Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the loading speed of any Internet site, at times even by one hundred percent, based on the content itself. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to reduce the overall server load and to accelerate the browsing speed for the website visitors. Each time a visitor opens a page on a specific site, the web browser request is handled by the web server and the requested content is sent as a response. If Varnish is enabled, it caches the web pages that the website visitor browses and if any of them is loaded once more, it’s served by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the visitors. In case any content is changed in the meantime, the cached pages will also be updated the next time someone attempts to open them.
Varnish in Cloud Website Hosting
You can take advantage of Varnish’s full potential and accelerate the speed of your sites regardless of the cloud website hosting package that you’ve picked and you can activate and set up the data caching platform with a few mouse clicks using the intuitive graphical interface offered by our leading-edge Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many sites will use the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances with less memory and the other way around. In case you’ve got a lot of content on a particular site and you receive numerous visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy one-click controls for switching off or rebooting any instance, for clearing the cache for any Internet site and for seeing elaborate system logs.
