Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It is a web app accelerator that can boost the load speed of a site by up to 1000%, based on its content. Each time a visitor opens any page on a website 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 server and the web page will load much faster, as Varnish can deliver data many times faster than any web server software. The end result will be a considerably faster loading website, which leads to an enormously improved website browsing experience. When any of the cached web pages is updated on the live website, the content that Varnish keeps in its memory is ‘refreshed’ as well, so the website visitors will not end up seeing outdated content.

Varnish in Shared Hosting

If you host your websites under a shared hosting account with us, you will be able to add Varnish with a few mouse clicks via your Control Panel. The content caching platform is offered as an optional upgrade with all our shared plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can choose whether you want plenty of memory for one single large website or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the websites use a dedicated IP address. Using the hosting Control Panel, you can easily start/reboot/stop an instance, clear the cached files individually for each site that employs the Varnish platform or check a detailed system log.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can use the web application accelerator tool and improve the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 MB of memory particularly for the Varnish accelerator at no additional charge and you can enable an instance with no more than a few mouse clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. If you need more memory, the latter is available in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be at your disposal immediately. You can also order more instances as an upgrade, so you can choose if a lot of content will be cached for a single site or if the available memory will be utilized by several sites. The Hepsia Control Panel will enable you to restart or to delete any instance, to check the system log file for it or to delete the cached content using single-click controls. To take full advantage of the Varnish accelerator, you can assign a dedicated IP address to the websites which will employ it.

Varnish in VPS Hosting

You can take full advantage of the workload balancing potential of Varnish with each of our VPS hosting packages in case you choose Hepsia as your web hosting Control Panel. The content caching platform is available by default and the amount of system memory that it’ll be able to utilize to cache the content of your websites is dependent upon the specific Virtual Private Server package that you’ve chosen, but even with the lower-end plans, you will have at least several hundred megabytes of memory at your disposal exclusively for caching purposes. This amount is sufficient enough to optimize the performance of numerous sites. It’ll take a little time for you to observe the results, since the Varnish platform caches the content that site visitors access, but soon after that you will notice the considerably less load on your virtual machine and the improved website load speed. Varnish will permit you to use a less powerful Virtual Private Server package for sites which would normally require a more expensive web hosting service.

Varnish in Dedicated Web Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish data caching platform at no extra cost and you’ll have total control over it through a very easy-to-use GUI – you’ll be able to start, to deactivate or to restart an instance, to see an elaborate system log, to delete the cached content for any Internet site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you’ve got traffic-hungry sites with numerous visitors, you will notice the tremendously faster web page load times and the lowered load on the machine. This will become a fact soon after you begin using Varnish, since it will need a certain amount of time to cache the website content that people access. You can take full advantage of the platform’s capacity in case the websites that are using it also use a dedicated IP address, but due to the fact that your dedicated server comes with several IP addresses by default, you will not need to pay anything on top of your monthly charge for the server itself.
