Varnish is a web app accelerator platform, which caches info for quicker access. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and its users. When a site visitor loads a particular webpage, its content is requested by the Internet browser, and then the web server handles this browser request and returns the needed info. If Varnish is activated for a certain site, it will cache the pages on the very first request and if the visitor accesses a cached page once more, the content will be delivered by the caching platform and not by the server. The boosted loading speed is an end result of the significantly faster response time that Varnish offers as compared to any web server software. Of course, this does not mean that the site visitors will keep being served the exact same content over and over again, as any modification on any of the pages is reflected in the content that Varnish caches in its system memory.

Varnish in Cloud Hosting

If you host your websites in a cloud hosting account with us, you’ll be able to activate Varnish with several clicks of the mouse through your Control Panel. The content caching platform comes as an upgrade with all our web hosting packages and you can select the number of the sites that will use it and the maximum storage space that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t tied directly to each other, so you can choose whether you need a lot of memory for one large-sized site or less memory for multiple smaller ones. You can make use of the full potential of Varnish in case the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/remove an instance, clear the cached data individually for each website that uses the Varnish platform or view an elaborate log.
