Varnish is a web accelerator platform, which caches content for faster access. It is sometimes referred to as a caching HTTP reverse proxy as well and it works between a web server and its users. When a website visitor loads a given web page, the content is requested by the browser, and then the server processes this request and delivers the required information. If Varnish is enabled for a specific website, it will cache its pages at the very first request and if the visitor accesses a cached page again, the data will be delivered by the caching platform instead of the web server. The improved speed is an end result of the much faster response speed that the Varnish platform offers as compared with any web server software. At the same time, this doesn’t mean that the visitors will continue being served the very same content again and again, because any modification on any of the pages is reflected in the content that the Varnish platform stores in its memory.

Varnish in Cloud Hosting

Varnish comes as an optional upgrade with each Linux cloud hosting package and if you’d like to use it, you can add it to your hosting account via the Upgrades section in your Hepsia Control Panel. There are two different things that can be upgraded – the number of instances and the system memory. The first one depends on the number of the sites that you wish to use Varnish for and the second one, which is available in increments of 32 MB, shows the maximum amount of data that the platform can store at any particular time. The Hepsia Control Panel’s easy-to-work-with GUI will enable you to cancel or to restart any instance, to check comprehensive system logs or to erase the platform’s cache with just one mouse click. For best results, you can use a dedicated IP for the sites that will use the caching platform. With Varnish, your Internet site will load tremendously faster, meaning more satisfied users and potential customers.

Varnish in Semi-dedicated Hosting

The Varnish data caching platform is included in the default service set that you’ll acquire when you choose to host your websites in a semi-dedicated server account. You can configure it for any of your sites via our next-generation Hepsia hosting Control Panel. The default memory that Varnish can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. Since these two features are not tied to each other, you can use a few instances with the default memory or you can order more memory in increments of 32 megabytes and use all of it for one single website. Varnish performs best when you allocate a dedicated IP address to the websites that utilize its power. The Hepsia Control Panel will give you a simple way of rebooting any instance. In addition, you will be able to delete the cached content with just one mouse click.

Varnish in VPS Web Hosting

We provide Varnish with all Hepsia-equipped Linux VPS web hosting packages, so in case you buy a VPS with this hosting Control Panel, you’ll be able to take advantage of the data caching platform at no extra fee. The Varnish platform can use different amounts of system memory for content caching purposes depending on the very setup that you’ve chosen during the subscription process, but in any case, this amount won’t be less than several hundred megabytes. This is quite enough to optimize the work of several different regularly visited sites, so the better page load speeds and the reduced load on the VPS server will be discernible. The effect may not be distinguishable right away, as the Varnish platform will need a certain amount of time to cache the website content that people access, but soon after you activate it, you’ll observe its full capacity. This platform will allow you to use a less powerful VPS and to pay less cash to get the very same performance you would get with a more powerful virtual machine without Varnish.

Varnish in Dedicated Servers Hosting

All Linux dedicated servers hosting packages that are ordered with the custom-developed Hepsia hosting Control Panel include Varnish, which is one of the pre-installed platforms that you’ll get with the dedicated server. The Varnish content caching platform can be activated and managed with ease from the Hepsia Control Panel’s easy-to-work-with GUI and, with no more than one single click of the mouse, you can see a comprehensive log, create or restart an instance, clear the cached content for any website and much, much more. Shortly after you set up the Varnish platform for a certain domain or sub-domain, it will start caching the webpages loaded by the website visitors and as soon as it has cached enough web content, you will observe a considerably faster site performance in addition to a lowered load on the server. With Varnish-dedicated system memory starting at 3 gigabytes, you will be able to use the platform for workload balancing purposes even if you host an immense number of Internet sites on the dedicated machine.
