Varnish is a web app accelerator platform, which caches info for the sake of faster response times. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a website visitor opens a certain webpage, its content is requested by the Internet browser, and then the server handles this browser request and delivers the requested data. If Varnish is activated for a certain site, it will cache the pages at the very first visit and in case the user opens a cached page again, the content will be delivered by the caching platform instead of the server. The improved loading speed is an end result of the significantly faster response time that the Varnish platform offers as compared to any server software. At the same time, this does not mean that the visitors will continue being served the exact same content over and over again, since any modification on any of the web pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Hosting

Varnish comes as an optional upgrade with all our cloud hosting plans. You can add it to your account through the Hepsia hosting Control Panel, which is available with all shared plans and you’ll get a rather simple-to-use GUI, which will grant you full control over the data caching system. Using 1-click quick-access buttons, you can restart or turn off any of the instances, in other words – Varnish will no longer be activated for a specific site. You can also see a detailed system log file or erase the cache for any of the Internet sites. When you add Varnish to your hosting package, you’ll be able to select the maximum amount of memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can get a dedicated IP for the sites that will use Varnish. This will permit you to get the most out of your sites and to have lots of gratified site visitors.

Varnish in Semi-dedicated Servers

All our Linux semi-dedicated servers come with Varnish by default, so you can use the website accelerator tool and increase the loading speed of any site that you host on our semi-dedicated servers. You will get 64 megabytes of system memory particularly for the Varnish accelerator at no additional cost and you can create an instance with no more than a few mouse clicks through the Hepsia hosting Control Panel, which is included with the semi-dedicated server packages. In case you need more memory, the latter is available in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be at your disposal momentarily. You can also add more instances as a separate upgrade, so you can choose if lots of content will be cached for one site or if the available memory will be utilized by multiple websites. The Hepsia Control Panel will enable you to reboot or to remove any instance, to view the system log associated with it or to delete the cached data using one-click controls. To take full advantage of Varnish, you can assign a dedicated IP address to the Internet sites that will use it.

Varnish in VPS Servers

You can use Varnish with each of our VPS server packages at no extra charge, as the platform is pre-installed and is included by default. The only condition is that the Virtual Private Server must be ordered with the Hepsia hosting Control Panel, via which you’ll be able to set up Varnish for any of your websites with only a couple of mouse clicks. Each package features a different amount of memory for data caching purposes, but you will have no less than several hundred MB, which is sufficient enough even for multiple resource-hungry websites. Soon after you enable the Varnish platform, it will start caching the content that your visitors access, so you will notice the considerably better webpage loading times and the decreased load on your virtual server in no time. The platform will permit you to use a less pricey Virtual Private Server, as you won’t require that many resources to guarantee the correct operation of your sites even if you run heavy-traffic Internet sites with a lot of visitors. Best results are achieved if the websites that use the Varnish platform also use a dedicated IP address.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish content caching platform at no additional charge and you will have complete control over it via an exceptionally simple-to-work-with graphical interface – you will be able to start, to discontinue or to restart an instance, to browse a detailed system log, to clear the cached content for any site and much, much more. The Varnish platform will have several GB of virtual memory at its disposal, so even if you run resource-absorbing Internet sites with lots of visitors, you’ll notice the significantly faster web page load speeds and the reduced load on the machine. This will happen shortly after you begin using Varnish, as it will require a certain amount of time to cache the content that users browse. You can get the most out of the platform’s capacity if the sites that are using it also use a dedicated IP address, but since your dedicated server comes with several IP addresses by default, you will not need to pay anything on top of your monthly fee for the machine itself.
