Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any site, at times even by one hundred percent, based on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to enhance the browsing speed for the site visitors. Every time a visitor opens a page on a particular Internet site, the browser request is processed by the web server and the requested data is returned as a response. If the Varnish accelerator is activated, it caches the web pages that the site visitor opens and in case any of them is loaded once again, it is served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the site visitors. If any content is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with each cloud plan and if you want to use it, you can add it to your shared website hosting account via the Upgrades menu in your Hepsia Control Panel. There are two separate features that can be upgraded – the number of instances and the system memory. The first one refers to the number of the websites that you wish to employ Varnish for, whereas the second, which comes in increments of 32 megabytes, refers to the maximum amount of content that the content caching platform can cache at any particular moment. The Hepsia Control Panel’s easy-to-use GUI will enable you to cancel or to restart any instance, to view detailed logs or to clear the platform’s cache with just one click. For maximum results, you can use a dedicated IP for the websites that will use the platform. With Varnish, your website will open considerably faster, which means more satisfied visitors and prospective clients.
