Varnish is a website accelerator, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any website, sometimes even by 100 percent, depending on the content itself. This tool is sometimes referred to as an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to increase the access speed for the site visitors. Anytime a visitor accesses a page on a particular website, the web browser request is taken care of by the web server and the requested data is sent as a response. If the Varnish accelerator is enabled, it caches the web pages that the site visitor browses and if any of them is loaded once more, it’s served by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the users. In case any content is updated meanwhile, the cached pages will also be updated the next time somebody attempts to access them.

Varnish in Shared Website Hosting

You can take advantage of Varnish’s full potential and increase your sites’ loading speed irrespective of the shared website hosting plan that you’ve chosen and you can enable and configure the data caching platform with several clicks using the user-friendly interface offered by our next-gen Hepsia Control Panel. In the meantime, you will be able to choose two separate things – how many Internet sites will employ the Varnish caching 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 MB and is not bound to the number of instances, so you can add more instances and less memory and the other way around. In case you have lots of content on a given website and you receive numerous visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the sites that will use the Varnish caching platform. Hepsia will provide you with easy one-click buttons for cancelling or rebooting any instance, for deleting the cache for each site and for checking in-depth system logs.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is included in the default service set that you’ll acquire if you choose to host your sites in a semi-dedicated server account. You can enable it for any of your Internet sites through our next-gen Hepsia hosting Control Panel. The default amount of system memory that Varnish can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this caching platform at the same time. Since these two things are not tied to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single site. The Varnish caching platform works best if you get a dedicated IP address for the websites that utilize its power. The Hepsia Control Panel will offer you a simple way of restarting any instance. On top of that, you’ll be able to delete the cached data with only one click.

Varnish in VPS Servers

We offer Varnish with all of the Hepsia-managed VPS plans, so if you obtain a VPS with this hosting Control Panel, you will be able to take advantage of the data caching platform at no extra cost. The Varnish platform can utilize different amounts of system memory for data caching purposes based on the specific Virtual Private Server plan that you’ve picked during the VPS order process, but in any case, this amount will not be less than several hundred megabytes. This is more than enough to optimize the work of several resource-requiring websites, so the faster web page browsing speeds and the lowered server load will be noticeable. The effect may not be apparent momentarily, since the Varnish platform will require a certain amount of time to cache the website content that visitors open, but soon after you enable it, you will perceive its full potential. This caching platform will allow you to use a less powerful VPS server and to pay less money to get the same performance you’d get with a higher-end machine without Varnish.

Varnish in Dedicated Servers

All dedicated web hosting plans that are ordered with the in-house built Hepsia website hosting Control Panel include Varnish, which is among the pre-installed platforms that you will get with the dedicated machine. The Varnish caching platform can be configured and managed without efforts through Hepsia’s easy-to-navigate GUI and, with no more than one single click of the mouse, you can view an elaborate log, add or reboot an instance, clear the cache for any site and much, much more. Shortly after you enable Varnish for a particular domain or subdomain, it will start caching the webpages browsed by the website visitors and as soon as it has cached enough content, you’ll perceive a considerably better website performance plus a decreased load on the dedicated machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the platform for load distribution purposes even if you run a large number of Internet sites on your dedicated machine.
