What precisely is Memcached? What is the reason for its growing popularity among users who manage databases?
Memcached is a distributed memory object caching platform, which is used to improve the performance of database-powered Internet sites by caching the queries and the replies between the visitor and the server. To put it in simple terms, every time a specific web page on such a website is opened, the script sends a query to its database to fetch the info that should be shown to the website visitor. If the latter clicks a hyperlink to go to some other web page, the entire operation is performed again and this leads to multiple database requests and excessive load on the server, even more so if the website has lots of concurrent visitors. Memcached "remembers" this information exchange, so in case any of these pages is visited again, the script no longer needs to cull any data from the database, as everything is provided by the Memcached platform. In this way, the overall load speed of your website will "soar" and you will get more pleased visitors and they will be able to browse your website faster. Besides, Memcached updates its cache when any content in the database is edited, so the visitors will never end up seeing outdated data.
Memcached in Shared Hosting
If you host script-powered websites in a shared hosting
account with us, you’ll be able to add Memcached to your shared web hosting package with just a few clicks of the mouse through your Hepsia hosting Control Panel. The upgrade will be available immediately and, since the PHP extension needed for it is pre-installed on our cutting-edge cloud hosting platform, you can start using it right away. To give you more versatility, we offer two different upgrades related to the number of instances (i.e. how many sites will use Memcached) and to the amount of memory that the Memcached caching system will use. The latter is available in increments of 16 megabytes and you can add memory whenever you want. Naturally, the more memory Memcached is permitted to use, the more data it will cache, so if you run a frequently visited site with lots of data, you may need more memory in order to be able to take advantage of the power that Memcached can give you.
Memcached in Semi-dedicated Servers
If you decide to host your sites in a semi-dedicated server
account, you can take advantage of Memcached easily, as the caching platform’s setup takes several clicks of the mouse from the Hepsia hosting Control Panel. The required extension is already installed on our servers, so you can begin using Memcached the moment you add it to your account. You will be able to select how many Internet sites can use it and how much data it will cache, i.e. there are two separate features that can be upgraded – the number of instances and the amount of system memory. You can get more of both, so if one of your Internet sites becomes extremely popular, for instance, you can always order more memory. Our system is extremely flexible in this regard and we don’t tie a given number of instances to a fixed amount of system memory. You can employ Memcached to increase the speed of any script-driven Internet site, including those based on widely used software applications, such as Joomla™
Memcached in VPS Servers
If you acquire a VPS server
from our company, you’ll be able to use Memcached at no extra cost, as the caching platform is offered with all servers ordered with the Hepsia Control Panel. Even if you have large websites, you will be able to boost their overall performance with no effort and the decreased load on the VPS server will permit you to continue using your current Virtual Private Server hosting package rather than upgrading to a more powerful one. The amount of memory that the Memcached platform can use to store info depends on the plan that you’re using, but even with a lower-end one, you will get at least several hundred megabytes, which is considerably more than the amount of memory you’d get with a shared package, so the website performance boost will be significant. You can take advantage of Memcached with any database-driven app, no matter if you have created it on your own or you’re using a ready-to-use one like Joomla™
, WordPress or OpenCart.
Memcached in Dedicated Servers
Each dedicated server
that is ordered with our Hepsia hosting Control Panel comes with Memcached already installed by default, so you can begin using this content caching system as soon as your dedicated server is fully operational, without having to upgrade or install anything. The amount of memory that Memcached can employ depends on the server that you’ve selected, but since our servers are amazingly powerful and due to the fact that it’s likely that you will host resource-requiring Internet sites on them, the minimum amount of memory that the system can use will be 3 gigabytes. This will allow you to enhance the overall performance of very busy sites effortlessly and you will notice the difference shortly after the Memcached system starts caching database calls. You can make full use of the system with any database-powered web page, including those that are based on widely used CMSs such as Joomla™
