Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, as it can increase the speed of any Internet site, at times even by 100%, depending on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to lower the overall server load and to accelerate the access speed for the website visitors. Anytime a visitor loads a page on a certain website, the browser request is handled by the web server and the requested data is returned as a response. If Varnish is activated, it caches the pages that the visitor browses and if any of them is accessed for a second time, it is served by Varnish and not by the web server directly. The improvement in the performance comes from the fact that the accelerator processes the web requests substantially faster than any web server, which leads to much faster browsing speeds for the site visitors. If any content is modified in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Cloud Web Hosting

You can unlock Varnish’s potential and accelerate the loading speed of your sites irrespective of the cloud web hosting package that you’ve selected and you can add and configure the platform with a few clicks from the simple-to-use GUI offered by our next-generation Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two different things – how many sites will employ the Varnish platform, i.e. the number of instances, and how much information will be cached, in other words – the amount of memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can add more instances and less memory and vice versa. In case you have plenty of content on a particular Internet site and you draw numerous site visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP for the websites that will use Varnish. The Hepsia Control Panel will provide you with easy one-click controls for turning off or restarting any instance, for clearing the cache for each Internet site and for checking comprehensive logs.

Varnish in Semi-dedicated Hosting

Varnish is included by default with all Linux semi-dedicated hosting that we offer and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any website that you host in your semi-dedicated account. If you need more than that, you can increase the system memory quota. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same Upgrades section will allow you to enable more instances too, in case you would like to use Varnish with more websites. The two things can be added separately – you can cache the content of one single resource-consuming website or run several sites with the default memory allocation. You can take full advantage of Varnish in case you’ve got a dedicated IP address and you can get one with your semi-dedicated package as well. The Hepsia Control Panel will grant you total control over the caching platform and, with no more than one single click of the mouse, you’ll be able to delete the cached data, to see a log or to restart an instance.

Varnish in Dedicated Web Hosting

If you want a powerful hosting solution and you acquire any of the Linux dedicated web hosting that we offer, you can use the Varnish platform to improve the overall performance of your Internet sites at no extra charge on the condition that the dedicated machine is ordered with our advanced Hepsia Control Panel. Its simple-to-use interface will permit you to keep track of system processes, to delete the cached content or to restart any instance with one mouse click. The smallest amount of memory that Varnish can employ to cache site content is 3 GB, which is quite enough for an enormous number of resource-intensive sites, so your dedicated server will be able to handle a huge load while your site visitors are enjoying a seamless browsing experience. Since your server will come with several different dedicated IP addresses, you’ll be able to use Varnish’s full capacity.
