Varnish is a web accelerator platform, which caches information for quicker access. It’s sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and a browser. When a visitor opens a particular web page, its content is requested by the web browser, and then the web server processes this request and sends back the requested content. If Varnish is activated for a particular site, it will cache the pages at the very first visit and if the visitor opens a cached page once more, the content will be delivered by the caching platform instead of the web server. The improved load speed is a result of the significantly faster response speed that the Varnish platform offers compared with any server software. Of course, this does not mean that the site visitors will continue seeing the exact same content over and over again, because any change on any of the pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Hosting

If you host your sites in a cloud hosting account with us, you will be able to add Varnish with a couple of clicks of the mouse through your hosting Control Panel. The caching platform is available as an optional upgrade with all our shared plans and you can choose how many websites will use it and the maximum amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they aren’t directly tied to each other, so you can decide whether you want a lot of memory for one single large-scale site or less memory for multiple smaller ones. You can unlock the full potential of the Varnish caching platform in case the websites use a dedicated IP address. Using the Control Panel, you can quickly start/reboot/stop an instance, clear the cached data individually for each site which employs the Varnish platform or check a detailed system log file.

Varnish in Semi-dedicated Servers

All our semi-dedicated service include Varnish by default, so you can make use of the web application accelerator and speed up any website that you host on our platform. You’ll get 64 megabytes of system memory exclusively for Varnish at no additional cost and you will be able to create an instance with no more than a couple of clicks via the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. In case you need more memory, the latter is available in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be available to you instantaneously. You can also order more instances as an upgrade, so you can choose whether lots of data will be cached for a single site or whether the available memory will be used by different Internet sites. The Hepsia Control Panel will enable you to reboot or to remove any instance, to check the system log file for it or to clear the cached data using 1-click controls. To get the most out of the Varnish accelerator, you can allocate a dedicated IP to the Internet sites which will employ it.

Varnish in VPS Servers

You can use Varnish with all our VPS server plans at no extra cost, since the data caching platform is pre-installed and is included by default. The one and only precondition is that the virtual machine must be ordered with the Hepsia hosting Control Panel, through which you will be able to set up Varnish for any of your websites with only a couple of clicks of the mouse. Each Virtual Private Server package features a different amount of system memory for caching purposes, but you’ll get at least several hundred MB, which is sufficient even for multiple traffic-hungry Internet sites. Shortly after you activate the Varnish platform, it’ll start caching the content that your visitors browse, so you’ll notice the tremendously better site load speeds and the less load on the VPS very soon. The caching platform will allow you to use a less pricey virtual machine, as you won’t need that many resources to guarantee the proper operation of your Internet sites even if you have resource-heavy sites with multiple visitors. Maximum results are achieved if the Internet sites that use the Varnish platform also use a dedicated IP.

Varnish in Dedicated Servers

You can employ Varnish to increase the speed of any site that is hosted on a dedicated server with us if the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the data caching platform ready to be used at no additional cost, but you’ll also have full control over it through the Hepsia Control Panel’s easy-to-work-with GUI. It will take only a click to start or stop an instance or to delete the cache associated with any Internet site that is using the Varnish platform and if you’re more knowledgeable, you can also check the platform’s logs. Varnish comes with no less than three gigabytes of virtual memory for caching purposes, so even in case you host lots of sites on your machine and they all use the Varnish caching platform, the difference in their performance will be perceivable. You’ll just need to wait for a little while till Varnish caches whatever pages the website visitors load on their end. The Varnish platform works best when the websites use a dedicated IP, but since our dedicated servers come with three free-of-charge IP addresses, you will have all that you need.
