Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any Internet site, sometimes even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the server and to enhance the browsing speed for the site visitors. Whenever a visitor opens a page on a specific Internet site, the web browser request is processed by the web server and the requested data is served as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and in case any of them is accessed for a second time, it’s fetched by Varnish and not by the server directly. The boost in the overall performance comes from the fact that the accelerator processes the web requests substantially quicker than any web server, which results in much faster browsing speeds for the visitors. In case any content is updated in the meantime, the cached pages will also be updated the next time someone attempts to access them.

Varnish in Cloud Hosting

You can take advantage of Varnish’s full potential and optimize your sites’ load speed regardless of the cloud hosting package that you’ve chosen and you can enable and set up the data caching platform with a couple of mouse clicks through the simple-to-use GUI offered by our avant-garde Hepsia Control Panel. During the process, you will be able to choose two different things – how many sites will use Varnish, i.e. the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter comes in increments of 32 MB and is not linked to the number of instances, so you can add more instances and less memory and vice versa. In case you’ve got plenty of content on a given website and you gain plenty of visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. Hepsia will provide you with easy one-click buttons for deactivating or rebooting any instance, for deleting the cache associated with each site and for viewing comprehensive logs.
