What exactly is Memcached? What is the reason for its rising level of popularity among people who take care of databases?
Memcached is an object caching system, which is used to enhance the overall performance of database-powered websites by caching the requests and the replies between the website visitor and the server. Simply put, every time a given page on such a website is requested, the script connects to its database to fetch the info that should be shown to the website visitor. If the latter clicks on a link to open some other page, the entire procedure is performed again and this leads to lots of database requests and excessive server load, particularly if the site has a lot of concurrent visitors. Memcached "remembers" this information exchange, so in case any of these web pages is accessed again, the script no longer needs to cull any information from the database, as everything is provided by the caching platform. Thus, the overall load speed of your site will "soar" and you’ll have more pleased visitors and they’ll be able to surf through your site faster. Plus, Memcached updates its cache when any content in the database is updated, so the site users will never wind up seeing out-of-date data.
Memcached in Cloud Hosting
If you host script-powered sites in a cloud hosting
account with us, you will be able to add the Memcached distributed memory caching system to your web hosting package with only a couple of clicks from your Hepsia hosting Control Panel. The upgrade will be available immediately and, since the extension required for it is pre-installed on our avant-garde cloud web hosting platform, you can begin using it right away. To give you more versatility, we offer two separate upgrades related to the number of instances (i.e. how many sites will use Memcached) and to the amount of system memory that Memcached will use. The latter is offered in increments of 16 MB and you can add as much memory as you wish. Logically, the more memory Memcached is permitted to use, the more data it will cache, so if you own a heavy-traffic site with a lot of content, you may require more memory so as to be able to make full use of the power that Memcached can offer you.
