Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any site, sometimes even by 100 percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to accelerate the browsing speed for the site visitors. Anytime a visitor opens a page on a particular website, the web browser request is handled by the web server and the requested data is returned as a reply. If Varnish is enabled, it caches the web pages that the site visitor opens and in case any of them is opened for a second time, it’s delivered by Varnish and not by the server directly. The improvement in the overall performance is due to the fact that the accelerator processes the web requests substantially faster than any web server, which results in much faster browsing speeds for the users. In case any content is updated meanwhile, the cached webpages will also be updated the next time somebody tries to access them.
Varnish in Cloud Hosting
Varnish is available as an optional upgrade with each cloud hosting and if you’d like to use it, you can add it to your shared account using the Upgrades section in your Hepsia hosting Control Panel. There’re two separate features that can be upgraded – the number of instances and the memory. The first one pertains to the number of the sites that you’d like to use Varnish for, whereas the second, which is available in increments of 32 megabytes, shows the total amount of data that the platform can cache at any particular moment. Hepsia’s easy-to-work-with graphical interface will permit you to discontinue or to restart any instance, to see comprehensive system logs or to erase the platform’s cache with just a click. For optimum results, you can employ a dedicated IP for the sites that will use the caching platform. With Varnish, your Internet site will load much faster, meaning more satisfied site visitors and prospective clients.
