Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, as it can increase the speed of any Internet site, sometimes even by 100 percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to lower the overall server load and to boost the access speed for the site visitors. Every time a visitor opens a page on a particular site, the browser request is taken care of by the web server and the requested info is returned as a reply. If Varnish is enabled, it caches the web pages that the visitor opens and in case any of them is loaded once again, it’s delivered by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator handles the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any content is modified meanwhile, the cached webpages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each of our cloud hosting plans. You can add it to your hosting account via the Hepsia hosting Control Panel, which is offered with all shared hosting packages and you’ll get a truly intuitive GUI, which will grant you full control over the caching platform. Using 1-click quick-access buttons, you can restart or discontinue any of the instances, i.e. Varnish will no longer be activated for a given Internet site. You can also check an elaborate system log file or erase the cache associated with any of the websites. When you add Varnish to your hosting package, you’ll be able to choose the maximum amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 MB and, for optimal performance, you can get a dedicated IP address for the sites that will use Varnish. This will permit you to take full advantage of your websites and to have many pleased website users.
