Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any Internet site, sometimes even by one hundred percent, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to increase the access speed for the site visitors. Every time a visitor loads a page on a specific website, the browser request is processed by the web server and the requested data is returned as a response. If Varnish is activated, it caches the web pages that the site visitor opens and in case any of them is opened again, it is delivered by Varnish and not by the server directly. The performance increase is due to the fact that the accelerator handles the browser requests tremendously faster than any web server, which results in much faster browsing speeds for the site visitors. In case any data is modified in the meantime, the cached webpages will also be ‘refreshed’ the next time someone tries to open them.
Varnish in Cloud Hosting
Varnish comes as an optional upgrade with each Linux cloud hosting and if you would like to use it, you can add it to your hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There’re two different features that can be upgraded – the number of instances and the memory. The first one depends on the number of the websites that you would like to use Varnish for, whereas the second, which is offered in increments of 32 megabytes, shows the total amount of content that the content caching platform can store at any particular moment. Hepsia’s easy-to-use graphical interface will permit you to shut down or to restart any instance, to view exhaustive logs or to clear the platform’s cache with just one mouse click. For optimum results, you can employ a dedicated IP address for the Internet sites that will use the platform. With Varnish, your site will open substantially faster, which means more satisfied visitors and prospective clients.
