Varnish is a web accelerator, which has been gaining a lot of popularity lately, because it can increase the loading speed of any site, sometimes even by 100%, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the physical server and to improve the browsing speed for the site visitors. Every time a visitor loads a page on a particular Internet site, the web browser request is taken care of by the web server and the requested content is served as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and in case any of them is loaded once again, it is served by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which leads to much faster browsing speeds for the visitors. If any content is updated in the meantime, the cached web pages will also be updated the next time somebody tries to open them.
Varnish in Web Hosting
Varnish is available as an optional upgrade with all our Linux web hosting packages
. You can add it to your web hosting account via the Hepsia Control Panel, which is available with all shared hosting packages and you’ll get an amazingly simple-to-use interface, which will grant you full control over the caching platform. Using one-click quick-access controls, you can restart or remove any of the instances, in other words – Varnish will no longer work for a particular Internet site. You can also view a comprehensive log file or erase the cache associated with any of the websites. When you add Varnish to your shared hosting package, you’ll be able to choose the total amount of memory that will be at your disposal for caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will allow you to get the most out of your Internet sites and to have plenty of happy users.
Varnish in Semi-dedicated Hosting
The Varnish data caching platform is included in the basic set of services that you’ll receive if you choose to host your websites under a semi-dedicated server
account. You can activate it for any of your sites through our innovative Hepsia Control Panel. The default memory that the Varnish caching platform can use to cache content is 64 MB, but if you decide that you need 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 sites that can use this caching platform simultaneously. Since these two features are not bound to each other, you can use a couple of sites with the default memory or you can order more memory in increments of 32 MB and use all of it for one single web site. Varnish performs best if you set a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with an easy way of rebooting any instance. In addition, you will be able to clear the cached content with only one mouse click.
Varnish in Dedicated Hosting
All Linux dedicated servers hosting packages
that are ordered with the tailor-made Hepsia hosting Control Panel include Varnish, which is one of the pre-installed software platforms that you’ll get with the machine. The Varnish platform can be activated and administered without effort from Hepsia’s time and effort saving graphical interface and, with no more than one single mouse click, you can see an in-depth log, create or restart an instance, delete the cache associated with any site and much more. Soon after you enable the Varnish platform for a particular domain or sub-domain, it will start caching the pages loaded by your website visitors and once it has cached enough content, you’ll observe a considerably better site performance plus a lowered load on the dedicated server. With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the platform for workload distribution purposes even if you host many Internet sites on your machine.
