Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any Internet site, sometimes even by 100 percent, based on the content. This tool is occasionally referred to as an HTTP reverse proxy too and is used to reduce the overall load on the server and to increase the browsing speed for the website visitors. Whenever a visitor accesses a page on a particular website, the browser request is taken care of by the web server and the requested info is returned as a reply. If the Varnish accelerator is activated, it caches the web pages that the site visitor browses and if any of them is opened for a second time, it’s delivered by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any content is changed meanwhile, the cached web pages will also be updated the next time somebody accesses them.
Varnish in Web Hosting
If you host your sites in a web hosting account with our company, you’ll be able to activate Varnish with a few clicks through your hosting Control Panel. The data caching platform comes as an optional upgrade with all our web hosting packages and you can choose how many sites will use it and the total amount of system memory that will be used for the cached data. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they’re not directly tied to each other, so you can decide if you want plenty of memory for a single large-sized site or less memory for several smaller ones. You can use the full potential of Varnish if the websites use a dedicated IP address. With the Control Panel, you can swiftly start/restart/shut down an instance, clear the cached contents individually for each site which uses the Varnish platform or check an exhaustive log file.
Varnish in Semi-dedicated Hosting
Varnish is included in the default set of services that you will acquire if you choose to host your sites under a semi-dedicated server account. You can activate it for any of your websites via our leading-edge Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the Internet sites that can use this platform at the same time. As these two features are not linked to each other, you can use a couple of instances with the default memory or you can add more memory in increments of 32 MB and use all of it for a single site. The Varnish platform performs best when you use a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you a simple way of restarting any instance. Furthermore, you will be able to delete the cached files with only one click of the mouse.
Varnish in VPS
You can take full advantage of the load balancing potential of Varnish with any of our VPS packages when you pick Hepsia as your web hosting Control Panel. The platform is offered by default and the memory that it will be able to use to cache your website content depends on the given Virtual Private Server plan that you’ve selected, but even with the lower-end packages, you’ll have at least several hundred MB of system memory at your disposal exclusively for content caching purposes. This amount is sufficient to enhance the work of multiple sites. It’ll take a little time for you to detect the effects, since the Varnish platform caches the content that site visitors browse, but soon after that you will notice the significantly reduced load on the machine and the accelerated website browsing speed. The Varnish caching platform will allow you to make use of a lower-end VPS plan for sites which would usually require a more pricey hosting service.
Varnish in Dedicated Hosting
When you need a powerful hosting solution and you purchase any of the dedicated servers hosting packages offered by us, you will be able to use the Varnish data caching platform to boost the overall performance of your websites at no additional fee as long as the server is ordered with our next-generation Hepsia Control Panel. Its simple-to-navigate graphical interface will enable you to keep track of system processes, to clear the cached files or to restart any instance with a click. The smallest amount of system memory that the Varnish caching platform can employ to cache Internet site content is 3 GB, which is quite enough for a large collection of resource-hungry Internet sites, so your dedicated server will be able to cope with a substantial load while your site visitors are having a smooth browsing experience. As your dedicated server will come with several different dedicated IP addresses, you’ll be able to use Varnish’s maximum capacity.
