Varnish is a data caching platform, which is occasionally referred to as a caching HTTP reverse proxy. It is a web application accelerator that can increase the load speed of a site by up to one thousand percent, depending on its content. Each time a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor loads it again. Thus, the web browser request from the visitor is not processed by the server and the web page will open considerably faster, as the Varnish caching platform can deliver data many times faster than any server software. The result is a significantly faster loading page, which leads to an immensely improved visitor experience. If any of the cached webpages is updated on the live website, the content that Varnish saves in its system memory is ‘refreshed’ too, so the website visitors will not end up seeing old information.
Varnish in Website Hosting
You can unlock Varnish’s potential and optimize the speed of your sites irrespective of the website hosting plan that you have chosen and you can add and set up the platform with a couple of clicks from the easy-to-use interface offered by our advanced Hepsia hosting Control Panel. During the process, you’ll be able to select two separate things – how many websites will use the Varnish platform, i.e. the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances and less memory and the other way around. If you’ve got plenty of content on a given Internet site and you win many site visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with simple 1-click buttons for removing or rebooting any instance, for erasing the cache for each Internet site and for viewing elaborate system logs.
Varnish in Semi-dedicated Servers
All our Linux semi-dedicated service include Varnish by default, so you can take advantage of the web accelerator and speed up any website that you host on our platform. You’ll get 64 megabytes of memory particularly for Varnish at no additional cost and you’ll be able to enable an instance with no more than a few mouse clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated plans. In case you want more memory, the latter is offered in increments of 32 MB in the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as an upgrade, so you can choose if lots of data will be cached for a single site or if the memory will be used by multiple Internet sites. Hepsia will permit you to reboot or to discontinue any instance, to view the system log for it or to clear the cached files using single-click controls. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the Internet sites that will employ it.
Varnish in VPS Servers
You can take advantage of Varnish with all our VPS server packages at no additional cost, since the caching platform is pre-installed and is offered by default. The one and only prerequisite is that the VPS server must come 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 mouse clicks. Each Virtual Private Server plan features a different amount of system memory for caching purposes, but you’ll have minimum several hundred MB, which is enough even for several busy Internet sites. Shortly after you activate the Varnish platform, it will start caching the content that your site visitors request, so you’ll notice the much faster website loading speeds and the lowered server load in no time. The platform will permit you to use a less high-priced virtual machine, as you won’t require that much power to ensure the proper operation of your websites even if you run resource-heavy sites with many visitors. Best results are accomplished if the Internet sites that use Varnish also use a dedicated IP address.
Varnish in Dedicated Servers
In case you order a dedicated server with the Hepsia Control Panel, you will obtain Varnish at no additional fee and you will have complete control over it through a pretty intuitive graphical interface – you will be able to start, to stop or to restart an instance, to view a detailed log, to clear the cached data associated with any site and much, much more. The Varnish platform will have several GB of system memory at its disposal, so even if you have resource-hungry Internet sites with a huge number of visitors, you’ll notice the much better website loading times and the reduced load on your server. This will become a fact shortly after you begin using the Varnish platform, as it will require some time to cache the website content that visitors access. You can get the most out of the platform’s capacity in case the Internet sites that are using it also use a dedicated IP address, but since your dedicated server includes a couple of IP addresses by default, you won’t have to pay anything on top of your monthly fee for the server itself.
