What precisely is Memcached? What is the reason for its expanding popularity among people who manage databases?
Memcached is a distributed memory object caching system, which is used to accelerate the load speed of database-powered Internet sites by caching the requests and the replies between the visitor and the server. To put it in simple terms, anytime a particular page on such a site is visited, the script sends a query to its database to request the information that should be shown to the website visitor. If the latter clicks on a hyperlink to go to some other page, the entire operation is repeated and this generates lots of database calls and higher load on the server, particularly if the website has a lot of simultaneous visitors. Memcached "remembers" this information exchange, so if any of these web pages is visited again, the script no longer has to extract any content from the database, since everything is delivered by the caching platform. Thus, the overall load speed of your site will "soar" and you will enjoy more satisfied visitors and they’ll be able to browse your website faster. Also, Memcached "refreshes" its cache whenever any content in the database is modified, so the visitors will never end up seeing outdated data.
Memcached in Cloud Website Hosting
When you host script-powered sites in a cloud website hosting
account with our company, you will be able to add the Memcached distributed memory caching system to your hosting package with only a couple of mouse clicks through your Hepsia Control Panel. The upgrade will be available momentarily and, since the PHP extension required for it is pre-installed on our advanced cloud platform, you can start using it right away. To give you more flexibility, we offer two separate upgrades related to the number of instances (i.e. how many Internet sites will use Memcached) and to the amount of system memory that Memcached will use. The latter is available in increments of 16 megabytes and you can add memory as many times as you want. Logically, the more memory the Memcached caching system is allowed to use, the more data it will cache, so if you’ve got a traffic-intensive site with a lot of content, you may require more memory to be able to make the most of the power that Memcached can give you.
Memcached in Semi-dedicated Servers
In case you decide to host your websites in a semi-dedicated server
account, you’ll be able to take advantage of Memcached easily, as the memory caching platform’s setup takes a few clicks of the mouse from the Hepsia hosting Control Panel. The required extension is already installed on our semi-dedicated servers, so you can start using the Memcached caching platform the moment you add it to your semi-dedicated server account. You will be able to select how many websites can use it and how much content can be cached, in other words – there are two separate upgradable features – the instances and the amount of memory. You can get more of both, so if one of your Internet sites becomes very popular, for instance, you can always order more memory. Our system is rather flexible in this regard and we do not tie a given number of instances to a fixed amount of system memory. You can use the Memcached platform to improve the speed of any script-powered website, including those based on famous apps, such as Joomla™
Memcached in VPS Servers
Memcached comes as standard with all VPS hosting plans
ordered with our custom Hepsia Control Panel. The PHP extension it needs so as to function correctly is compiled when the Virtual Private Server is configured, so you can start using the distributed memory object caching platform the moment your brand-new virtual server is completely operational. The system memory that the Memcached platform can use depends on the given Virtual Private Server plan, but even with the low-end ones, you’ll get several hundred megabytes that will be at your disposal for this platform exclusively. This will allow you to increase the performance of multiple sites hosted on the server simultaneously and to lower the load even if you own content-rich script-powered web pages with a lot of viewers. The platform can be used with any script – Joomla™
or Mambo, or a custom-made script, and you will notice the faster performance shortly after you start using it.
Memcached in Dedicated Servers
Each dedicated server
that is ordered with our Hepsia Control Panel comes with Memcached pre-installed by default, so you can start using the caching system the moment the dedicated server is assembled, without needing to activate or upgrade anything. The amount of memory that Memcached can employ depends on the dedicated server that you’ve chosen, but since our servers are rather powerful and given the fact that it is likely that you will host resource-heavy websites on them, the minimum amount of memory that the system can use is 3 GB. This will enable you to increase the performance of very busy Internet sites without any effort and you’ll note the difference soon after Memcached starts caching database queries. You can take full advantage of the system with any database-powered site, including those based on widely used CMSs such as WordPress and Joomla™
