What exactly is Memcached? What is the reason for its expanding recognition among people who manage databases?
Memcached is a distributed memory caching system, which is used to optimize the overall performance of database-driven websites by caching the queries and the replies between the website visitor and the server. To put it differently, anytime a certain page on such a site is visited, the script calls its database to fetch the info that should be displayed to the website visitor. In case the latter clicks on a hyperlink to visit some other web page, the whole operation is performed again and this generates numerous database requests and high server load, even more so if the website has a lot of concurrent visitors. Memcached "memorizes" this exchange of information, so in case any of these web pages is visited again, the script no longer needs to call any content from the database, as everything is provided by the caching platform. Thus, the overall load speed of your site will increase and you’ll enjoy more happy visitors and they’ll be able to navigate through your site faster. Moreover, the Memcached platform updates its cache if any content in the database is updated, so the visitors will never see old content.
Memcached in Shared Hosting
If you host script-driven websites in a shared hosting
account with us, you’ll be able to add the Memcached content caching system to your shared hosting plan with just a few mouse clicks via your Hepsia Control Panel. The upgrade will be available immediately and, since the extension needed for it is already installed on our innovative cloud web hosting platform, you can begin using it right away. To give you more flexibility, we offer two different upgrades related to the number of instances (i.e. how many Internet 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 need. Logically, the more memory the Memcached caching system is permitted to use, the more content it will cache, so in case you have a traffic-hungry website with a lot of content, you may require more memory 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 websites in a semi-dedicated server
account, you will be able to take advantage of Memcached easily, as the content caching platform’s activation requires several clicks of the mouse from the Hepsia hosting Control Panel. The required PHP extension is already installed on our servers, so you can begin using Memcached as soon as you add it to your semi-dedicated server account. You will be able to select how many Internet sites can use it and how much content can be cached, i.e. there’re two different features that can be upgraded – the instances and the memory. You can order more of both, so if one of your sites becomes extremely busy, for example, you can always add more memory to it. Our system is stunningly flexible in this regard and we don’t bind a specific number of instances to a pre-defined amount of system memory. You can employ Memcached to accelerate any script-powered Internet site, including those based on widely used web-based apps, such as WordPress or Joomla™
Memcached in Dedicated Servers
You can use the full potential of Memcached with every dedicated server
offered by us in case you choose Hepsia as your Control Panel. A special Control Panel section is dedicated to the distributed memory caching system and you can begin using Memcached for any Internet site hosted on the dedicated machine with only a couple of clicks of the mouse. You can enhance the performance of any site, irrespective of what script-driven software application you are using or how busy the Internet site is, since the minimum amount of memory that Memcached will be able to use is 3 gigabytes and this amount grows enormously with the higher-end servers. Soon after the system is enabled, it will start caching information each time someone visits your site, so, once enough information has been stored, you will distinguish the lowered server load and the optimized performance of your website. The Memcached caching system is used by many sites, among them popular portals such as Zynga, Wikipedia and Reddit, which verifies the efficiency of the caching system.
