Varnish is a web app accelerator platform, which caches content for the sake of faster access. It is sometimes called an HTTP reverse proxy as well and it works between a web server and its users. When a visitor opens a particular page, the content is requested by the web browser, and then the server handles this browser request and delivers the necessary information. If Varnish is activated for a given website, it will cache its pages at the first visit and if the visitor accesses a cached page once more, the content will be delivered by the accelerator platform and not by the web server. The increased load speed is an end result of the much faster response speed that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the users will keep 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 Website Hosting

In case you host your Internet sites in a website hosting account with us, you will be able to add Varnish with a few mouse clicks via your Control Panel. The platform is offered as an upgrade with all our plans and you can choose the number of the websites that will use it and the maximum storage space that will be used for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they aren’t directly linked to each other, so you can decide if you need lots of memory for a single large website or less memory for multiple smaller ones. You can unlock the full potential of the Varnish caching platform if the websites use a dedicated IP. Using the hosting Control Panel, you can effortlessly start/reboot/discontinue an instance, clear the cached content independently for each site which uses Varnish or check an in-depth system log file.

Varnish in Semi-dedicated Hosting

The Varnish data caching platform is included in the basic set of services that you’ll obtain if you choose to host your websites under a semi-dedicated server account. You can configure it for any of your websites through our innovative Hepsia hosting Control Panel. The default system memory that the Varnish caching platform can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform at the same time. Since these two things are not linked to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single website. The Varnish caching platform performs best when you assign a dedicated IP to the websites that utilize its power. Hepsia will give you an easy means of rebooting any instance. In addition, you’ll be able to delete the cached data with just one single click.

Varnish in VPS Web Hosting

You can take advantage of Varnish with each of our virtual private server plans at no extra charge, since the platform is pre-installed and is included by default. The sole requirement is that the VPS must come with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your sites with just a few mouse clicks. Each VPS package offers a different amount of system memory for content caching purposes, but you’ll get at least several hundred MB, which is sufficient enough even for multiple traffic-hungry sites. Shortly after you set up Varnish, it will begin caching the content that your website visitors request, so you will notice the much better webpage load times and the reduced load on your VPS very soon. The caching platform will permit you to use a less expensive virtual server, as you won’t require that much power to sustain the correct operation of your websites even if you own larger sites with lots of visitors. Maximum results are achieved if the websites which use the Varnish platform also use a dedicated IP.

Varnish in Dedicated Servers Hosting

If you need the most powerful website hosting solution and you obtain one of the Linux dedicated hosting services that we offer, you’ll be able to use the Varnish content caching platform to improve the overall performance of your websites at no extra cost as long as the server is ordered with our avant-garde Hepsia hosting Control Panel. Its simple-to-work-with GUI will allow you to keep an eye on platform processes, to delete the cached content or to reboot any instance with a click. The minimal amount of system memory that Varnish can employ to cache Internet site content is 3 GB, which is quite enough for an immense collection of heavy sites, so your server will be able to handle a massive system load while your Internet site visitors are enjoying a seamless web browsing experience. Since your dedicated server will come with several different dedicated IP addresses, you’ll be able to use Varnish’s full potential.
