Varnish is a web application accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, sometimes even by 100 percent, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to accelerate the browsing speed for the site visitors. Every time a visitor opens a page on a given Internet site, the web browser request is processed by the web server and the requested content is delivered as a response. If Varnish is activated, it caches the web pages that the visitor browses and in case any of them is accessed once more, it’s delivered by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator processes the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the site visitors. In case any data is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody tries to access them.

Varnish in Website Hosting

You can use Varnish’s full potential and boost the loading speed of your websites irrespective of the website hosting plan that you’ve picked and you can activate and configure the data caching platform with a few clicks of the mouse using the simple-to-use interface offered by our leading-edge Hepsia Control Panel. During the process, you’ll be able to select two different things – how many Internet sites will use 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 is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances and less memory and the other way around. In case you’ve got plenty of content on a given site and you receive numerous website visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. The Hepsia Control Panel will offer you easy one-click buttons for shutting down or rebooting any instance, for deleting the cache for any website and for seeing in-depth system logs.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can use the web accelerator tool and increase the speed of any website that you host on our platform. You’ll get 64 megabytes of memory dedicated to the Varnish accelerator at no additional charge and you can enable an instance with no more than a few clicks through the Hepsia Control Panel, which comes with the semi-dedicated packages. In case you need more memory, the latter is available in increments of 32 MB through the Control Panel’s Upgrades section and it will be at your disposal momentarily. You can also add more instances as an upgrade, so you can decide if lots of content will be cached for a single website or if the available memory will be used by different websites. Hepsia will permit you to restart or to discontinue any instance, to view the system log file for it or to delete the cached files using one-click controls. To take full advantage of the Varnish accelerator, you can allocate a dedicated IP address to the sites that will use it.

Varnish in VPS

We provide Varnish with all of the Hepsia-managed Linux VPS, so if you order a server with this Control Panel, you’ll be able to make the most of the content caching platform at no extra charge. The Varnish platform can use different amounts of memory for content caching purposes depending on the specific VPS package that you’ve picked during the subscription process, but in any case, this amount will not be less than several hundred MB. This is more than enough to boost the work of several resource-consuming websites, so the better site browsing speeds and the less load on the machine will be perceptible. The result may not be visible instantly, as Varnish will need a certain amount of time to cache the content that visitors request, but shortly after you set it up, you’ll perceive its full potential. This caching platform will permit you to use a lower-end Virtual Private Server and to pay less money to get the exact same performance you would get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Hosting

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish data caching platform at no extra fee and you’ll exert full control over it via an exceptionally intuitive interface – you will be able to start, to disable or to restart an instance, to see an exhaustive log, to delete the cached content associated with any site and much, much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you host traffic-hungry websites with many visitors, you’ll notice the tremendously better web page load speeds and the lowered load on your dedicated machine. This will become a fact soon after you start using the Varnish platform, since it will require some time to cache the site content that visitors request. You can get the most out of the platform’s potential if the Internet sites that are using it also use a dedicated IP, but owing to the fact that your dedicated server includes several IP addresses by default, you will not have to pay anything on top of the monthly fee for the server itself.
