Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It is a web application accelerator that can accelerate the loading speed of a website by up to 1000%, depending on the content itself. Every time 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. In this way, the web browser request from the visitor is not handled by the server and the web page will open considerably faster, as Varnish can deliver data many times faster than any web server software. The end result will be a substantially faster loading site, which means a greatly improved browsing experience. In case any of the cached webpages is updated on the live site, the content that Varnish stores in its system memory is ‘refreshed’ as well, so the users will not end up seeing outdated content.

Varnish in Shared Website Hosting

You can use Varnish’s full potential and boost your websites’ loading speed irrespective of the shared website hosting plan that you’ve selected and you can enable and configure the platform with a few mouse clicks using the simple-to-work-with interface offered by our leading-edge Hepsia Control Panel. In the meantime, you’ll be able to select two different things – how many websites will employ the Varnish platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances with less memory and the other way around. In case you’ve got plenty of content on a certain website and you draw numerous 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 the Varnish platform. The Hepsia Control Panel will offer you simple 1-click buttons for discontinuing or restarting any instance, for deleting the cache associated with any Internet site and for checking detailed system logs.

Varnish in Semi-dedicated Servers

Varnish is a feature, which comes as standard with all Linux semi-dedicated plans that we are offering and you can use it for load distribution purposes. It’s available in your Hepsia hosting Control Panel. The data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any site that you host in the account. In case you need more, you can increase the system memory allocation. The memory itself is offered in increments of 32 MB in the Upgrades section of the Control Panel. The very same section will permit you to enable more instances too, if you wish to use the Varnish platform with multiple Internet sites. The two upgrades can be added independently – you can cache the content of a single large-sized Internet site or run a number of websites with the default memory allocation. You can take full advantage of the Varnish platform if you have a dedicated IP address and you can get one with your semi-dedicated plan as well. Hepsia will grant you total control over the caching platform and, with no more than a click, you will be able to delete the cached content, to see a log or to restart an instance.

Varnish in VPS Servers

You can use Varnish with each of our VPS server packages at no extra charge, as the content caching platform is pre-installed and is included by default. The sole condition is that the Virtual Private Server must come with the Hepsia hosting Control Panel, via which you will be able to activate Varnish for any of your Internet sites with just a couple of clicks. Each plan includes a different amount of system memory for data caching purposes, but you’ll get no less than several hundred MB, which is sufficient enough even for several traffic-hungry Internet sites. Shortly after you activate Varnish, it’ll begin caching the content that your website visitors open, so you will notice the considerably better web page load speeds and the lowered load on your Virtual Private Server very soon. The Varnish platform will permit you to use a less costly virtual machine, since you will not need that much power to guarantee the correct operation of your websites even if you manage resource-consuming sites with numerous visitors. Optimal results are achieved if the websites that use Varnish use also a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish content caching platform at no extra cost and you will have complete control over it via a pretty simple-to-navigate graphical interface – you will be able to start, to stop or to restart an instance, to view an exhaustive system log, to clear the cached files for any website and much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you own resource-swallowing Internet sites with an enormous number of visitors, you will notice the significantly better site loading speeds and the reduced load on your dedicated machine. This will happen shortly after you begin using the Varnish platform, as it will need a certain amount of time to cache the web pages that people request. You can get the most out of the platform’s capability if the websites that are using it use also a dedicated IP address, but due to the fact that your server comes with a few IPs by default, you will not need to pay anything on top of the monthly fee for the server itself.
