Varnish is a website accelerator, which has been gaining a lot in popularity in recent years, because it can increase the loading speed of any website, sometimes even by 100%, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the physical machine and to boost the access speed for the website visitors. Each time a visitor accesses a page on a specific website, the browser request is handled by the web server and the requested data is served as a reply. If Varnish is enabled, it caches the web pages that the site visitor browses and in case any of them is accessed once again, it is fetched by Varnish and not by the web server directly. The performance boost is due to the fact that the accelerator handles the browser requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. In case any data is changed in the meantime, the cached pages will also be ‘refreshed’ the next time somebody accesses them.

Varnish in Cloud Hosting

Varnish is available as an optional upgrade with all our cloud hosting plans. You can add it to your hosting account from the Hepsia hosting Control Panel, which is available with all shared plans and you will get a quite user-friendly graphical interface, which will give you full control over the data caching system. Using 1-click quick-access controls, you can reboot or remove any of the instances, in other words – Varnish will no longer be enabled for a certain website. You can also view an exhaustive system log or delete the cache associated with any of the Internet sites. When you add Varnish to your web hosting plan, you will be able to choose the total amount of memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for best performance, you can set a dedicated IP for the sites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have a lot of pleased visitors.
