Juju (software)

Juju aims to provide a modeling language that abstracts the specifics of operating complex software topologies to reduce the cost of operations and provide flexibility. A Juju model is an environment to manage and operate a set of software applications. Models can be operated on a variety of public clouds. A Juju controller is a service that tracks the events, state, and user activity across multiple models. A database server tool and databases available on a server are an example of a Juju controller and its models. Each model can have different configurations, sets of operating software, and users with various levels of access. Examples of models include a web application, load balancer, and database in a "web-app" model. Models allow deployments to be isolated into logical solutions and managed separately.
