Varnish is a web accelerator platform, which caches information for the sake of quicker access. It is occasionally referred to as a caching HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a website visitor accesses a certain webpage, its content is requested by the web browser, and then the web server processes this browser request and delivers the needed data. If Varnish is enabled for a site, it will cache its pages on the very first visit and in case the visitor visits a cached page again, the information will be delivered by the caching platform and not by the web server. The increased loading speed is a result of the significantly faster response time that the Varnish platform offers as compared with any web server software. Of course, this does not mean that the website visitors will keep being served the very same content over and over again, since any change on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.

Varnish in Web Hosting

In case you host your sites in a web hosting account with us, you will be able to activate Varnish with a few clicks via your Control Panel. The content caching platform comes as an optional upgrade with all our shared web hosting plans and you can select the number of the websites that will use it and the total amount of system memory that will be available for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the number of instances and the amount of memory and they are not tied directly to each other, so you can choose if you need plenty of memory for one single large-sized site or less memory for several smaller ones. You can take advantage of the full potential of the Varnish platform if the websites use a dedicated IP address. With the Control Panel, you can swiftly start/restart/disable an instance, delete the cached files individually for each site that employs the Varnish platform or see a comprehensive log file.

Varnish in Semi-dedicated Servers

Varnish is a feature, which comes by default with all Linux semi-dedicated servers that we are offering and you can use it for workload distribution purposes. It is available in your Hepsia Control Panel. The Varnish caching platform comes with 64 megabytes of system memory for cached data storing purposes and you can use it with any Internet site that you host in the account. In case you need more than that, you can increase the memory allowance. The memory itself is offered in increments of 32 MB in the Control Panel’s Upgrades section. The exact same Upgrades section will enable you to enable more instances too, in case you would like to use the Varnish platform with multiple sites. The two things can be ordered separately – you can cache the content of one single resource-intensive website or use several websites with the default memory allowance. You can take full advantage of Varnish if you have a dedicated IP and you can order one with your semi-dedicated plan as well. The Hepsia Control Panel will give you full control over the caching platform and, with no more than one single click, you’ll be able to clear the cached files, to view a system log file or to restart an instance.

Varnish in VPS Servers

You can use Varnish with any of our VPS server plans at no additional cost, since the caching platform is pre-installed and is offered by default. The one and only requirement is that the VPS server must be ordered with the Hepsia Control Panel, through which you will be able to set up Varnish for any of your sites with only a few mouse clicks. Each package comes with a different amount of system memory for data caching purposes, but you will get no less than several hundred MB, which is sufficient enough even for multiple resource-heavy sites. Soon after you activate the Varnish platform, it will begin caching the content that your site visitors open, so you’ll notice the significantly faster site load speeds and the reduced load on the Virtual Private Server very soon. The caching platform will permit you to use a less costly virtual server, since you won’t need that much power to sustain the correct operation of your websites even if you run heavy-traffic sites with plenty of visitors. Optimum results are accomplished if the sites which use the Varnish caching platform also use a dedicated IP.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the tailor-made Hepsia web hosting Control Panel come with Varnish, which is one of the pre-installed software platforms that you will get with the dedicated machine. The Varnish content caching platform can be set up and administered with ease via Hepsia’s simple-to-use graphical interface and, with no more than one click of the mouse, you can check a comprehensive system log, create or restart an instance, clear the cached files associated with any website and much more. Soon after you configure the Varnish platform for a certain domain or subdomain, it will begin caching the pages accessed by your site visitors and as soon as it has cached enough web content, you’ll witness a substantially faster website performance in addition to a decreased server load. With Varnish-dedicated virtual memory starting at 3 gigabytes, you will be able to use the software platform for workload balancing purposes even if you run a lot of sites on your machine.
