What exactly is Memcached? What is the reason for its growing recognition among users who manage databases?
Memcached is a caching system, which is used to boost the speed of database-driven websites by caching the calls and the replies between the website visitor and the server. To put it in simple terms, every time a specific web page on such a site is visited, the script sends a database query to fetch the info that should be displayed to the website visitor. In case the latter clicks a link to open a different web page, the entire procedure is executed again and this generates lots of database requests and higher server load, particularly if the site has lots of concurrent visitors. Memcached "remembers" this information exchange, so if any of these web pages is accessed again, the script no longer needs to request any data from the database, as everything is delivered by the caching platform. In this way, the overall loading speed of your website will "soar" and you’ll have more pleased visitors and they will be able to navigate through your site much faster. Furthermore, the Memcached platform updates its cache when any content in the database is modified, so the site visitors will never wind up seeing outdated data.
Memcached in Hosting
The Memcached data caching system is offered as an optional upgrade with each Linux hosting
offered by us and you will be able to begin using it as soon as you order it, as the PHP extension that it needs in order to perform properly is already present on our avant-garde cloud hosting platform. You can order the upgrade via the Hepsia Control Panel, which is offered with each and every web hosting plan and a new section where you can manage Memcached will appear. The upgrade is separated into two parts – the instances and the amount of memory, so as to give you more flexibility. The first one shows the number of the Internet sites which can use Memcached, whereas the second, which is available in increments of 16 MB, determines the maximum size of the content that can be cached by the system. A traffic-heavy site with a large-sized database may require more memory in order to take an even greater advantage of the Memcached caching system, so if you would like to upgrade this service, you will be able to do it at any point with several clicks.
Memcached in VPS
Memcached comes by default with every virtual private server
that we’re offering on the condition that you choose Hepsia as your Control Panel, so you will not have to pay any extra cash to be able to take advantage of the full potential of this memory caching system. The more powerful Virtual Private Server package you select, the more memory Memcached will have for data storage purposes, but you will have at least several hundred megabytes at all times, which is much more than what you would get with a shared web hosting package. This will enable you to use the Memcached caching system for plenty of sites, no matter how popular they are, which in turn means that you can use a less powerful package for them without overloading the Virtual Private Server. The caching system is excellent for script-driven web apps like OpenCart, Joomla™
, WordPress or Mambo, and you can use it even with a custom-built app. Shortly after you enable Memcached, it will begin caching information and you will perceive the improved performance of your sites.
Memcached in Dedicated Hosting
Any dedicated server
that is ordered with our Hepsia Control Panel comes with Memcached already installed by default, so you can start using this caching system as soon as your server is assembled, without having to upgrade or install anything. The amount of memory that Memcached can use depends on the dedicated server that you’ve selected, but as our servers are remarkably powerful and due to the fact that it’s likely that you’ll host resource-hungry sites on them, the minimum amount of memory that the system can use will be three gigabytes. This will permit you to increase the performance of very heavy sites without any effort and you will note the difference soon after the Memcached caching system begins caching database queries. You can take advantage of the Memcached system with any database-powered web portal, including those based on widely used CMSs like WordPress and Joomla™
