Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times even by 100%, based on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to accelerate the access speed for the website visitors. Anytime a visitor opens a page on a given site, the web browser request is processed by the web server and the requested content is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor browses and if any of them is loaded for a second time, it’s delivered by Varnish and not by the web server directly. The performance boost comes from the fact that the accelerator handles the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the site visitors. In case any content is updated meanwhile, the cached pages will also be updated the next time someone attempts to open them.

Varnish in Cloud Web Hosting

You can unlock Varnish’s full potential and improve the load speed of your websites regardless of the cloud web hosting plan that you have chosen and you can activate and configure the data caching platform with a couple of mouse clicks from the easy-to-use GUI offered by our leading-edge Hepsia Control Panel. During the process, you’ll be able to choose two separate things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can use more instances with less memory and the other way around. In case you have lots of content on a particular site and you draw a lot of website 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. The Hepsia Control Panel will offer you easy 1-click buttons for shutting down or restarting any instance, for erasing the cache for any Internet site and for seeing comprehensive system logs.
