[[wp:Juju (software)|Juju]] (formerly Ensemble) is an open source service orchestration management tool developed by Canonical Ltd., the company behind [[Ubuntu]]. Juju allows software to be quickly deployed, integrated and scaled on a wide choice of cloud services or servers.
Juju can deploy to LXC <ref>See also: [[Docker]]</ref> (for local environments), OpenStack (for HP Cloud), Windows Azure, Joyent or Amazon EC2 Kapil Thangavelu wrote [https://github.com/kapilt/juju-digitalocean JuDo] - A juju provider for digital ocean using a client side plugin and manual provisioning.
