Varnish is a web app accelerator, which has been gaining a lot in popularity in recent years, as it can increase the loading speed of any site, at times even by one hundred percent, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to enhance the browsing speed for the website visitors. Anytime a visitor opens a page on a certain site, the web browser request is handled by the web server and the requested information is sent as a response. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is accessed again, it is delivered by Varnish and not by the server directly. The improvement in the overall performance is due to the fact that the accelerator processes the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody tries to open them.

Varnish in Cloud Hosting

If you host your sites in a cloud hosting account with us, you’ll be able to add Varnish with several clicks of the mouse from your Control Panel. The platform is available as an optional upgrade with all our hosting plans and you can choose how many sites will use it and the maximum storage space that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not directly linked to each other, so you can decide if you want a lot of memory for a single large website or less memory for multiple smaller ones. You can use the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the Control Panel, you can quickly start/restart/cancel an instance, delete the cached data independently for each site that employs Varnish or see a detailed log file.

Varnish in Semi-dedicated Servers

The Linux semi-dedicated plans that we’re offering will permit you to use Varnish once your new semi-dedicated account has been created, as the platform is offered by default. 64 megabytes of system memory will be allocated to Varnish the second your account is activated, so you can take advantage of this load distribution software as soon as you launch your site. In case you’re in need of more system memory, you can get 32 MB at a time from the Hepsia Control Panel’s Upgrades section and it will be allocated to your semi-dedicated server right away. You can also increase the number of the Internet sites that use Varnish, or the so-called ‘instances’, which are not bound directly to the amount of system memory that you use, which goes to say that you will have more freedom. The Varnish platform will substantially lower the load caused by your websites, so your website visitors can enjoy fast-opening web pages. You’ll be able to manage Varnish without efforts via your Hepsia Control Panel using quick-access controls. You’ll be able to start/remove any of the instances that you have, to delete the cached content associated with any of your Internet sites or to view system log files.

Varnish in VPS Servers

You can use Varnish with any of our VPS server packages at no additional cost, since the caching platform is pre-installed and is offered by default. The sole prerequisite is that the virtual server must be ordered with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your websites with just a few clicks of the mouse. Each VPS plan offers a different amount of system memory for content caching purposes, but you will have minimum several hundred MB, which is sufficient enough even for several resource-intensive websites. Shortly after you set up Varnish, it will start caching the content that your site visitors access, so you’ll notice the substantially better website load speeds and the less load on the virtual machine in no time. The Varnish platform will permit you to use a less high-priced Virtual Private Server, since you won’t require that much power to sustain the proper operation of your websites even if you manage traffic-heavy sites with many visitors. Optimal results are accomplished if the websites that use Varnish use also a dedicated IP address.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish content caching platform at no extra cost and you’ll exert full control over it through an extremely time and effort saving interface – you will be able to start, to stop or to restart an instance, to check an elaborate log, to clear the cache for any Internet site and much, much more. The Varnish platform will have several GB of memory at its disposal, so even if you own traffic-intensive Internet sites with an enormous number of visitors, you’ll notice the substantially faster web page loading times and the reduced load on your dedicated server. This will happen shortly after you begin using Varnish, since it will need some time to cache the pages that users request. You can make the most of the platform’s capabilities if the websites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes several IPs by default, you will not need to pay anything on top of the monthly charge for the machine itself.
