Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any site, sometimes even by 100 percent, depending on the content. This tool is sometimes referred to as an HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the access speed for the website visitors. Whenever a visitor opens a page on a given website, the browser request is handled by the web server and the requested data is delivered as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor browses and if any of them is accessed once more, it is served by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator processes the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the users. If any content is modified meanwhile, the cached web pages will also be updated the next time someone tries to open them.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with each and every shared hosting and if you wish to use it, you can add it to your shared account via the Upgrades section in your Hepsia Control Panel. There’re two separate features that can be upgraded – the number of instances and the memory. The first one pertains to the number of the sites that you’d like to employ Varnish for and the second one, which is available in increments of 32 megabytes, displays the total amount of data that the data caching platform can cache at any particular moment. The Hepsia Control Panel’s user-friendly interface will enable you to terminate or to restart any instance, to view exhaustive logs or to get rid of the platform’s cache with just click of the mouse. For best results, you can employ a dedicated IP address for the websites that will use the caching platform. With Varnish, your Internet site will open much faster, which means more pleased website visitors and prospective customers.
Varnish in Semi-dedicated Hosting
All our semi-dedicated hosting come with Varnish by default, so you can make full use of the web application accelerator tool and increase the speed of any website that you host on our semi-dedicated servers. You’ll get 64 MB of system memory dedicated to the Varnish accelerator at no extra charge and you will be able to create an instance with no more than a couple of mouse clicks through the Hepsia Control Panel, which is included with the semi-dedicated server packages. If you need more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be available to you right away. You can also add more instances as an upgrade, so you can decide if lots of data will be cached for a single website or whether the available memory will be utilized by multiple Internet sites. Hepsia will enable you to reboot or to terminate any instance, to view the system log file for it or to clear the cached files using one-click buttons. To get the most out of Varnish, you can allocate a dedicated IP to the Internet sites which will use it.
Varnish in VPS
You can use Varnish with all our virtual private server plans at no additional charge, as the caching platform is pre-installed and is available by default. The only requirement is that the virtual machine must be ordered with the Hepsia hosting Control Panel, via which you will be able to activate Varnish for any of your Internet sites with just a few clicks. Each package offers a different amount of memory for content caching purposes, but you will have at least several hundred megabytes, which is enough even for several traffic-heavy Internet sites. Soon after you set up Varnish, it’ll begin caching the content that your site visitors request, so you will notice the considerably better page load speeds and the reduced load on the VPS server in no time. The caching platform will permit you to use a less high-priced Virtual Private Server, as you won’t require that much power to sustain the proper operation of your websites even if you run large-scale sites with many visitors. Optimum results are accomplished if the sites which use Varnish use also a dedicated IP.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish caching platform at no extra fee and you will have complete control over it via a truly intuitive interface – you’ll be able to start, to disable or to reboot an instance, to see an exhaustive system log, to clear the cache associated with any Internet site and much, much more. The Varnish platform will have several GB of system memory at its disposal, so even if you host regularly visited Internet sites with a large number of visitors, you will notice the tremendously better site loading times and the lowered load on the dedicated server. This will become a fact soon after you start using Varnish, as it will need a certain amount of time to cache the site content that visitors access. You can make the most of the platform’s capabilities if the websites that are using it use also a dedicated IP address, but due to the fact that your server includes several IPs by default, you won’t have to pay anything on top of your monthly fee for the server itself.
