Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, sometimes even by 100 percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the browsing speed for the site visitors. Each time a visitor loads a page on a certain site, the browser request is handled by the web server and the requested data is served as a reply. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and in case any of them is opened once again, it is served by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator processes the browser requests significantly quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Cloud Hosting

You can use Varnish’s full potential and accelerate your websites regardless of the cloud hosting plan that you have selected and you can enable and set up the content caching platform with a few mouse clicks via the easy-to-use GUI offered by our innovative Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances with less memory and vice versa. In case you have lots of content on a given website and you attract a lot of visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the websites that will use the Varnish platform. The Hepsia Control Panel will provide you with simple 1-click buttons for shutting down or rebooting any instance, for erasing the cache for any website and for seeing detailed logs.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire Varnish at no extra charge and you’ll have full control over it through a rather simple-to-navigate interface – you will be able to start, to deactivate or to restart an instance, to browse an elaborate system log, to clear the cached files for any Internet site and much, much more. The Varnish platform will have several gigabytes of virtual memory at its disposal, so even if you host large-scale websites with numerous visitors, you will notice the substantially faster site load times and the reduced load on your dedicated server. This will happen shortly after you begin using the Varnish platform, since it will require some time to cache the website content that users access. You can get the most out of the platform’s capability in case the websites that are using it use also a dedicated IP address, but since your server comes with a couple of IP addresses by default, you won’t have to pay anything on top of your monthly fee for the machine itself.
