Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, sometimes even by 100%, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical server and to improve the access speed for the website visitors. Each time a visitor loads a page on a certain site, the web browser request is handled by the web server and the requested content is returned as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and in case any of them is loaded once again, it’s served by Varnish and not by the web server directly. The performance increase is due to the fact that the accelerator processes the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. In case any data is modified meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Cloud Hosting

Varnish comes as an optional upgrade with each of our cloud plans. You can add it to your web hosting account via the Hepsia hosting Control Panel, which comes with all shared packages and you’ll get an amazingly user-friendly graphical interface, which will grant you full control over the data caching platform. Using 1-click fast-access controls, you can restart or terminate any of the instances, in other words – Varnish will no longer be activated for a certain site. You can also check a comprehensive log or clear the cache for any of the sites. When you add Varnish to your web hosting package, you’ll be able to select the total amount of memory that will be at your disposal 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 assign a dedicated IP address to the sites that will use Varnish. This will enable you to get the most out of your sites and to have plenty of satisfied website visitors.
