Varnish is a website accelerator platform, which caches data for the sake of quicker response times. It’s sometimes referred to as an HTTP reverse proxy as well and it interacts between a web server and a browser. When a site visitor accesses a specific webpage, the content is requested by the web browser, and then the server handles this browser request and delivers the requested information. If Varnish is enabled for a site, it will cache the pages at the very first request and if the user visits a cached page again, the info will be delivered by the accelerator platform instead of the web server. The increased speed is a result of the much faster response time that the Varnish platform offers as compared with any server software. Of course, this does not mean that the users will continue being served the very same content over and over again, as any update on any of the pages is reflected in the content that Varnish caches in its memory.

Varnish in Cloud Web Hosting

In case you host your Internet sites under a cloud web hosting account with our company, you will be able to activate Varnish with a couple of clicks through your hosting Control Panel. The caching platform is available as an optional upgrade with all our hosting plans and you can select how many sites will use it and the total amount of system memory that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they are not directly linked to each other, so you can decide whether you need a lot of memory for one single large-scale website or less memory for several smaller ones. You can use the full potential of Varnish in case the sites use a dedicated IP. Using the hosting Control Panel, you can easily start/restart/delete an instance, delete the cached data individually for each website that uses the Varnish platform or check a detailed log file.
