Juju (formerly known as Ubuntu Ensemble) is an open source single service orchestration tool that works on public clouds, private clouds and the micro-clouds on Ubuntu developer workstations. The tool is developed by Canonical Ltd. It provides easy, intelligent service orchestration on top of environments such as OpenStack, Amazon AWS, or bare metal.

Through the use of charms, Juju provides users with an automated service deployment tool, making it possible to deploy cloud features in literally minutes.

With this software, developers and administrators can generate a pre-configured node of any type of cloud-based service according to best practices. You can use charms unmodified, or easily change and connect them to fit your needs.

The project initially had a slow start, but is now a leading cloud management tool.
