Varnish is a data caching platform, which is sometimes called a caching HTTP reverse proxy. It’s a web app accelerator tool that can accelerate the speed of a site by up to 1000%, depending on its content. Every time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the web browser request from the visitor is not processed by the server and the web page will open substantially faster, as Varnish can serve content many times faster than any web server software. The result will be a substantially faster loading site, which leads to a greatly improved visitor experience. In case any of the cached pages is updated on the live website, the info that Varnish saves in its system memory is ‘refreshed’ too, so the site visitors will never end up seeing old data.

Varnish in Cloud Web Hosting

You can use Varnish’s potential and optimize the speed of your sites irrespective of the cloud web hosting plan that you’ve chosen and you can activate and configure the data caching platform with several clicks from the intuitive interface offered by our cutting-edge Hepsia Control Panel. In the meantime, you’ll be able to choose two separate things – how many Internet sites will employ the Varnish platform, i.e. the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can add more instances and less memory and vice versa. If you have plenty of content on a specific website and you gain lots of website visitors, more memory will give you better results. You may also consider using a dedicated IP address for the sites that will use the Varnish caching platform. The Hepsia Control Panel will offer you easy 1-click controls for removing or restarting any instance, for clearing the cache for each Internet site and for viewing in-depth logs.

Varnish in Semi-dedicated Servers

Varnish is included by default with all Linux semi-dedicated hosting plans that we are offering and you can use it for load distribution purposes. It is available in your Hepsia Control Panel. The data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can use it with any website that you host in your semi-dedicated account. In case you’re in need of more than that, you can increase the memory allowance. The memory itself is offered in increments of 32 MB through the Control Panel’s Upgrades section. The same section will allow you to activate more instances too, in case you wish to use the Varnish caching platform with more Internet sites. The two upgrades can be ordered independently – you can cache the content of a single resource-intensive site or run several different sites with the default memory allowance. You can take full advantage of the Varnish caching platform in case you have a dedicated IP address and you can order one with your semi-dedicated package as well. Hepsia will grant you total control over the platform and, with no more than one mouse click, you’ll be able to clear the cached files, to check a system log or to restart an instance.

Varnish in VPS Servers

You can use Varnish with each of our VPS server plans at no additional fee, since the data caching platform is pre-installed and is included by default. The sole precondition is that the server must come with the Hepsia Control Panel, via which you will be able to set up Varnish for any of your Internet sites with just a few mouse clicks. Each plan includes 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 busy sites. Soon after you activate Varnish, it’ll begin caching the content that your visitors access, so you’ll notice the considerably better webpage loading times and the reduced load on the Virtual Private Server very soon. The Varnish caching platform will allow you to use a less costly Virtual Private Server, as you will not need that much power to sustain the proper operation of your Internet sites even if you manage resource-consuming Internet sites with numerous visitors. Optimum results are achieved if the sites which use the Varnish caching platform use also a dedicated IP.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you will acquire Varnish at no extra charge and you will have full control over it through a truly intuitive graphical interface – you’ll be able to start, to deactivate or to restart an instance, to see an exhaustive log, to clear the cached data associated with any site and much more. The Varnish platform will have several GB of memory at its disposal, so even if you host large websites with a lot of visitors, you will notice the substantially faster page loading speeds and the less server load. This will become a fact soon after you begin using the Varnish platform, as it will require a certain amount of time to cache the content that visitors request. You can take full advantage of the platform’s potential if the Internet sites that are using it use also a dedicated IP address, but considering the fact that your dedicated server comes with several IP addresses by default, you won’t have to pay anything on top of the monthly fee for the machine itself.
