Varnish is a web accelerator platform, which caches information for the sake of faster access. It’s sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and a web browser. When a site visitor loads a certain web page, its content is requested by the Internet browser, and then the server processes this browser request and sends back the needed data. If Varnish is enabled for a specific website, it will cache the pages at the first visit and if the visitor opens a cached page for a second time, the data will be delivered by the caching platform instead of the server. The boosted speed is an end result of the substantially faster response speed that the Varnish platform offers as compared with any web server software. Of course, this does not mean that the site visitors will continue being served the very same content again and 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 Shared Hosting

If you host your websites in a shared hosting account with us, you will be able to add Varnish with a couple of clicks of the mouse through your hosting Control Panel. The data caching platform comes as an upgrade with all our hosting plans and you can select the number of the sites that will use it and the total storage space that will be used for the cached content. 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 directly tied to each other, so you can decide if you need plenty of memory for a single large-size website or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP. Using the Control Panel, you can quickly start/reboot/discontinue an instance, delete the cached contents independently for each website that uses the Varnish platform or see an in-depth system log file.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting include Varnish by default, so you can take advantage of the web app accelerator tool and accelerate any website that you host on our semi-dedicated servers. You’ll get 64 MB of memory particularly for the Varnish accelerator at no additional charge and you will be able to create an instance with no more than a couple of clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated server plans. In case you want more memory, the latter is offered in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be available to you momentarily. You can also add more instances as an upgrade, so you can choose whether plenty of data will be cached for a single website or if the available memory will be used by multiple Internet sites. The Hepsia Control Panel will allow you to restart or to disable any instance, to check the system log for it or to clear the cached files using single-click controls. To take full advantage of Varnish, you can set a dedicated IP address for the websites which will employ it.

Varnish in VPS Hosting

We offer Varnish with all of the Hepsia-equipped Linux VPS hosting, so in case you get a server with this web hosting Control Panel, you will be able to take full advantage of the caching platform at no additional charge. Varnish can use different amounts of system memory for caching purposes depending on the particular sever setup that you’ve selected during the order process, but in any case, this amount won’t be less than several hundred megabytes. This is quite enough to enhance the performance of a handful of traffic-intensive sites, so the faster web page load speeds and the lowered load on the VPS will be discernible. The result may not be visible immediately, as Varnish will need a certain amount of time to cache the website content that people access, but soon after you set it up, you will witness its full capacity. This platform will allow you to use a less powerful Virtual Private Server and to give less cash to get the exact same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Web Hosting

All Linux dedicated web hosting that are ordered with the in-house built Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you’ll get with the dedicated server. The Varnish platform can be configured and administered without efforts via the Hepsia Control Panel’s easy-to-work-with graphical interface and, with no more than one single click of the mouse, you can browse an elaborate log, add or reboot an instance, clear the cached data for any site and much, much more. Shortly after you set up the Varnish platform for a specific domain or subdomain, it will begin caching the pages browsed by the site visitors and as soon as it has cached enough content, you will perceive a tremendously better website performance and a lowered load on your dedicated machine. With Varnish-dedicated memory starting at 3 GB, you will be able to use the software platform for workload balancing purposes even if you run an enormous number of Internet sites on your dedicated server.
