Memcached is a content caching system, which is used to supercharge the load speed of database-powered sites by caching the calls and the responses between the user and the server. Simply put, every time a particular web page on such a site is requested, the script connects to its database to fetch the info that should be displayed to the visitor. If the latter clicks on a hyperlink to visit a different web page, the whole process is executed again and this leads to a lot of database requests and higher server load, particularly if the site has lots of simultaneous visitors. Memcached "remembers" this information exchange, so in case any of these web pages is opened again, the script no longer has to request any info from the database, since everything is provided by the caching platform. In this way, the overall load speed of your website will "soar" and you will have more happy visitors and they will be able to navigate through your site much faster. Furthermore, the Memcached platform "refreshes" its cache whenever any content in the database is modified, so the visitors will never end up seeing outdated data.
Memcached in Cloud Hosting
You can make use of the Memcached data caching system with all cloud hosting that we’re offering. It is offered as an optional upgrade, which you can add with just a few clicks via your Hepsia web hosting Control Panel. It requires a PHP extension, which is pre-installed on our cloud hosting platform, so you can start using the Memcached caching system as soon as you order it. The upgrade is divided into two parts, which will offer you more versatility depending on the websites that you would like to use it for. The first one reveals the number of the websites that will use the Memcached caching system, or the so-called ‘instances’, whereas the second one is related to the memory, i.e. to how much content Memcached will be able to cache. You can order more memory in increments of 16 megabytes and the more memory you’ve got, the more content will be cached, which may be a good idea for heavy-traffic websites with large-sized databases and plenty of visitors. Thus, you can enhance the overall performance of any script-driven website hosted on our cloud servers without any effort.
