Varnish is a web app accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any site, at times even by one hundred percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to enhance the browsing speed for the website visitors. Each time a visitor opens a page on a certain website, the browser request is handled by the web server and the requested data is sent as a reply. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and if any of them is accessed again, it’s served by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests substantially faster than any web server, which leads to much faster browsing speeds for the site visitors. If any content is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody attempts to open them.

Varnish in Cloud Hosting

You can unlock Varnish’s potential and speed up your websites regardless of the cloud hosting package that you have chosen and you can enable and set up the data caching platform with a few clicks using the user-friendly GUI offered by our cutting-edge Hepsia hosting Control Panel. During the procedure, you will be able to select two different things – how many sites will employ the Varnish platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances and less memory and vice versa. In case you have a lot of content on a particular Internet site and you win many site visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP address for the sites that will use Varnish. Hepsia will offer you simple 1-click controls for deleting or rebooting any instance, for erasing the cache for any website and for seeing detailed system logs.
