Varnish is a web app accelerator platform, which caches information for faster access. It’s occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and a web browser. When a website visitor accesses a certain page, the content is requested by the browser, and then the web server handles this browser request and sends back the requested information. If Varnish is enabled for a given site, it will cache its pages at the first request and if the visitor accesses a cached page once again, the data will be delivered by the caching platform and not by the web server. The accelerated speed is a result of the substantially faster response speed that Varnish offers as compared with any server software. Of course, this does not mean that the visitors will keep being served the very same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Website Hosting

If you host your sites under a cloud website hosting account with our company, you will be able to activate Varnish with a few clicks through your hosting Control Panel. The platform is offered as an upgrade with all our web hosting plans and you can select the number of the websites that will use it and the maximum amount of system memory that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not tied directly to each other, so you can choose whether you want 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 Varnish in case the sites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/reboot/deactivate an instance, clear the cached data independently for each website that uses the Varnish platform or view a comprehensive system log.

Varnish in Semi-dedicated Hosting

All our semi-dedicated hosting come with Varnish by default, so you can take advantage of the web app accelerator tool and improve the speed of any site that you host on our semi-dedicated servers. You will get 64 MB of system memory particularly for the Varnish accelerator at no extra charge and you can create an instance with no more than a couple of clicks from 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 MB in the Control Panel’s Upgrades section and it will be available to you right away. You can also add more instances as a separate upgrade, so you can decide whether lots of content will be cached for a single site or if the memory will be utilized by several Internet sites. The Hepsia Control Panel will permit you to restart or to cancel any instance, to check the system log file associated with it or to delete the cached content using single-click controls. To get the most out of the Varnish accelerator, you can set a dedicated IP for the Internet sites that will employ it.

Varnish in VPS Web Hosting

You can use Varnish with all our virtual private server packages at no extra cost, since the caching platform is pre-installed and is included by default. The only condition is that the virtual server must be ordered with the Hepsia hosting Control Panel, via which you will be able to activate Varnish for any of your websites with only a couple of clicks of the mouse. Each VPS package includes a different amount of memory for content caching purposes, but you’ll get no less than several hundred megabytes, which is sufficient even for several traffic-intensive websites. Soon after you enable Varnish, it will begin caching the content that your website visitors open, so you will notice the significantly faster webpage load times and the less load on the VPS server in no time. Varnish will allow you to use a less expensive VPS, since you won’t require that many resources to sustain the uninterrupted operation of your sites even if you own large-sized Internet sites with many visitors. Optimal results are achieved if the Internet sites which use the Varnish platform use also a dedicated IP address.

Varnish in Dedicated Servers Hosting

In case you order a dedicated server with the Hepsia Control Panel, you’ll get the Varnish platform at no additional fee and you’ll have total control over it through an exceptionally intuitive graphical interface – you will be able to start, to stop or to reboot an instance, to view a detailed system log, to clear the cached files for any website and much, much more. Varnish will have several GB of system memory at its disposal, so even if you run large websites with a lot of visitors, you will notice the significantly better site loading times and the reduced load on your dedicated machine. This will become a fact shortly after you begin using the Varnish platform, since it will require a certain amount of time to cache the pages that people access. You can take full advantage of the platform’s potential in case the sites that are using it use also a dedicated IP address, but owing to the fact that your server comes with a couple of IPs by default, you will not need to pay anything on top of your monthly charge for the machine itself.
