What exactly is Memcached? What is the reason for its increasing popularity among users who maintain databases?
Memcached is a content caching system, which is used to optimize the performance of database-powered websites by caching the calls and the replies between the website visitor and the server. In other words, anytime a certain web page on such a website is accessed, the script sends a query to its database to get the information that should be displayed to the website visitor. In case the latter clicks a hyperlink to open another page, the entire procedure is repeated and this results in a lot of database queries and high server load, especially if the site has lots of simultaneous visitors. Memcached "remembers" this exchange of information, so if any of these web pages is accessed again, the script no longer needs to request any info from the database, since everything is provided by the caching platform. In this way, the overall load speed of your site will "soar" and you’ll have more pleased visitors and they will be able to navigate through your website faster. Plus, Memcached "refreshes" its cache every time any information in the database is altered, so the website visitors will never wind up seeing outdated content.
Memcached in Web Hosting
The Memcached content caching system is offered as an optional upgrade with each and every Linux web hosting package
that we’re offering and you can begin using it once you order it, as the extension that it requires so as to work correctly is already installed on our avant-garde cloud hosting platform. You can request the upgrade via the Hepsia Control Panel, which comes with each shared web hosting package and a brand-new section where you can administer Memcached will show up. The upgrade is separated into two parts – the number of instances and the amount of system memory, so as to offer you more versatility. The first one refers to the number of the websites which can use the Memcached caching system, whereas the second, which comes in increments of 16 MB, defines the maximum size of the content that the system can cache. A busy Internet site with a large-size database may require more memory so as to take an even bigger advantage of the Memcached caching system, so in case you wish to upgrade this feature, you will be able to do it at any given time with a couple of mouse clicks.
Memcached in Semi-dedicated Hosting
You can add the Memcached distributed memory caching platform to any of the Linux semi-dedicated hosting packages
offered by us and use its full potential for any script-powered Internet site hosted by us. The upgrade is offered through the Hepsia Control Panel and you can select two features – the number of instances and the amount of memory. These things define the number of the websites that can use Memcached and how much memory it will use to cache your content. You can choose them independently, since one instance is not bound to a fixed amount of system memory, so you can use a lot of memory for a single resource-requiring site, for example. This upgrade comes in increments of 16 MB and you can order as much memory as you wish. The Memcached platform can be used with any script-driven site irrespective of its nature, including those based on widely used applications like Joomla™
, WordPress or Drupal™
, and many companies like Wikipedia and Zynga are already using it to accelerate the performance of their sites.
Memcached in Dedicated Hosting
You can unleash the full potential of Memcached with each and every dedicated server
that we’re offering if you select Hepsia as your Control Panel. A special Control Panel section is dedicated to the caching system and you can start using Memcached for any Internet site hosted on the machine with only several mouse clicks. You can increase the performance of any website, no matter what script-based app you’re using or how popular the Internet site is, since the minimum amount of memory that Memcached will be able to employ is three gigabytes and this amount rises enormously with the more powerful dedicated servers. Shortly after the system is enabled, it will begin caching info each time someone browses your website, so, once enough data has been stored, you will distinguish the reduced load on your server and the enhanced overall performance of the Internet site. The Memcached caching system is being used by lots of sites, including popular portals like Wikipedia, Zynga and Reddit, which is an evidence of the effectiveness of the caching system.
