What exactly is Memcached? What is the reason for its growing recognition among people who maintain databases?
Memcached is a distributed memory object caching platform, which is used to increase the loading speed of database-driven sites by caching the requests and the responses between the visitor and the server. To put it in simple terms, anytime a certain page on such a website is requested, the script sends a database query to get the information that should be displayed to the website visitor. In case the latter clicks a link to open a different page, the entire operation is performed again and this results in numerous database requests and higher server load, particularly if the site has lots of concurrent visitors. Memcached "remembers" this exchange of information, so in case any of these pages is accessed again, the script no longer needs to cull any info from the database, since everything is delivered by the Memcached platform. In this way, the overall loading speed of your site will increase and you’ll have more pleased visitors and they’ll be able to navigate through your site faster. Moreover, Memcached "refreshes" its cache if any information in the database is updated, so the visitors will never end up seeing outdated content.
Memcached in Cloud Hosting
You can make use of Memcached with all cloud hosting
offered by us. It is offered as an optional upgrade, which you can obtain with only a few mouse clicks from your Hepsia hosting Control Panel. It requires a PHP extension, which is already installed on our cloud web hosting platform, so you can begin using the Memcached caching system as soon as you add it. The upgrade is divided into two parts, which will give you more freedom depending on the Internet sites that you would like to use it for. The first part reveals the number of the websites that will use Memcached, or the ‘instances’, while the second one is related to the system memory, in other words – to how much content the system will be able to cache. You can order more system memory in increments of 16 MB and the more memory you’ve got, the more content will be cached, which may be an exceptionally good idea for high-demand sites with large-size databases and lots of users. Thus, you can increase the speed of any script-powered site hosted on our cloud servers without any efforts.
Memcached in Semi-dedicated Servers
You can get the Memcached memory caching system as an upgrade with all our semi-dedicated servers
and since it works with any script-based app, you can use it for any website that you host on our servers, regardless of what application you have used – WordPress, Joomla™
or Mambo, a custom-built application, etc. You can add the upgrade through the corresponding section of the Hepsia Control Panel from which you manage your semi-dedicated account, and you can select two separate features – the instances and the amount of system memory that they will use. In simple terms, these things indicate how many sites will use the Memcached system and the maximum amount of memory that the system will be able to use in order to cache your data. The two things are offered separately for more freedom and one instance does not come with a fixed amount of system memory. You can make use of Memcached with any sort of site and both you and the visitors will quickly distinguish the difference in the performance.
Memcached in VPS Servers
You will get Memcached with each of the VPS server
packages offered by us when you pick Hepsia as your Control Panel and you’ll be able to activate the memory caching platform through the Control Panel section with the exact same name. The configuration requires several clicks and you will notice the difference in the overall performance of your websites almost instantaneously. The amount of system memory that the Memcached platform can take advantage of to store data depends on the particular Virtual Private Server hosting plan that you have chosen, but in any case it won’t be less than several hundred megabytes, which is quite enough even for multiple large sites. You can use the Memcached platform with sites driven by Joomla™
, WordPress or any other web app and reduce the load on your Virtual Private Server, which will enable you to continue using the current VPS hosting package instead of switching to a more powerful one, as you will simply not need it. Memcached is already being used by popular websites like Wikipedia, Zynga and Reddit, which is an evidence of its efficiency.
Memcached in Dedicated Servers
Each dedicated server
ordered with our Hepsia hosting Control Panel comes with Memcached pre-installed by default, so you can begin using the caching system as soon as your server is completely functional, without needing to install or upgrade anything. The amount of system memory that Memcached can employ depends on the very server that you have selected, but as our servers are exceptionally powerful and considering the fact that it’s likely that you’ll host resource-hungry websites on them, the minimum amount of memory that the caching system can use is 3 gigabytes. This will enable you to improve the performance of very popular websites without any effort and you will observe the difference soon after the Memcached caching system starts caching database requests. You can make use of the system with any database-driven web portal, including those that are based on popular CMSs like Joomla™
