Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the speed of any Internet site, sometimes even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical server and to increase the browsing speed for the site visitors. Every time a visitor loads a page on a certain website, the browser request is taken care of by the web server and the requested data is returned as a response. If the Varnish accelerator is activated, it caches the pages that the visitor opens and in case any of them is opened again, it is delivered by Varnish and not by the server directly. The improvement in the overall performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is edited in the meantime, the cached pages will also be updated the next time somebody attempts to open them.

Varnish in Cloud Hosting

You can unleash Varnish’s potential and boost the load speed of your websites regardless of the cloud hosting package that you’ve selected and you can activate and set up the platform with several clicks from the simple-to-work-with graphical interface offered by our next-generation Hepsia Control Panel. During the procedure, you will be able to select two separate things – how many sites will use the Varnish platform, in other words – the number of instances, and how much content will be cached, i.e. 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 use more instances with less memory and the other way around. If you have a lot of content on a given Internet site and you receive lots of visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP for the Internet sites that will use Varnish. Hepsia will provide you with easy 1-click controls for stopping or restarting any instance, for clearing the cache associated with each Internet site and for seeing detailed system logs.

Varnish in Semi-dedicated Hosting

Varnish is a feature, which is included by default with all Linux semi-dedicated hosting offered by our company and you can use it for load balancing purposes. It is available in your Hepsia Control Panel. The caching platform comes with 64 MB of system memory for cached data storing purposes and you can use it with any website that you host in the semi-dedicated server account. In case you are in need of more, you can increase the system memory quota. The memory itself is offered in increments of 32 megabytes in the Upgrades section of the Control Panel. The exact same Upgrades section will allow you to create more instances as well, in case you wish to use the Varnish caching platform with multiple sites. The two upgrades can be ordered independently – you can cache the content of one single large-scale site or use several sites with the default memory allowance. You can take full advantage of the Varnish platform in case you have a dedicated IP and you can get one with your semi-dedicated plan as well. The Hepsia Control Panel will grant you complete control over the platform and, with no more than one click, you will be able to delete the cached content, to see a system log or to restart an instance.

Varnish in VPS Web Hosting

You can take full advantage of the workload balancing potential of Varnish with any of our Linux VPS web hosting when you choose Hepsia as your hosting Control Panel. The content caching platform is available by default and the system memory that it will be able to use to cache your website content depends upon the particular Virtual Private Server plan that you have selected, but even with the lower-end packages, you will have no less than several hundred megabytes of memory at your disposal solely for data caching purposes. This amount is sufficient to optimize the overall performance of numerous sites. It’ll take a little time for you to detect the effects, as Varnish caches the content that site visitors open, but soon after that you will notice the significantly lowered load on the VPS and the accelerated Internet site load speed. Varnish will permit you to use a lower-end VPS plan for Internet sites which would typically require a more expensive web hosting service.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia Control Panel, you’ll obtain Varnish at no extra fee and you will have total control over it via a pretty simple-to-navigate interface – you’ll be able to start, to cancel or to reboot an instance, to browse an elaborate system log, to clear the cached data associated with any site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you manage heavy sites with numerous visitors, you’ll notice the considerably faster site load speeds and the reduced server load. This will become a fact shortly after you start using the Varnish platform, since it will require some time to cache the web pages that users open. You can make the most of the platform’s capability if the websites that are using it also use a dedicated IP, but owing to the fact that your dedicated server comes with a few IP addresses by default, you won’t have to pay anything on top of the monthly charge for the machine itself.
