Varnish is a web app 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%, based on the content itself. This tool is sometimes called an HTTP reverse proxy as well and is used to reduce the overall load on the server and to improve the browsing speed for the website visitors. Every time a visitor loads a page on a given Internet site, the browser request is handled by the web server and the requested content is served as a response. If the Varnish accelerator is enabled, it caches the web pages that the site visitor opens and in case any of them is loaded for a second time, it’s served by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time someone tries to access them.

Varnish in Website Hosting

If you host your websites in a website hosting account with us, you’ll be able to add Varnish with several mouse clicks through your Control Panel. The platform is offered as an upgrade with all our web hosting plans and you can select the number of the sites that will use it and the total storage space that will be available for the cached content. The two upgradeable features in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t linked directly to each other, so you can decide whether you need a lot of memory for one single large-scale website or less memory for several smaller ones. You can unlock the full potential of Varnish if the sites use a dedicated IP. Using the hosting Control Panel, you can easily start/reboot/stop an instance, delete the cached files individually for each website which uses Varnish or see a comprehensive system log.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the standard service set that you’ll receive when you choose to host your websites in a semi-dedicated server account. You can activate it for any of your websites via our avant-garde Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you need more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform simultaneously. Since these two features are not tied to each other, you can use a few Internet sites with the default memory or you can get more memory in increments of 32 megabytes and use all of it for a single site. The Varnish platform performs best when you set a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will give you a simple means of rebooting any instance. In addition, you’ll be able to clear the cached contents with just a click.

Varnish in Dedicated Servers

If you need a powerful web hosting solution and you buy any of the dedicated web hosting plans that we offer, you can use the Varnish caching platform to optimize the overall performance of your sites at no extra charge on the condition that the server is ordered with our cutting-edge Hepsia Control Panel. Its easy-to-use graphical interface will enable you to monitor system processes, to clear the cached files or to restart any instance with a click. The smallest amount of system memory that the caching platform can employ to cache content is 3 GB, which is more than enough for an enormous number of regularly visited Internet sites, so your dedicated server will be able to handle a tremendous system load while your site visitors are having a smooth web browsing experience. As your machine will include several dedicated IPs, you will be able to make use of Varnish’s maximum capacity.
