Varnish is a web application accelerator platform, which caches content for the sake of faster access. It’s sometimes referred to as an HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a site visitor loads a given webpage, the content is requested by the Internet browser, and then the web server processes this browser request and sends back the requested info. If Varnish is enabled for a certain website, it will cache its pages on the first request and in case the visitor opens a cached page once again, the info will be delivered by the caching platform and not by the web server. The improved speed is a result of the considerably faster response time that Varnish offers as compared to any server software. At the same time, this doesn’t mean that the site visitors will keep seeing the same content again and again, because any update on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Cloud Hosting

Varnish is offered as an optional upgrade with all our cloud hosting. You can add it to your account via the Hepsia Control Panel, which is available with all shared web hosting packages and you will get a quite easy-to-use interface, which will give you complete control over the caching platform. Using one-click quick-access controls, you can restart or cancel any of the instances, in other words – Varnish will no longer be enabled for a certain Internet site. You can also view an in-depth log file or delete the cache associated with any of the websites. When you add Varnish to your hosting package, you will be able to select the maximum amount of memory that will be available to you for data caching purposes and the number of the websites that will use Varnish. You can always get more memory in increments of 32 MB and, for best performance, you can get a dedicated IP for the websites that will use Varnish. This will enable you to get the most out of your websites and to have lots of gratified visitors.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the basic set of services that you will obtain in case you decide to host your Internet sites under a semi-dedicated server account. You can configure it for any of your sites through our innovative Hepsia Control Panel. The default system memory that the Varnish platform can use to cache data is 64 MB, but in case you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this platform at the same time. Since these two features aren’t bound to each other, you can use several websites with the default amount of memory or you can add more memory in increments of 32 MB and use all of it for a single web site. Varnish performs best if you use a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple means 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

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish data caching platform at no extra fee and you will have total control over it through a quite intuitive graphical interface – you’ll be able to start, to deactivate or to restart an instance, to view an exhaustive system log, to delete the cached data associated with any Internet site and much, much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you host resource-heavy websites with a huge number of visitors, you’ll notice the much better page load times and the decreased load on your dedicated machine. This will happen soon after you start using Varnish, as it will require a certain amount of time to cache the web pages that users browse. You can take full advantage of the platform’s capabilities in case the Internet sites that are using it also use a dedicated IP address, but since your dedicated server includes a few IP addresses by default, you will not need to pay anything on top of the monthly fee for the server itself.
