Varnish is a web application accelerator platform, which caches content for the sake of faster response times. It’s occasionally referred to as an HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor loads a given web page, its content is requested by the browser, and then the web server processes this request and sends back the requested content. If Varnish is activated for a website, it will cache its pages on the first request and if the visitor accesses a cached page once more, the info will be delivered by the caching platform instead of the web server. The accelerated load speed is an end result of the considerably faster response time that the Varnish platform offers compared to any server software. Of course, this doesn’t mean that the users will continue being served the very same content over and over again, because any change on any of the pages is reflected in the content that Varnish saves in its memory.

Varnish in Shared Hosting

You can unlock Varnish’s potential and accelerate the loading speed of your websites irrespective of the shared hosting plan that you’ve chosen and you can enable and set up the data caching platform with several clicks of the mouse via the simple-to-use graphical interface offered by our advanced Hepsia Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will use the Varnish platform, i.e. the number of instances, and how much data 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 and less memory and the other way around. If you’ve got a lot of content on a given site and you win lots of website visitors, more memory will guarantee you better results. You may also consider employing a dedicated IP for the websites that will use Varnish. The Hepsia Control Panel will offer you simple 1-click controls for shutting down or restarting any instance, for erasing the cache associated with any site and for seeing detailed system logs.

Varnish in Semi-dedicated Servers

All our semi-dedicated hosting plans include Varnish by default, so you can take full advantage of the web accelerator tool and enhance the loading speed of any site that you host on our semi-dedicated servers. You will get 64 MB of memory dedicated to the Varnish accelerator at no additional cost and you can activate an instance with no more than a few mouse clicks from the Hepsia Control Panel, which is included with the semi-dedicated server packages. In case you need more memory, the latter is offered in increments of 32 MB in the Control Panel’s Upgrades section and it will be at your disposal momentarily. You can also order more instances as an upgrade, so you can decide if a lot of data will be cached for a single site or whether the available memory will be utilized by several websites. Hepsia will permit you to restart or to stop any instance, to check the system log file for it or to clear the cached files using single-click controls. To take full advantage of Varnish, you can set a dedicated IP for the Internet sites which will use it.

Varnish in VPS Servers

We provide Varnish with all Hepsia-equipped VPS hosting plans, so if you purchase a server with this hosting Control Panel, you will be able to make the most of the content caching platform at no extra cost. The Varnish platform can use different amounts of memory for data caching purposes depending on the particular VPS plan that you’ve picked on the order form, but nevertheless, this amount will not be less than several hundred megabytes. This is more than enough to optimize the performance of a handful of resource-requiring Internet sites, so the faster page loading speeds and the lowered load will be discernible. The effect may not be distinguishable straight away, as the Varnish platform will require a certain amount of time to cache the content that users request, but soon after you enable it, you’ll perceive its full potential. This caching platform will allow you to use a less powerful server and to give less money to get the same performance you’d get with a higher-end virtual machine without Varnish.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish data caching platform at no extra fee and you will have complete control over it through a pretty easy-to-navigate interface – you’ll be able to start, to discontinue or to reboot an instance, to check a comprehensive system log, to clear the cached content associated with any Internet site and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you host high-demand sites with an enormous number of visitors, you will notice the tremendously better page load speeds and the less load on the machine. This will happen soon after you begin using Varnish, since it will need some time to cache the pages that users open. You can make the most of the platform’s capacity in case the websites that are using it also use a dedicated IP, but due to the fact that your server includes a couple of IPs by default, you won’t need to pay anything on top of your monthly fee for the machine itself.
