Varnish is a web application accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, sometimes even by 100 percent, based on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall load on the physical server and to increase the browsing speed for the site visitors. Whenever a visitor opens a page on a certain Internet site, the web browser request is handled by the web server and the requested content is returned as a response. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and if any of them is opened once again, it’s delivered by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator handles the browser requests significantly faster than any web server, which results in much faster browsing speeds for the users. If any data is changed in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Cloud Hosting
If you host your websites under a cloud hosting account with our company, you will be able to add Varnish with a few clicks of the mouse through your Control Panel. The data caching platform is available as an optional upgrade with all our shared web hosting plans and you can choose how many websites will use it and the total storage space that will be available for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they aren’t directly tied to each other, so you can choose if you need lots of memory for one single large-size website or less memory for several smaller ones. You can unlock the full potential of the Varnish platform if the websites use a dedicated IP. Using the hosting Control Panel, you can quickly start/reboot/stop an instance, delete the cached contents individually for each site that uses the Varnish platform or see an in-depth log file.
