Varnish is a web app accelerator platform, which caches content for faster access. It is occasionally referred to as a caching HTTP reverse proxy too and it interacts between a web server and a web browser. When a visitor loads a specific web page, the content is requested by the Internet browser, and then the server processes this request and returns the needed info. If Varnish is enabled for a particular site, it will cache its pages on the first request and if the visitor visits a cached page once more, the data will be delivered by the caching platform instead of the server. The accelerated load speed is a result of the significantly faster response speed that Varnish offers as compared with any server software. At the same time, this does not mean that the visitors will continue being served the very same content over and over again, since any change on any of the web pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Website Hosting

If you host your Internet sites under a website hosting account with us, you’ll be able to add Varnish with several mouse clicks through your hosting Control Panel. The data caching platform is offered as an optional upgrade with all our web hosting packages and you can choose how many websites will use it and the maximum storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not linked directly to each other, so you can decide whether you need plenty of memory for one large-scale site or less memory for multiple smaller ones. You can make use of the full potential of Varnish if the sites use a dedicated IP. With the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, clear the cached data independently for each website that uses Varnish or check an exhaustive log file.

Varnish in Semi-dedicated Servers

All our semi-dedicated servers include Varnish by default, so you can take advantage of the web accelerator and accelerate any site that you host on our platform. You will get 64 megabytes of memory exclusively for Varnish at no extra charge and you can add an instance with no more than a couple of clicks via the Hepsia hosting Control Panel, which is included with the semi-dedicated plans. If you want more memory, the latter is available in increments of 32 MB through the Upgrades section of the Control Panel and it will be at your disposal straight away. You can also add more instances as a separate upgrade, so you can decide whether lots of content will be cached for a single website or if the memory will be used by multiple websites. Hepsia will allow you to restart or to remove any instance, to see the system log associated with it or to delete the cached data using 1-click buttons. To get the most out of Varnish, you can allocate a dedicated IP address to the sites that will employ it.

Varnish in VPS Servers

You can take advantage of Varnish with all our VPS server plans at no extra cost, as the data caching platform is pre-installed and is included by default. The one and only precondition is that the server must come with the Hepsia hosting Control Panel, via which you will be able to set up Varnish for any of your websites with only a few mouse clicks. Each package features a different amount of system memory for data caching purposes, but you will get minimum several hundred MB, which is quite enough even for several traffic-consuming Internet sites. Soon after you enable Varnish, it’ll begin caching the content that your visitors browse, so you will notice the much faster web page loading times and the reduced load on your virtual server very soon. The caching platform will permit you to use a less pricey Virtual Private Server, since you will not require that much power to ensure the correct operation of your websites even if you own large-sized Internet sites with many visitors. Optimum results are accomplished if the sites which use Varnish also use a dedicated IP.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish caching platform at no extra fee and you’ll exert full control over it via an incredibly easy-to-work-with graphical interface – you will be able to start, to remove or to reboot an instance, to browse an exhaustive log, to clear the cached data for any Internet site and much more. The Varnish caching platform will have several GB of virtual memory at its disposal, so even if you run busy sites with numerous visitors, you’ll notice the considerably better web page load times and the less load on your dedicated server. This will happen shortly after you begin using the Varnish platform, as it will need some time to cache the site content that users access. You can take full advantage of the platform’s potential if the Internet sites that are using it also use a dedicated IP address, but considering the fact that your server comes with a couple of IP addresses by default, you will not have to pay anything on top of your monthly fee for the machine itself.
