Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, sometimes even by 100 percent, based on the content. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to increase the browsing speed for the site visitors. Anytime a visitor accesses a page on a specific Internet site, the web browser request is handled by the web server and the requested info is sent as a response. If Varnish is enabled, it caches the pages that the site visitor browses and if any of them is loaded once more, it is delivered by Varnish and not by the server directly. The performance increase comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which results in much faster browsing speeds for the visitors. If any data is updated meanwhile, the cached pages will also be ‘refreshed’ the next time someone opens them.

Varnish in Web Hosting

If you host your Internet sites in a web hosting account with us, you will be able to add Varnish with a few clicks from your Control Panel. The platform comes as an optional upgrade with all our packages and you can select how many sites will use it and the maximum storage space that will be available for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they aren’t directly linked to each other, so you can decide if you need lots of memory for a single large website or less memory for several smaller ones. You can use the full potential of Varnish if the sites use a dedicated IP address. With the Control Panel, you can swiftly start/restart/remove an instance, clear the cached files independently for each site which uses Varnish or check a detailed log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is included by default with all semi-dedicated servers offered by us and you can use it for workload distribution 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 Internet site that you host in your account. If you are in need of more than that, you can increase the memory allocation. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same Upgrades section will allow you to activate more instances too, if you want to use the Varnish platform with multiple websites. The two upgrades can be added independently – you can cache the content of one traffic-heavy website or run a number of sites with the default memory quota. You can get the most out of the Varnish platform if you use a dedicated IP and you can get one with your semi-dedicated server plan as well. The Hepsia Control Panel will give you total control over the caching platform and, with no more than one single click, you’ll be able to clear the cached data, to see a log or to reboot an instance.

Varnish in VPS Servers

The Varnish platform is included by default with each of the VPS servers that we offer on the condition that the virtual machine is ordered with the Hepsia hosting Control Panel, so you can improve the work of your sites with only a few mouse clicks. The more powerful the plan, the more memory Varnish will have at its disposal, but even with a less powerful plan, the caching platform will be able to utilize several hundred MB, so even if you manage several websites, you will notice an immense decrease in the server load and a considerably better page load speed. The Varnish platform will need 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 pluses of employing Varnish is that a lower-end and less expensive package will accomplish the same job as a more expensive one without the platform, so not only will your sites work substantially better, but you’ll also save a certain amount of money.

Varnish in Dedicated Servers

If you need a powerful hosting solution and you buy any of the dedicated servers that we’re offering, you will be able to use Varnish to improve the performance of your Internet sites at no extra charge on the condition that the dedicated server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-use graphical interface will allow you to keep track of platform processes, to clear the cached files or to reboot any instance with one single mouse click. The minimum amount of system memory that Varnish can use to cache Internet site content is 3 GB, which is quite enough for a vast number of large-size websites, so your dedicated server will be able to cope with an enormous system load while your website visitors are having a smooth browsing experience. Since your dedicated server will include several different dedicated IPs, you will be able to use Varnish’s maximum potential.
