Varnish is a web app accelerator, which has been gaining a lot in popularity lately, because it can increase the speed of any site, at times even by 100%, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical machine and to improve the browsing speed for the website visitors. Each time a visitor accesses a page on a particular website, the web browser request is taken care of by the web server and the requested information is returned as a reply. 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 delivered by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator handles the web requests considerably quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is modified meanwhile, the cached webpages will also be updated the next time someone tries to open them.

Varnish in Cloud Web Hosting

You can unleash Varnish’s potential and optimize the speed of your sites regardless of the cloud web hosting plan that you have picked and you can add and configure the platform with a couple of clicks using the user-friendly GUI offered by our innovative Hepsia Control Panel. During the procedure, you will be able to choose two different things – how many Internet sites will use the Varnish caching platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can use more instances with less memory and vice versa. In case you’ve got plenty of content on a given site and you get lots of website visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will offer you simple one-click controls for discontinuing or restarting any instance, for erasing the cache associated with any site and for seeing comprehensive system logs.
