Memcached is a distributed memory caching system, which is used to supercharge the load speed of database-powered Internet sites by caching the requests and the responses between the user and the server. To put it in simple terms, anytime a given web page on such a website is requested, the script sends a database query to request the information that should be displayed to the website visitor. In case the latter clicks on a link to visit another web page, the entire process is performed again and this generates lots of database requests and high load on the server, even more so if the website has lots of concurrent visitors. Memcached "memorizes" this information exchange, so in case any of these pages is requested again, the script no longer needs to request any data from the database, as everything is delivered by the caching platform. Thus, the overall load speed of your website will increase and you will enjoy more satisfied visitors and they’ll be able to browse your website much faster. At the same time, the Memcached platform updates its cache whenever any data in the database is altered, so the site visitors will never see outdated content.
Memcached in Cloud Hosting
The Memcached object caching system comes as an upgrade with every Linux cloud plan offered by us and you can begin using it the moment you enable it, as the extension that it requires in order to run properly is already available on our cutting-edge cloud website hosting platform. You can request the upgrade through the Hepsia Control Panel, which comes with each hosting package and a brand-new section where you can administer Memcached will appear. The upgrade is divided into two parts – the number of instances and the system memory, so as to give you more freedom. The first one shows the number of the Internet sites that can use Memcached, whereas the second one, which is offered in increments of 16 MB, defines the total size of the content that can be cached by the system. A popular site with a large-sized database may need more memory in order to take an even bigger advantage of the Memcached caching system, so in case you want to upgrade this feature, you will be able to do it at any given time with a few mouse clicks.
