Varnish is a web application accelerator platform, which caches info for the sake of faster access. It’s occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a website visitor opens a particular page, its content is requested by the Internet browser, and then the server processes this request and delivers the needed content. If Varnish is enabled for a given site, it will cache its pages at the first request and in case the user visits a cached page for a second time, the data will be delivered by the accelerator platform and not by the server. The accelerated load speed is an end result of the significantly faster response speed that Varnish offers compared to any web server software. At the same time, this does not mean that the users will keep seeing the very same content over and over again, because any update on any of the web pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Cloud Hosting

You can take advantage of Varnish’s potential and improve the loading speed of your sites irrespective of the cloud hosting plan that you’ve selected and you can activate and configure the content caching platform with a few clicks of the mouse through the intuitive graphical interface offered by our advanced Hepsia Control Panel. In the meantime, you’ll be able to select two separate things – how many sites will employ the Varnish caching platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter comes in increments of 32 MB and is not tied to the number of instances, so you can use more instances with less memory and the other way around. If you have plenty of content on a specific Internet site and you receive numerous website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP address for the websites that will use Varnish. The Hepsia Control Panel will offer you simple one-click controls for disabling or restarting any instance, for deleting the cache for any website and for seeing detailed logs.
