Memcached is a memory caching platform, which is used to improve the overall performance of database-powered sites by caching the queries and the responses between the visitor and the server. To put it simply, every time a certain web page on such a website is opened, the script queries its database to fetch the info that should be shown to the visitor. If the latter clicks on a hyperlink to visit a different web page, the entire operation is carried out again and this leads to a lot of database calls and high server load, even more so if the site has a lot of concurrent visitors. Memcached "remembers" this information exchange, so in case any of these web pages is opened again, the script no longer has to call any info from the database, since everything is provided by the caching platform. In this way, the overall speed of your website will "soar" and you will have more happy visitors and they’ll be able to navigate through your website faster. Additionally, the Memcached platform updates its cache when any info in the database is changed, so the site users will never end up seeing old data.
Memcached in Cloud Hosting
When you host script-powered websites in a cloud hosting account with our company, you’ll be able to add the Memcached distributed memory caching system to your web hosting package with only a few clicks of the mouse through your Hepsia Control Panel. The upgrade will be available immediately and, since the PHP extension needed for it is already installed on our cutting-edge cloud website hosting platform, you can begin using it right away. To give you more flexibility, we offer two separate upgrades related to the number of instances (in other words – how many websites will use Memcached) and to the system memory that the Memcached caching system will use. The latter is available in increments of 16 MB and you can order memory as many times as you need. Naturally, the more memory the Memcached caching system is allowed to use, the more data it will cache, so if you have a resource-hungry site with lots of data, you may need more memory so as to be able to take full advantage of the power that Memcached can give you.
