Varnish is a web accelerator platform, which caches data for quicker access. It is occasionally called a caching HTTP reverse proxy as well and it works between a web server and a browser. When a website visitor opens a specific webpage, the content is requested by the web browser, and then the web server processes this request and delivers the needed data. If Varnish is activated for a site, it will cache its pages on the first visit and if the user visits a cached page once again, the information will be delivered by the caching platform and not by the server. The increased speed is an end result of the significantly faster response time that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the visitors will continue being served the exact same content again and again, since any update on any of the web pages is reflected in the content that Varnish keeps in its memory.
Varnish in Cloud Hosting
Varnish is offered as an optional upgrade with each of our Linux cloud hosting. You can add it to your account from the Hepsia hosting Control Panel, which is available with all shared packages and you will get an amazingly intuitive GUI, which will grant you complete control over the content caching platform. Using 1-click quick-access controls, you can reboot or shut down any of the instances, i.e. Varnish will no longer be enabled for a certain website. You can also check an exhaustive system log or delete the cache for any of the websites. When you add Varnish to your web hosting package, you will be able to select the total amount of system memory that will be available to you for caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for optimal performance, you can set a dedicated IP address for the sites that will use Varnish. This will permit you to get the most out of your Internet sites and to have plenty of happy visitors.
