Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, at times even by 100%, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to enhance the access speed for the site visitors. Whenever a visitor opens a page on a given Internet site, the browser request is processed by the web server and the requested content is returned as a reply. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and in case any of them is accessed again, it’s served by Varnish and not by the web server directly. The improvement in the overall performance is due to the fact that the accelerator handles the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the users. If any data is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time someone attempts to access them.
Varnish in Shared Web Hosting
In case you host your sites under a shared web hosting account with us, you will be able to activate Varnish with a few clicks from your Control Panel. The platform comes as an upgrade with all our shared web hosting packages and you can choose the number of the sites that will use it and the maximum storage space that will be used 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 tied to each other, so you can choose whether you want plenty of memory for one single large-size site or less memory for multiple smaller ones. You can take advantage of the full potential of Varnish if the websites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/reboot/disable an instance, clear the cached contents independently for each site that employs the Varnish platform or see an in-depth log file.
Varnish in Semi-dedicated Servers
Varnish is a feature, which comes as standard with all semi-dedicated plans that we’re offering and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached content storing purposes and you can use it with any Internet site that you host in the semi-dedicated server account. If you’re in need of more, you can increase the memory allowance. The memory itself is offered in increments of 32 MB through the Upgrades section of the Control Panel. The same Upgrades section will permit you to enable more instances as well, in case you wish to use the Varnish platform with multiple Internet sites. The two upgrades can be added separately – you can cache the content of a single traffic-heavy site or use several websites with the default memory allowance. You can get the most out of the Varnish caching platform if you have a dedicated IP and you can get one with your semi-dedicated server plan as well. The Hepsia Control Panel will give you full control over the caching platform and, with no more than one mouse click, you’ll be able to delete the cached data, to see a system log file or to restart an instance.
Varnish in VPS Servers
You can take advantage of Varnish with any of our VPS server packages at no additional cost, since the platform is pre-installed and is included by default. The one and only prerequisite is that the virtual server must be ordered with the Hepsia Control Panel, via which you will be able to activate Varnish for any of your Internet sites with just a couple of mouse clicks. Each package comes with a different amount of system memory for caching purposes, but you’ll get minimum several hundred MB, which is quite enough even for several regularly visited websites. Shortly after you activate Varnish, it’ll begin caching the content that your visitors browse, so you’ll notice the substantially faster page load speeds and the lowered load on your VPS in no time. The caching platform will allow you to use a less costly virtual machine, as you will not require that much power to guarantee the uninterrupted operation of your Internet sites even if you own heavy-traffic sites with multiple visitors. Maximum results are achieved if the sites which use Varnish use also a dedicated IP.
Varnish in Dedicated Servers
If you want the most powerful web hosting solution and you get one of the dedicated web hosting plans that we are offering, you will be able to use the Varnish content caching platform to enhance the overall performance of your websites at no extra cost on the condition that the server is ordered with our innovative Hepsia hosting Control Panel. Its simple-to-use interface will allow you to keep track of system processes, to delete the cached contents or to reboot any instance with a click. The smallest amount of memory that the Varnish platform can employ to cache content is three gigabytes, which is more than enough for an immense number of popular websites, so your server will be able to deal with a gigantic system load while your Internet site visitors are enjoying a seamless browsing experience. Since your dedicated machine will come with several dedicated IPs, you’ll be able to use Varnish’s maximum potential.
