TurnKey Linux has launched a private beta of the TurnKey Hub, a service that makes it easy to launch and manage the open source project's Ubuntu-based virtual appliances in the Amazon EC2 cloud.

According to the developers, support for additional cloud platforms, as well as automatic backup and migration functionality is in the works.

"Imagine being able to develop your site on a locally running appliance (e.g., running in VirtualBox or VMWare). Then, when you're ready you can automatically migrate your appliance, with all your customizations to a cloud hosting provider of your choice."
