Juju is a free and open-source application modeling tool developed by Canonical Ltd. Juju is an application management system. It was built to reduce the operation overhead of software by facilitating, deploying, configuring, scaling, integrating, and performing operational tasks on public and private cloud services along with bare-metal servers and local container-based deployments.
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.
