Learn precisely what Varnish is. Know much more about web accelerators and their role.
Varnish is a web accelerator, which has been gaining a lot in popularity lately, as it can increase the speed of any Internet 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 reduce the overall load on the physical server and to accelerate the browsing speed for the site visitors. Anytime a visitor accesses a page on a particular website, the web browser request is taken care of by the web server and the requested data is sent as a reply. If Varnish is enabled, it caches the pages that the website visitor browses and in case any of them is opened for a second time, it’s served by Varnish and not by the web server directly. The performance boost is due to the fact that the accelerator processes the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is modified in the meantime, the cached pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Cloud Website Hosting
Varnish is available as an optional upgrade with each of our Linux cloud website hosting packages
. You can add it to your hosting account via the Hepsia Control Panel, which comes with all shared hosting plans and you’ll get a rather simple-to-use interface, which will grant you full control over the data caching platform. Using one-click fast-access buttons, you can reboot or deactivate any of the instances, i.e. Varnish will no longer be enabled for a given site. You can also see an exhaustive system log or erase the cache for any of the websites. When you add Varnish to your web hosting package, you’ll be able to choose the total amount of system memory that will be at your disposal for data caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimum performance, you can set a dedicated IP for the sites that will use Varnish. This will permit you to get the most out of your Internet sites and to have numerous satisfied site visitors.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated packages
come with Varnish by default, so you can use the website accelerator tool and improve the load speed of any site that you host on our platform. You will get 64 MB of system memory exclusively for Varnish at no extra fee and you’ll be able to create an instance with no more than a few clicks through the Hepsia Control Panel, which is included with the semi-dedicated packages. In case you want more memory, the latter is available in increments of 32 megabytes through the Control Panel’s Upgrades section and it will be at your disposal instantaneously. You can also add more instances as a separate upgrade, so you can choose if a lot of data will be cached for one site or whether the memory will be used by different Internet sites. Hepsia will permit you to restart or to deactivate any instance, to see the system log for it or to delete the cached content using 1-click buttons. To take full advantage of Varnish, you can set a dedicated IP for the sites that will employ it.
Varnish in Dedicated Servers Hosting
If you need a more powerful web hosting solution and you order one of the Linux dedicated servers hosting packages
that we offer, you’ll be able to use the Varnish platform to enhance the work of your sites at no additional charge as long as the dedicated machine is ordered with our cutting-edge Hepsia Control Panel. Its simple-to-navigate GUI will allow you to keep an eye on system processes, to delete the cache or to reboot any instance with one single mouse click. The smallest amount of system memory that Varnish can use to cache site content is 3 GB, which is more than enough for a huge selection of resource-consuming Internet sites, so your server will be able to deal with a massive load while your Internet site visitors are having a seamless browsing experience. Since your server will include a number of dedicated IPs, you will be able to use Varnish’s full potential.
