Varnish is a web accelerator tool, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any site, at times even by 100 percent, depending on the content itself. This tool is occasionally called an HTTP reverse proxy as well and is used to reduce the overall server load and to enhance the access speed for the site visitors. Each time a visitor accesses a page on a given site, the web browser request is taken care of by the web server and the requested content is returned as a response. If the Varnish accelerator is enabled, it caches the pages that the website visitor browses and in case any of them is loaded once more, it’s served by Varnish and not by the web server directly. The increase in the performance comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the website visitors. If any content is edited meanwhile, the cached pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Shared Hosting
You can use Varnish’s full potential and speed up your sites irrespective of the shared hosting package that you’ve picked and you can activate and configure the data caching platform with a few clicks using the simple-to-work-with GUI offered by our leading-edge Hepsia hosting Control Panel. In the meantime, you’ll be able to select two different things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 MB and is not linked to the number of instances, so you can order more instances with less memory and vice versa. If you’ve got plenty of content on a specific Internet site and you gain numerous website visitors, more system 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. Hepsia will offer you easy one-click controls for deleting or restarting any instance, for deleting the cache for each site and for viewing in-depth system logs.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting packages include Varnish by default, so you can make use of the web app accelerator tool and accelerate the load speed of any website that you host on our semi-dedicated servers. You’ll get 64 MB of system memory dedicated to the Varnish accelerator at no extra charge and you’ll be able to activate an instance with no more than a few clicks of the mouse via the Hepsia hosting Control Panel, which comes with the semi-dedicated plans. If you need more memory, the latter is available in increments of 32 MB in the Control Panel’s Upgrades section and it will be at your disposal instantaneously. You can also add more instances as a separate upgrade, so you can choose whether plenty of data will be cached for one site or whether the available memory will be utilized by different Internet sites. Hepsia will allow you to reboot or to disable any instance, to see the system log associated with it or to delete the cached data using single-click buttons. To get the most out of Varnish, you can set a dedicated IP for the websites that will use it.
Varnish in VPS
We offer Varnish with all of the Hepsia-managed Linux VPS packages, so if you get a VPS with this Control Panel, you’ll be able to use the caching platform at no extra cost. The Varnish platform can use different amounts of memory for content caching purposes based on the very Virtual Private Server package that you have picked during the server order process, but in any case, this amount won’t be less than several hundred MB. This is more than enough to boost the performance of a number of heavy Internet sites, so the better site browsing speeds and the reduced load on the machine will be discernible. The result may not be apparent immediately, as the Varnish platform will require some time to cache the content that users browse, but soon after you enable it, you’ll observe its full potential. This platform will permit you to use a less powerful VPS and to pay less cash to get the very same performance you’d get with a more powerful virtual machine without Varnish.
Varnish in Dedicated Hosting
In case you order a dedicated server with the Hepsia hosting Control Panel, you’ll acquire Varnish at no additional fee and you’ll have total control over it through an extremely easy-to-navigate graphical interface – you’ll be able to start, to stop or to reboot an instance, to check an elaborate system log, to clear the cached files associated with any website and much more. The Varnish platform will have several GB of memory at its disposal, so even if you’ve got traffic-hungry websites with plenty of visitors, you’ll notice the tremendously faster web page loading speeds and the less load on the dedicated server. This will become a fact soon after you begin using the Varnish platform, since it will need some time to cache the pages that people access. You can take full advantage of the platform’s potential if the websites that are using it use also a dedicated IP, but considering the fact that your dedicated server includes several IP addresses by default, you will not need to pay anything on top of the monthly charge for the server itself.
