Varnish is a data caching platform, which is occasionally referred to as an HTTP reverse proxy. It is a website accelerator tool that can boost the speed of a website by up to one thousand percent, depending on the content itself. Anytime a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. In this way, the web browser request from the visitor is not processed by the server and the web page will open tremendously faster, since Varnish can deliver content many times faster than any server software. The end result is a much faster loading website, which means an improved browsing experience. In case any of the cached pages is updated on the live site, the content that Varnish saves in its system memory is ‘refreshed’ as well, so the site visitors won’t end up seeing old information.

Varnish in Cloud Hosting

If you host your Internet sites in a cloud hosting account with us, you will be able to activate Varnish with several clicks through your hosting Control Panel. The content caching platform is available as an upgrade with all our shared web hosting plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not linked directly to each other, so you can choose whether you want lots of memory for one large-scale site or less memory for multiple smaller ones. You can unleash the full potential of Varnish if the websites use a dedicated IP address. Using the Control Panel, you can easily start/restart/delete an instance, delete the cached files independently for each website that uses Varnish or see an in-depth log.
