Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It is a web application accelerator that can increase the load speed of a website 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 accesses it again. Thus, the browser request from the visitor is not processed by the web server and the page will open considerably faster, since the Varnish platform can deliver information many times faster than any web server software. The result is a substantially faster loading website, which leads to a greatly improved website browsing experience. In case any of the cached pages is updated on the actual site, the data that Varnish saves in its memory is updated too, so the users will not see out-of-date info.

Varnish in Cloud Web Hosting

If you host your websites under a cloud web hosting account with us, you will be able to activate Varnish with a few mouse clicks through your Control Panel. The content caching platform is offered as an optional upgrade with all our web hosting packages and you can choose how many websites will use it and the total amount of system memory that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they are not directly linked to each other, so you can choose if you need plenty of memory for one single large-scale website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish platform in case the sites use a dedicated IP. With the Control Panel, you can easily start/restart/shut down an instance, delete the cached contents individually for each site which uses Varnish or see an in-depth system log file.
