Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any website, at times even by one hundred percent, based on the content itself. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall server load and to improve the browsing speed for the site visitors. Anytime a visitor opens a page on a given site, the browser request is handled by the web server and the requested content is delivered as a reply. If the Varnish accelerator is activated, it caches the pages that the site visitor opens and if any of them is loaded again, it’s fetched by Varnish and not by the server directly. The boost in the overall performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is updated meanwhile, the cached pages will also be updated the next time somebody opens them.
Varnish in Cloud Website Hosting
If you host your Internet sites in a cloud website hosting account with our company, you’ll be able to add Varnish with several clicks of the mouse from your Control Panel. The content caching platform is offered as an upgrade with all our plans and you can choose how many sites will use it and the maximum storage space that will be used for the cached content. The two features that can be upgraded in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t directly tied to each other, so you can decide whether you want lots of memory for one large-sized site or less memory for several smaller ones. You can unleash the full potential of Varnish if the sites use a dedicated IP address. Using the Control Panel, you can effortlessly start/reboot/disable an instance, clear the cached content independently for each website that employs Varnish or check an exhaustive system log.
