What exactly is Memcached? What is the reason for its increasing level of popularity among users who manage databases?
Memcached is a data caching system, which is used to accelerate the overall performance of database-powered websites by caching the queries and the replies between the visitor and the server. Simply put, every time a given page on such a site is requested, the script sends a database query to get the info that should be shown to the website visitor. If the latter clicks on a link to go to some other web page, the entire operation is repeated and this generates plenty of database queries and higher server load, especially if the website has lots of concurrent visitors. Memcached "memorizes" this information exchange, so in case any of these pages is requested again, the script no longer needs to call any info from the database, since everything is provided by the caching platform. In this way, the overall loading speed of your site will increase and you will have more satisfied visitors and they will be able to navigate through your website much faster. What’s more, the Memcached platform updates its cache if any content in the database is edited, so the visitors will never end up seeing out-of-date data.
Memcached in Shared Website Hosting
The Memcached content caching system is offered as an optional upgrade with each Linux shared website hosting plan
that we’re offering and you’ll be able to start using it as soon as you activate it, as the PHP extension that it needs so as to function correctly is pre-installed on our leading-edge cloud platform. You can request the upgrade from the Hepsia hosting Control Panel, which comes with each and every shared 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 websites that can use Memcached, while the second one, which is offered in increments of 16 megabytes, indicates the total size of the content that the system can cache. A busy site with a large database may need more memory to take an even greater advantage of Memcached, so if you want to upgrade this feature, you will be able to do it at any given time with several clicks.
Memcached in Semi-dedicated Servers
If you choose to host your Internet sites in a semi-dedicated server
account, you can take advantage of Memcached with ease, since the platform’s activation takes a few clicks of the mouse from the Hepsia Control Panel. The extension that it requires is pre-installed on our servers, so you can start using Memcached as soon as you add it to your semi-dedicated server account. You’ll be able to choose how many Internet sites can use it and how much info it will cache, in other words – there’re two separate features that can be upgraded – the number of instances and the amount of system memory. You can add more of both, so if one of your websites becomes very busy, for example, you can always add more memory to it. Our system is exceptionally flexible in this regard and we don’t bind a given number of instances to a fixed amount of system memory. You can take advantage of the Memcached caching platform to improve the speed of any script-driven Internet site, including those that are based on widely used Internet applications, such as WordPress or Joomla™
Memcached in VPS Servers
When you purchase a VPS server
from our company, you’ll be able to use Memcached at no additional charge, as the distributed memory object caching platform comes with all VPS servers ordered with the Hepsia hosting Control Panel. Even if you’ve got resource-hungry websites, you can optimize their performance effortlessly and the reduced load on the VPS server will permit you to keep using your current VPS hosting plan instead of moving to a more powerful one. The amount of memory that Memcached can use to store info depends on the plan that you’re using, but even with a lower-end one, you’ll have at least several hundred megabytes, which is significantly more than what you’d get with a shared plan, so the website performance boost will be immense. You can take advantage of Memcached with any database-powered web application, irrespective of whether you have built it yourself or you are using a ready-to-use one like OpenCart, WordPress or Joomla™
Memcached in Dedicated Servers
If you get one of our dedicated web hosting plans
and if you pick Hepsia as your website hosting Control Panel on the order form, you will get the Memcached distributed memory object caching platform as standard and you can set it up for any Internet site that you host on the dedicated server without installing or upgrading anything. It will begin caching info as users access your site, so you will detect the result of using it shortly thereafter. The minimum amount of system memory that will be available to the platform is 3 GB and naturally, the more powerful the dedicate server plan, the more memory Memcached will have at its disposal. This amount will allow you to use the platform for a large number of sites or for a very popular site without weakening its effectiveness. The Memcached caching platform will allow you to increase the speed of any database-powered site very quickly – a Joomla™
portal, a WordPress personal diary, an OpenCart web store, etc., and to boost the performance of your dedicated machine.
