Varnish is a web application accelerator platform, which caches info for quicker access. It is sometimes called an HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a visitor accesses a given web page, the content is requested by the browser, and then the web server handles this browser request and sends back the required information. If Varnish is activated for a specific site, it will cache its pages at the first visit and if the user opens a cached page once again, the content will be delivered by the accelerator platform instead of the web server. The increased loading speed is a result of the substantially faster response time that Varnish offers as compared to any web server software. Of course, this does not mean that the users will keep being served the very same content again and again, because any change on any of the web pages is reflected in the content that the Varnish platform keeps in its memory.

Varnish in Cloud Hosting

You can take advantage of Varnish’s potential and improve your websites’ loading speed regardless of the cloud hosting package that you’ve picked and you can enable and set up the platform with a couple of clicks of the mouse using the simple-to-use graphical interface offered by our next-gen Hepsia Control Panel. During the process, you will be able to choose two separate things – how many sites will employ Varnish, i.e. the number of instances, and how much info will be cached, i.e. the amount of memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can order more instances and less memory and vice versa. In case you have a lot of content on a particular website and you win a lot of site visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP address for the websites that will use Varnish. Hepsia will provide you with simple one-click controls for deactivating or rebooting any instance, for erasing the cache for each website and for seeing comprehensive system logs.
