Varnish is a data caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It is a web application accelerator tool that can accelerate the loading speed of a site by up to one thousand percent, depending on the content itself. Whenever a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not processed by the web server and the page will open substantially faster, since the Varnish platform can deliver data many times faster than any web server software. The end result will be a considerably faster loading page, which leads to a greatly improved website browsing experience. If any of the cached pages is updated on the actual website, the information that Varnish keeps in its system memory is ‘refreshed’ too, so the visitors will not see out-of-date data.

Varnish in Hosting

You can take advantage of Varnish’s full potential and accelerate the load speed of your websites regardless of the hosting package that you’ve selected and you can enable and set up the platform with several clicks using the easy-to-use GUI offered by our next-gen Hepsia hosting Control Panel. During the procedure, you’ll be able to select two different things – how many Internet sites will employ the Varnish platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is offered 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. If you have plenty of content on a certain site and you receive many site visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use Varnish. Hepsia will provide you with easy one-click buttons for removing or restarting any instance, for erasing the cache associated with any site and for viewing comprehensive system logs.

Varnish in Semi-dedicated Servers

The semi-dedicated service offered by us will allow you to use Varnish once your brand new semi-dedicated account has been set up, as the content caching platform is available by default. 64 megabytes of system memory will be allocated to Varnish the moment your account is activated, so you can take advantage of this load balancing software once your website has been published online. In case you’re in need of more system memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server momentarily. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not directly linked to the amount of memory that you use, which goes to say that you will have more freedom. The Varnish caching platform will seriously lower the load on the machine caused by your sites, so your website visitors can enjoy fast-opening pages. You will be able to manage the Varnish platform without effort through the Control Panel using quick-access controls. You’ll be able to start/cancel any of the instances that you’ve got, to clear the cached files associated with any of your sites or to check system logs.

Varnish in Dedicated Servers

If you need a more powerful hosting solution and you get one of the Linux dedicated service that we offer, you will be able to use the Varnish platform to boost the overall performance of your sites at no extra fee on the condition that the dedicated machine is ordered with our next-gen Hepsia Control Panel. Its simple-to-work-with interface will permit you to keep track of system processes, to delete the cached files or to restart any instance with one single click. The minimal amount of memory that the Varnish platform can use to cache site content is 3 gigabytes, which is quite enough for a vast collection of resource-hungry sites, so your dedicated server will be able to cope with a colossal load while your site visitors are having a smooth web browsing experience. Since your machine will include several dedicated IPs, you’ll be able to make use of Varnish’s maximum capacity.
