Varnish is a web app accelerator platform, which caches data for quicker access. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and a browser. When a site visitor opens a particular web page, the content is requested by the web browser, and then the server processes this request and returns the necessary data. If Varnish is enabled for a certain website, it will cache the pages on the first visit and in case the visitor visits a cached page once more, the data will be delivered by the accelerator platform and not by the web server. The increased loading speed is an end result of the substantially faster response speed that the Varnish platform offers compared with any server software. Of course, this does not mean that the visitors will continue seeing the very same content again and again, as any modification on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Web Hosting

In case you host your websites in a web hosting account with our company, you will be able to add Varnish with several clicks through your Control Panel. The data caching platform comes as an upgrade with all our web hosting packages and you can choose the number of the websites that will use it and the total storage space that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they are not tied directly to each other, so you can choose if you want lots of memory for one large-sized website or less memory for several smaller ones. You can make use of the full potential of Varnish in case the websites use a dedicated IP address. With the Control Panel, you can quickly start/restart/remove an instance, clear the cached data independently for each website that employs Varnish or view a detailed system log file.

Varnish in Semi-dedicated Servers

Varnish is offered as standard with all Linux semi-dedicated service offered by us and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any website that you host in your account. In case you are in need of more than that, you can increase the memory allowance. The memory itself is available in increments of 32 megabytes through the Control Panel’s Upgrades section. The exact same section will permit you to create more instances as well, if you’d like to use the Varnish platform with more websites. The two things can be ordered separately – you can cache the content of one popular website or use several different Internet sites with the default memory allocation. You can get the most out of the Varnish caching platform if you use a dedicated IP and you can order one with your semi-dedicated plan as well. The Hepsia Control Panel will grant you total control over the platform and, with no more than one single click, you’ll be able to clear the cache, to view a log file or to reboot an instance.

Varnish in VPS Servers

We provide Varnish with all Hepsia-equipped VPS servers, so in case you order a VPS with this web hosting Control Panel, you’ll be able to use the caching platform at no extra fee. The Varnish platform can utilize different amounts of memory for caching purposes depending on the particular sever setup that you have selected during the order process, but in any case, this amount will not be less than several hundred MB. This is quite enough to enhance the overall performance of a handful of resource-hungry Internet sites, so the better web page loading speeds and the lowered load on the Virtual Private Server will be perceivable. The result may not be distinguishable right away, since Varnish will need a certain amount of time to cache the site content that people browse, but soon after you activate it, you will witness its full potential. This caching platform will permit you to use a lower-end VPS server and to pay less money to get the same performance you’d get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers

All Linux dedicated service that are ordered with the custom-developed Hepsia web hosting Control Panel come with Varnish, which is among the pre-installed platforms that you’ll get with the machine. The Varnish platform can be set up and managed without efforts through the Hepsia Control Panel’s intuitive graphical interface and, with no more than a click, you can check a detailed system log, add or reboot an instance, clear the cached files associated with any site and much, much more. Soon after you enable the Varnish platform for a specific domain or sub-domain, it will begin caching the pages opened by your visitors and once it has cached enough content, you’ll observe a significantly faster website performance plus a decreased load on your dedicated machine. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the software platform for workload balancing purposes even if you run numerous Internet sites on your server.
