting platform. You can order the upgrade through the Hepsia Control Panel, which is available with each web hosting package and a brand new Control Panel section where you can administer Memcached will show up. The upgrade is subdivided into two parts – the instances and the amount of memory, so as to offer you more flexibility. The first one refers to the number of the sites which can use Memcached, while the second, which comes in increments of 16 MB, specifies the total size of the content that the system can cache. A traffic-heavy Internet site with a very large database may need more memory in order to take an even bigger advantage of Memcached, so if you need to upgrade this service, you will be able to do it at any given moment with a couple of mouse clicks.
