Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, sometimes even by 100 percent, based on the content. This tool is sometimes called an HTTP reverse proxy too and is used to lower the overall server load and to boost the access speed for the site visitors. Every time a visitor opens a page on a given site, the web browser request is taken care of 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 website visitor browses and in case any of them is loaded once again, it’s delivered by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator handles the browser requests considerably quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is changed meanwhile, the cached web pages will also be updated the next time somebody attempts to open them.

Varnish in Shared Website Hosting

If you host your websites in a shared website hosting account with us, you’ll be able to add Varnish with several clicks of the mouse from your hosting Control Panel. The caching platform comes as an optional upgrade with all our shared web hosting packages and you can choose the number of the websites that will use it and the maximum amount of system memory that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they’re not directly tied to each other, so you can decide whether you need plenty of memory for one single large-size site or less memory for multiple smaller ones. You can unlock the full potential of Varnish in case the websites use a dedicated IP. Using the Control Panel, you can easily start/restart/discontinue an instance, clear the cached contents individually for each website which employs Varnish or view a detailed system log file.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is included in the default service set that you will obtain in case you decide to host your websites under a semi-dedicated server account. You can set it up for any of your websites via our advanced Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this platform at the same time. As these two things are not tied to each other, you can use several sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single site. Varnish works best if you get a dedicated IP address for the sites that utilize its power. The Hepsia Control Panel will give you an easy way of rebooting any instance. On top of that, you will be able to delete the cached content with just a click.

Varnish in VPS Servers

You can take advantage of Varnish with any of our VPS server plans at no additional fee, as the content caching platform is pre-installed and is offered by default. The sole requirement is that the VPS must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to set up Varnish for any of your sites with just a couple of clicks of the mouse. Each VPS package includes a different amount of system memory for caching purposes, but you will get no less than several hundred megabytes, which is quite enough even for several large-sized sites. Shortly after you enable Varnish, it’ll begin caching the content that your site visitors request, so you will notice the substantially faster site loading times and the reduced load on your VPS server very soon. The Varnish platform will allow you to use a less costly virtual machine, since you will not need that many resources to sustain the proper operation of your websites even if you run traffic-consuming sites with a lot of visitors. Maximum results are accomplished if the websites which use the Varnish caching platform also use a dedicated IP address.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia hosting Control Panel, you will acquire the Varnish platform at no additional fee and you’ll exert total control over it via an extremely simple-to-use interface – you’ll be able to start, to cancel or to reboot an instance, to view an elaborate log, to clear the cache associated with any website and much more. Varnish will have several gigabytes of memory at its disposal, so even if you host large-size Internet sites with a large number of visitors, you’ll notice the significantly better web page load speeds and the reduced server load. This will happen soon after you begin using Varnish, as it will need a certain amount of time to cache the web pages that users browse. You can make the most of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but considering the fact that your server comes with a couple of IPs by default, you will not need to pay anything on top of your monthly charge for the server itself.
