Varnish is a content caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It’s a website accelerator that can boost the speed of a site by up to 1000%, depending on its content. Every time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. In this way, the browser request from the visitor is not processed by the server and the web page will open considerably faster, since the Varnish caching platform can deliver content many times faster than any web server software. The result will be a considerably faster loading website, which means a much-improved visitor experience. When any of the cached pages is updated on the actual website, the content that Varnish caches in its system memory is ‘refreshed’ as well, so the visitors won’t end up seeing out-of-date data.

Varnish in Cloud Website Hosting

If you host your websites under a cloud website hosting account with us, you’ll be able to add Varnish with several clicks via your hosting Control Panel. The data caching platform comes as an optional upgrade with all our shared packages and you can choose the number of the sites that will use it and the maximum amount of system memory that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t linked directly to each other, so you can decide if you need lots of memory for a single large-scale website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish in case the websites use a dedicated IP. Using the Control Panel, you can swiftly start/reboot/shut down an instance, clear the cached files independently for each website which employs the Varnish platform or view an in-depth log.
