Varnish is a web accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, sometimes even by 100%, based on the content. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall load on the physical server and to accelerate the access speed for the website visitors. Each time a visitor loads a page on a certain site, the browser request is handled by the web server and the requested content is delivered as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and if any of them is accessed once more, it is fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the website visitors. In case any data is changed meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody tries to access them.

In case you host your websites under a cloud web hosting account with us, you will be able to activate Varnish with a couple of clicks of the mouse from your Control Panel. The caching platform is available as an upgrade with all our packages and you can select how many sites will use it and the maximum amount of system memory that will be available 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’re not directly linked to each other, so you can choose if you want lots of memory for one single large-sized site or less memory for multiple smaller ones. You can make use of the full potential of the Varnish platform in case the sites use a dedicated IP address. With the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, delete the cached files individually for each website which employs the Varnish platform or view an exhaustive log.
