Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the loading speed of any site, sometimes even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to boost the access speed for the website visitors. Whenever a visitor accesses a page on a certain website, the browser request is taken care of by the web server and the requested content is returned as a response. If Varnish is activated, it caches the pages that the visitor browses and in case any of them is opened for a second time, it’s delivered by Varnish and not by the server directly. The performance improvement is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is updated in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody tries to access them.

Varnish in Shared Hosting

You can use Varnish’s full potential and accelerate your sites’ speed irrespective of the shared hosting package that you’ve chosen and you can enable and configure the content caching platform with a couple of clicks of the mouse via the intuitive graphical interface offered by our cutting-edge Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two different things – how many sites will employ Varnish, in other words – the number of instances, and how much data will be cached, i.e. the amount of memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances and less memory and vice versa. If you have a lot of content on a certain website and you win plenty of site visitors, more memory will guarantee you better results. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will offer you simple one-click buttons for stopping or rebooting any instance, for deleting the cache associated with each website and for seeing comprehensive system logs.

Varnish in Semi-dedicated Servers

Varnish comes as standard with all semi-dedicated plans offered by our company and you can use it for load distribution purposes. It is available in your Hepsia hosting Control Panel. The platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any site that you host in the semi-dedicated server account. In case you need more than that, you can increase the system memory allocation. The memory itself is offered in increments of 32 MB through the Upgrades section of the Control Panel. The same section will permit you to enable more instances too, in case you wish to use the Varnish platform with more Internet sites. The two things can be ordered separately – you can cache the content of a single large site or run several sites with the default memory allocation. You can take full advantage of Varnish in case you have a dedicated IP address and you can order one with your semi-dedicated plan as well. Hepsia will grant you total control over the caching platform and, with no more than one single click of the mouse, you’ll be able to clear the cached contents, to see a system log or to reboot an instance.

Varnish in VPS Servers

Varnish is included by default with all VPS servers offered by our company given that the Virtual Private Server is ordered with the Hepsia hosting Control Panel, so you can boost the performance of your sites with only a couple of clicks. The more powerful the plan, the more system memory Varnish will have at its disposal, but even with a less powerful package, the caching platform will be able to utilize several hundred megabytes, so even if you own several sites, you’ll notice an enormous reduction in the server load and a much better web page loading speed. The Varnish platform will have to work for a while while the users browse the web pages and once the site content has been cached, you’ll observe the results. One of the pros of using Varnish is that a less powerful and less pricey VPS plan will accomplish the same job as a more expensive one without the platform, so not only will your Internet sites perform considerably better, but you’ll also spare a certain amount of money.

Varnish in Dedicated Servers

If you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire the Varnish platform at no extra charge and you’ll have complete control over it through a pretty easy-to-work-with interface – you will be able to start, to deactivate or to reboot an instance, to view an elaborate system log, to clear the cached data for any site and much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you host resource-hungry websites with a huge number of visitors, you will notice the significantly faster web page load times and the decreased load. This will happen shortly after you start using the Varnish platform, as it will require a certain amount of time to cache the site content that people access. You can take full advantage of the platform’s capability in case the sites that are using it also use a dedicated IP address, but since your dedicated server comes with several IPs by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
