Memcached is a distributed memory object caching platform, which is used to accelerate the speed of database-powered sites by caching the requests and the responses between the visitor and the server. In other words, every time a specific page on such a website is requested, the script queries its database to request the information that should be displayed to the visitor. In case the latter clicks a link to go to another web page, the entire process is repeated and this results in multiple database calls and higher load on the server, especially if the site has a lot of concurrent visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is visited again, the script no longer has to call any info from the database, since everything is provided by the caching platform. In this way, the overall speed of your site will "soar" and you’ll enjoy more gratified visitors and they’ll be able to browse your site faster. What’s more, the Memcached platform updates its cache every time any content in the database is changed, so the visitors will never wind up seeing out-of-date data.
Memcached in Cloud Hosting
The Memcached content caching system is offered as an upgrade with each cloud hosting that we’re offering and you can start using it as soon as you add it, as the PHP extension that it requires in order to function properly is already present on our avant-garde cloud web hosting platform. You can request the upgrade via the Hepsia hosting Control Panel, which comes with each plan and a brand-new section where you can manage Memcached will appear. The upgrade is separated into two parts – the instances and the system memory, so as to give you more flexibility. The first one refers to the number of the websites which can use Memcached, whereas the second one, which is offered in increments of 16 MB, indicates the total size of the content that can be cached by the system. A heavy-traffic site with a large database may need more memory so as to take an even bigger advantage of the Memcached caching system, so if you want to upgrade this feature, you’ll be able to do it at any moment with a couple of clicks.
