Memcached is a data caching system, which is used to boost the overall performance of database-driven Internet sites by caching the calls and the replies between the visitor and the server. To put it in simple terms, every time a certain page on such a website is visited, the script connects to its database to fetch the information that should be displayed to the website visitor. If the latter clicks on a link to open some other page, the entire process is repeated and this leads to lots of database requests and excessive load on the server, especially if the site has lots of simultaneous visitors. Memcached "memorizes" this exchange of information, so if any of these web pages is visited again, the script no longer has to request any information from the database, since everything is delivered by the caching platform. Thus, the overall speed of your site will increase and you will get more pleased visitors and they will be able to navigate through your website faster. Plus, Memcached updates its cache if any data in the database is modified, so the website visitors will never wind up seeing out-of-date content.
Memcached in Cloud Hosting
The Memcached distributed memory caching system is offered as an optional upgrade with each Linux cloud hosting package offered by our company and you’ll be able to begin using it as soon as you add it, since the extension that it requires in order to run correctly is already installed on our leading-edge cloud hosting platform. You can order the upgrade from the Hepsia Control Panel, which comes bundled with each hosting plan and a brand new section where you can administer Memcached will show up. The upgrade is subdivided into two parts – the number of instances and the system memory, so as to give you more flexibility. The first one shows the number of the sites that can use Memcached, whereas the second, which is available in increments of 16 MB, specifies the total size of the content that the system can cache. A traffic-intensive Internet site with a large-size database may need more memory so as to take an even bigger advantage of Memcached, so in case you would like to upgrade this service, you’ll be able to do it at any time with a few mouse clicks.
