Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any website, sometimes even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to decrease the overall load on the server and to improve the access speed for the site visitors. Whenever a visitor opens a page on a particular website, the web browser request is processed by the web server and the requested data is sent as a reply. If Varnish is activated, it caches the web pages that the website visitor opens and in case any of them is accessed again, it’s delivered by Varnish and not by the server directly. The boost in the overall performance is due to the fact that the accelerator processes the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the visitors. In case any data is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Shared Website Hosting

Varnish comes as an optional upgrade with all our shared website hosting services. You can add it to your account from the Hepsia hosting Control Panel, which is available with all shared web hosting packages and you will get a quite easy-to-use graphical interface, which will grant you complete control over the content caching platform. Using one-click fast-access buttons, you can restart or turn off any of the instances, i.e. Varnish will no longer be enabled for a specific site. You can also view an elaborate log or erase the cache for any of the websites. When you add Varnish to your hosting plan, you’ll be able to choose the maximum amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the websites that will use Varnish. This will permit you to take full advantage of your sites and to have many gratified website visitors.

Varnish in Semi-dedicated Hosting

The Linux semi-dedicated hosting that we’re offering will allow you to employ Varnish as soon as your brand new account is active, since the platform comes by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is enabled, so you can make use of this workload distribution software as soon as you launch your site. If you need more memory, you can add 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be assigned to your semi-dedicated server immediately. You can also increase the number of the Internet sites that employ Varnish, or the so-called ‘instances’, which are not linked directly to the amount of system memory that you use, which suggests that you’ll have more flexibility. The Varnish platform will noticeably lower the load on the server caused by your sites, so your site visitors can enjoy fast-opening web pages. You’ll be able to manage the Varnish platform effortlessly through the Control Panel using quick-access buttons. You’ll be able to start/deactivate any of the instances that you have, to clear the cached content for any of your sites or to check system logs.

Varnish in VPS

You can use Varnish with all our virtual private server packages at no additional fee, as the platform is pre-installed and is included by default. The one and only condition is that the Virtual Private Server must come with the Hepsia Control Panel, through which you’ll be able to activate Varnish for any of your websites with only a few clicks. Each VPS plan features a different amount of system memory for content caching purposes, but you’ll have minimum several hundred MB, which is quite sufficient even for multiple large-size websites. Shortly after you enable the Varnish platform, it will begin caching the content that your visitors access, so you will notice the tremendously better web page loading times and the less load on the VPS very soon. The caching platform will permit you to use a less high-priced virtual machine, as you won’t need that much power to ensure the uninterrupted operation of your sites even if you run traffic-heavy websites with numerous visitors. Optimal results are achieved if the sites that use Varnish use also a dedicated IP address.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish platform at no additional charge and you will have total control over it through a rather simple-to-use GUI – you’ll be able to start, to remove or to restart an instance, to see an exhaustive log, to clear the cache for any website and much, much more. Varnish will have several GB of virtual memory at its disposal, so even if you’ve got traffic-heavy Internet sites with a lot of visitors, you’ll notice the much faster site loading speeds and the reduced load on the server. This will become a fact shortly after you begin using Varnish, as it will need a certain amount of time to cache the site content that visitors request. You can take full advantage of the platform’s capability if the Internet sites that are using it also use a dedicated IP, 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 fee for the server itself.
