Varnish is a web accelerator platform, which caches content for quicker access. It’s occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor accesses a particular page, the content is requested by the web browser, and then the web server handles this browser request and sends back the needed information. If Varnish is activated for a particular site, it will cache the pages on the very first request and if the user visits a cached page once more, the data will be delivered by the caching platform and not by the server. The increased speed is an end result of the much faster response time that Varnish offers as compared with any server software. At the same time, this doesn’t mean that the visitors will continue being served the same content again and again, because any change on any of the web pages is reflected in the content that Varnish saves in its 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 via your Control Panel. The caching platform is offered as an optional upgrade with all our shared web hosting plans and you can choose how many sites will use it and the maximum amount of system memory that will be available for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not directly linked to each other, so you can choose if you need lots of memory for one single large-sized site or less memory for several smaller ones. You can make use of the full potential of the Varnish platform if the websites use a dedicated IP. With the Control Panel, you can easily start/reboot/cancel an instance, delete the cached contents individually for each site that employs the Varnish platform or see a detailed log file.

Varnish in Semi-dedicated Servers

The Varnish content caching platform is an essential part of the standard set of services that you will acquire in case you decide to host your sites in a semi-dedicated server account. You can set it up for any of your Internet sites through our advanced Hepsia hosting Control Panel. The default memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the websites that can use this caching platform simultaneously. As these two things are not linked to each other, you can use a few sites with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform performs best when you allocate a dedicated IP to the sites that utilize its power. The Hepsia Control Panel will give you an easy way of rebooting any instance. On top of that, you will be able to clear the cached files with only one single click of the mouse.

Varnish in Dedicated Servers

When you need a more powerful hosting solution and you get one of the dedicated web hosting plans offered by our company, you will be able to use the Varnish content caching platform to enhance the performance of your websites at no additional charge as long as the server is ordered with our leading-edge Hepsia Control Panel. Its easy-to-navigate GUI will enable you to monitor system processes, to delete the cached files or to reboot any instance with one single mouse click. The minimal amount of memory that the platform can employ to cache site content is 3 gigabytes, which is quite enough for a vast selection of resource-consuming sites, so your server will be able to deal with a substantial load while your visitors are having a smooth browsing experience. Since your server will come with several different dedicated IP addresses, you will be able to use Varnish’s full capacity.
