Varnish is a web accelerator, which has been gaining a lot of popularity lately, because it can increase the loading speed of any website, sometimes even by 100%, based on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the server and to improve the browsing speed for the site visitors. Anytime a visitor opens a page on a particular site, the web browser request is taken care of by the web server and the requested information is served as a reply. If Varnish is enabled, it caches the pages that the site visitor opens and if any of them is accessed for a second time, it is served by Varnish and not by the server directly. The boost in the overall performance comes from the fact that the accelerator handles the web requests tremendously faster than any web server, which results in much faster browsing speeds for the visitors. In case any data is updated in the meantime, the cached pages will also be ‘refreshed’ the next time somebody opens them.
Varnish in Cloud Hosting
You can unleash Varnish’s potential and boost the speed of your sites irrespective of the cloud hosting package that you’ve selected and you can activate and configure the data caching platform with a few clicks through the simple-to-use interface offered by our avant-garde Hepsia hosting Control Panel. During the procedure, you’ll be able to select two separate things – how many Internet sites will use the Varnish caching platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of system 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 the other way around. If you’ve got lots of content on a given Internet site and you draw numerous site visitors, more system memory will give you better results. You may also consider employing a dedicated IP for the Internet sites that will use the Varnish caching platform. Hepsia will offer you easy one-click controls for terminating or restarting any instance, for deleting the cache for any website and for viewing in-depth system logs.
