Varnish is a web application accelerator platform, which caches information for the sake of faster response times. It’s sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and a web browser. When a website visitor opens a particular page, its content is requested by the browser, and then the web server handles this browser request and delivers the necessary information. If Varnish is enabled for a certain website, it will cache the pages at the very first request and in case the visitor accesses a cached page for a second time, the data will be delivered by the accelerator platform and not by the server. The increased speed is a result of the significantly faster response speed that Varnish offers compared to any web server software. Of course, this does not mean that the users will continue being served the same content again and again, as any change on any of the pages is reflected in the content that Varnish caches in its memory.

Varnish in Web Hosting

You can unleash Varnish’s potential and speed up your websites irrespective of the web hosting plan that you’ve picked and you can enable and configure the platform with several clicks through the intuitive GUI offered by our advanced Hepsia hosting Control Panel. In the meantime, you’ll be able to select two separate things – how many sites will use the Varnish caching platform, i.e. the number of instances, and how much info will be cached, in other words – the amount of memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and vice versa. If you have lots of content on a particular website and you gain numerous site visitors, more memory will give you a better result. You may also consider employing a dedicated IP address for the websites that will use Varnish. Hepsia will offer you simple one-click buttons for turning off or rebooting any instance, for erasing the cache associated with any website and for viewing comprehensive system logs.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can use the web accelerator tool and increase the load speed of any website that you host on our semi-dedicated servers. You will get 64 MB of system memory particularly for the Varnish accelerator at no additional cost and you’ll be able to create an instance with no more than a few clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you need more memory, the latter is offered in increments of 32 MB through the Control Panel’s Upgrades section and it will be available to you instantaneously. You can also add more instances as a separate upgrade, so you can decide if lots of content will be cached for a single site or if the available memory will be utilized by several Internet sites. Hepsia will allow you to restart or to terminate any instance, to view the system log for it or to delete the cached files using single-click controls. To get the most out of Varnish, you can set a dedicated IP address for the Internet sites that will employ it.

Varnish in VPS Hosting

You can take full advantage of the load balancing capabilities of Varnish with all our Linux VPS hosting in case you select Hepsia as your Control Panel. The Varnish data caching platform is offered by default and the amount of system memory that it’ll be able to utilize to cache your website content depends upon the given Virtual Private Server package that you’ve selected, but even with the lower-end plans, you will have at least several hundred megabytes of system memory at your disposal only for data caching purposes. This amount is sufficient enough to optimize the overall performance of numerous Internet sites. It’ll take some time for you to observe the results, as the Varnish platform caches the content that visitors browse, but after that you’ll notice the considerably lowered load on your Virtual Private Server and the accelerated site loading speed. The Varnish caching platform will allow you to make use of a lower-end VPS plan for websites that would usually require a more pricey web hosting service.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish caching platform at no additional fee and you’ll have total control over it via an amazingly intuitive graphical interface – you will be able to start, to disable or to restart an instance, to browse an in-depth log, to delete the cached content associated with any Internet site and much, much more. Varnish will have several gigabytes of system memory at its disposal, so even if you run resource-hungry websites with numerous visitors, you will notice the substantially better site load times and the reduced load on your server. This will happen soon after you start using the Varnish platform, since it will require some time to cache the content that visitors browse. You can get the most out of the platform’s potential in case the websites that are using it use also a dedicated IP address, but since your server comes with a few IPs by default, you won’t have to pay anything on top of the monthly fee for the server itself.
