Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any site, sometimes even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to reduce the overall server load and to improve the access speed for the site visitors. Whenever a visitor opens a page on a specific Internet site, the web browser request is handled by the web server and the requested data is sent as a response. If Varnish is activated, it caches the web pages that the website visitor opens and if any of them is loaded once more, it’s served by Varnish and not by the web server directly. The boost in the performance comes from the fact that the accelerator processes the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the website visitors. If any content is edited in the meantime, the cached web pages will also be updated the next time someone tries to open them.

Varnish in Cloud Web Hosting

Varnish comes as an optional upgrade with each of our cloud web hosting. You can add it to your web hosting account via the Hepsia hosting Control Panel, which is offered with all shared packages and you’ll get a rather easy-to-use GUI, which will grant you complete control over the data caching system. Using one-click fast-access buttons, you can restart or delete any of the instances, i.e. Varnish will no longer work for a certain Internet site. You can also view a detailed log file or delete the cache associated with any of the websites. When you add Varnish to your web hosting plan, you’ll be able to select the maximum amount of system memory that will be available to you for caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for best performance, you can assign a dedicated IP address to the sites that will use Varnish. This will enable you to take full advantage of your sites and to have a lot of satisfied users.
