Varnish is a web app accelerator tool, which has been gaining a lot in popularity lately, because it can increase the speed of any site, at times even by 100 percent, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy too and is used to reduce the overall server load and to accelerate the browsing speed for the website visitors. Whenever a visitor accesses a page on a certain Internet site, the browser request is processed by the web server and the requested info is delivered as a response. If Varnish is enabled, it caches the web pages that the visitor opens and if any of them is opened once more, it is served by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator processes the web requests tremendously quicker than any web server, which results in much faster browsing speeds for the users. If any data is updated in the meantime, the cached webpages will also be updated the next time somebody tries to access them.
Varnish in Cloud Web Hosting
Varnish is offered as an optional upgrade with each and every Linux cloud web hosting package and if you wish 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 things that can be upgraded – the number of instances and the memory. The first one pertains to the number of the sites that you wish to employ Varnish for, whereas the second, which is available in increments of 32 MB, refers to the maximum amount of data that the platform can cache at any given time. The Hepsia Control Panel’s easy-to-work-with graphical interface will permit you to deactivate or to restart any instance, to see comprehensive logs or to erase the platform’s cache with just a click. For optimal results, you can employ a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your website will load tremendously faster, which means more happy visitors and potential clients.
