Varnish is a web application accelerator platform, which caches data for faster access. It is occasionally called a caching HTTP reverse proxy as well and it works between a web server and its users. When a site visitor opens a given web page, the content is requested by the Internet browser, and then the web server processes this browser request and sends back the necessary content. If Varnish is enabled for a particular website, it will cache the pages at the very first request and if the visitor visits a cached page again, the information will be delivered by the caching platform and not by the web server. The increased load speed is an end result of the substantially faster response time that Varnish offers as compared to any server software. Of course, this does not mean that the users will keep seeing the same content over and over again, as any update on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Shared Hosting

Varnish comes as an optional upgrade with all our shared hosting. You can add it to your web hosting account through the Hepsia Control Panel, which is offered with all shared plans and you will get a rather simple-to-use interface, which will grant you full control over the data caching system. Using one-click quick-access buttons, you can restart or disable any of the instances, i.e. Varnish will no longer work for a specific website. You can also see a comprehensive log or clear the cache for any of the websites. When you add Varnish to your hosting package, you will be able to choose the total amount of system memory that will be available to you for content caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 MB and, for maximum performance, you can assign a dedicated IP address to the sites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have a lot of gratified visitors.

Varnish in Semi-dedicated Hosting

All our semi-dedicated packages include Varnish by default, so you can make full use of the web application accelerator tool and enhance the loading speed of any website that you host on our platform. You will get 64 MB of system memory particularly for Varnish at no additional charge and you will be able to activate an instance with no more than a couple of mouse clicks from the Hepsia Control Panel, which comes with the semi-dedicated server plans. In case you need more memory, the latter is available in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be available to you straight away. You can also add more instances as an upgrade, so you can decide if lots of data will be cached for a single site or if the memory will be utilized by several sites. The Hepsia Control Panel will allow you to reboot or to shut down any instance, to see the system log file associated with it or to clear the cached content using single-click controls. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the sites which will use it.

Varnish in VPS Hosting

We offer Varnish with all Hepsia-managed Linux VPS hosting packages, so in case you get a server with this Control Panel, you will be able to make use of the content caching platform at no extra fee. Varnish can utilize different amounts of memory for content caching purposes based on the very Virtual Private Server plan that you’ve picked during the registration process, but at any rate, this amount won’t be less than several hundred MB. This is quite enough to boost the overall performance of several different traffic-consuming Internet sites, so the faster site load speeds and the less load on the machine will be perceivable. The result may not be obvious momentarily, since Varnish will need some time to cache the content that visitors open, but shortly after you activate it, you’ll observe its full potential. This platform will permit you to use a less powerful Virtual Private Server and to pay less money to get the exact same performance you’d get with a higher-end machine without Varnish.

Varnish in Dedicated Web Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish platform at no extra charge and you will exert full control over it via an extremely easy-to-work-with interface – you will be able to start, to discontinue or to restart an instance, to browse a comprehensive system log, to clear the cached content associated with any site and much more. The Varnish caching platform will have several gigabytes of system memory at its disposal, so even if you run busy Internet sites with lots of visitors, you’ll notice the significantly better website loading speeds and the reduced load on your dedicated server. This will happen shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the web pages that people browse. You can get the most out of the platform’s capacity if the sites that are using it use also a dedicated IP address, but since your server comes with a few IP addresses by default, you will not need to pay anything on top of your monthly charge for the server itself.
