Varnish is a web accelerator, which has been gaining a lot of popularity lately, as it can increase the loading speed of any website, sometimes even by one hundred percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall load on the physical machine and to improve the access speed for the website visitors. Each time a visitor accesses a page on a specific Internet site, the web browser request is processed by the web server and the requested content is delivered as a reply. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and if any of them is opened once again, it is served by Varnish and not by the server directly. The boost in the overall performance is due to the fact that the accelerator handles the web requests substantially faster than any web server, which results in much faster browsing speeds for the users. If any data is changed in the meantime, the cached web pages will also be ‘refreshed’ the next time somebody attempts to access them.

Varnish in Cloud Web Hosting

You can make use of Varnish’s full potential and improve your sites’ loading speed irrespective of the cloud web hosting package that you’ve picked and you can enable and configure the data caching platform with a couple of clicks via the user-friendly graphical interface offered by our next-gen Hepsia Control Panel. During the process, you will be able to choose two separate things – how many websites will use Varnish, i.e. the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and the other way around. In case you’ve got lots of content on a specific website and you draw numerous website visitors, more system memory will guarantee you better results. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will provide you with easy one-click controls for stopping or restarting any instance, for erasing the cache for any website and for checking exhaustive system logs.
