Juju is an "automatic service orchestration" project launched by Canonical, developers of the Ubuntu Linux-based operating system, to deploy, manage and scale software and interconnected services across one or more Ubuntu servers and cloud platforms.
Juju is designed to work with Canonical's metal-as-a-service (MAAS) to help streamline the process of deploying and managing resources and services in hyperscale computing environments such as big data workloads and cloud services.
Initially developed under the name "Ensemble," Juju takes its new moniker from an African word for "magic." Following in that theme, Juju utilizes "charms," which are open source tools that simplify specific deployment and management tasks. Juju charms can be written in any executable language.
