Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the speed of any Internet site, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to decrease the overall server load and to enhance the browsing speed for the site visitors. Each time a visitor accesses a page on a specific website, the web browser request is taken care of by the web server and the requested content is sent as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor opens and if any of them is opened once again, it is fetched by Varnish and not by the server directly. The increase in the performance is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the visitors. If any data is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time someone opens them.
Varnish in Cloud Web Hosting
Varnish comes as an optional upgrade with each of our Linux cloud web hosting
. You can add it to your account through the Hepsia Control Panel, which comes with all shared web hosting packages and you’ll get a really simple-to-use interface, which will grant you complete control over the caching platform. Using one-click quick-access controls, you can reboot or terminate any of the instances, in other words – Varnish will no longer work for a certain site. You can also check a comprehensive log or erase the cache associated with any of the sites. When you add Varnish to your web hosting package, you will be able to select the maximum amount of system memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can allocate a dedicated IP to the websites that will use Varnish. This will allow you to get the most out of your websites and to have many pleased site users.
Varnish in Semi-dedicated Servers
The Varnish platform is part of the standard service set that you will get in case you decide to host your sites in a semi-dedicated server
account. You can enable it for any of your websites via our innovative Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 megabytes, but if you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. As these two features aren’t tied to each other, you can use a few websites with the default amount of memory or you can get more memory in increments of 32 megabytes and use all of it for a single website. Varnish works best if you set a dedicated IP for the Internet sites that utilize its power. The Hepsia Control Panel will provide you with a simple way of rebooting any instance. Also, you’ll be able to delete the cached contents with just one single click.
Varnish in VPS Servers
You can take full advantage of the load balancing capabilities of Varnish with each of our VPS servers
in case you select Hepsia as your Control Panel. The Varnish content caching platform is offered by default and the amount of memory that it will be able to utilize to cache the content of your sites depends on the particular package that you have chosen, but even with the lower-end packages, you’ll have no less than several hundred megabytes of system memory at your disposal exclusively for caching purposes. This amount is sufficient enough to improve the overall performance of numerous Internet sites. It will take a little time for you to notice the effects, as Varnish caches the content that site visitors request, but shortly after that you’ll notice the substantially decreased load on your virtual machine and the increased website browsing speed. The Varnish platform will permit you to use a less powerful plan for sites which would typically require a more costly hosting solution.
Varnish in Dedicated Servers
When you need the most powerful web hosting solution and you acquire one of the dedicated servers
that we’re offering, you’ll be able to use the Varnish caching platform to improve the work of your Internet sites at no additional fee on the condition that the dedicated machine is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-work-with graphical interface will permit you to monitor system processes, to delete the cached contents or to reboot any instance with one single click. The minimal amount of memory that the caching platform can employ to cache website content is 3 gigabytes, which is quite enough for a vast number of high-demand Internet sites, so your server will be able to cope with a gigantic system load while your visitors are enjoying a seamless browsing experience. As your dedicated server will include several dedicated IP addresses, you’ll be able to use Varnish’s maximum capacity.
