Varnish is a web app accelerator tool, which has been gaining a lot of popularity lately, because it can increase the speed of any site, sometimes even by one hundred percent, depending on the content. This tool is sometimes called an HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to improve the browsing speed for the website visitors. Each time a visitor opens a page on a particular Internet site, the web browser request is handled by the web server and the requested information is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor opens and in case any of them is loaded for a second time, it’s fetched by Varnish and not by the web server directly. The improvement in the performance is due to the fact that the accelerator processes the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the users. If any data is changed in the meantime, the cached web pages will also be updated the next time someone tries to access them.

Varnish in Hosting

You can unleash Varnish’s potential and improve the load speed of your websites regardless of the hosting plan that you’ve chosen and you can enable and configure the content caching platform with several mouse clicks using the user-friendly graphical interface offered by our cutting-edge Hepsia hosting Control Panel. During the process, you will be able to choose two separate things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much content will be cached, in other words – the amount of memory. The latter comes in increments of 32 MB and is not linked to the number of instances, so you can use more instances with less memory and the other way around. If you’ve got a lot of content on a given Internet site and you receive a lot of website visitors, more memory will give you a better result. You may also consider employing a dedicated IP for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will offer you simple 1-click controls for terminating or rebooting any instance, for erasing the cache for each Internet site and for checking elaborate logs.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is offered as standard with all Linux semi-dedicated servers that we’re offering and you can use it for load balancing purposes. It’s available in your Hepsia hosting Control Panel. The content caching platform comes with 64 MB of system memory for cached content storing purposes and you can employ it with any website that you host in your account. If you need more than that, you can increase the system memory quota. The memory itself is available in increments of 32 megabytes through the Control Panel’s Upgrades section. The same Upgrades section will enable you to activate more instances as well, if you would like to use the Varnish platform with more sites. The two things can be added separately – you can cache the content of one single popular website or use several Internet sites with the default memory quota. You can get the most out of the Varnish platform if you have a dedicated IP address and you can order one with your semi-dedicated server plan as well. Hepsia will grant you complete control over the platform and, with no more than a click, you will be able to clear the cached data, to view a system log file or to restart an instance.

Varnish in VPS Servers

You can take advantage of Varnish with each of our VPS server packages at no additional fee, as the content caching platform is pre-installed and is included 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 websites with only a few clicks of the mouse. Each VPS plan includes a different amount of system memory for data caching purposes, but you’ll have at least several hundred MB, which is quite enough even for multiple resource-consuming websites. Shortly after you enable Varnish, it’ll begin caching the content that your site visitors open, so you will notice the significantly better page loading speeds and the less load on the virtual server very soon. Varnish will allow you to use a less pricey VPS server, as you will not require that much power to guarantee the proper operation of your sites even if you’ve got high-demand Internet sites with lots of visitors. Optimum results are accomplished if the sites that use the Varnish caching platform use also a dedicated IP.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia Control Panel, you’ll acquire Varnish at no additional fee and you’ll have full control over it through an exceptionally easy-to-work-with graphical interface – you’ll be able to start, to terminate or to reboot an instance, to see an exhaustive system log, to delete the cached files for any Internet site and much more. The Varnish platform will have several GB of memory at its disposal, so even if you own popular sites with a huge number of visitors, you’ll notice the significantly better web page load times and the less load on your dedicated machine. This will become a fact shortly after you begin using Varnish, since it will need a certain amount of time to cache the content that users browse. You can take full advantage of the platform’s capability in case the websites that are using it also use a dedicated IP address, but owing to the fact that your dedicated server includes several IP addresses by default, you will not need to pay anything on top of your monthly fee for the machine itself.
