JAAS is an enterprise layer on top of [Juju](https://canonical-juju.readthedocs-hosted.com/en/latest/).

JAAS provides:

- The Juju Infinite Model Manager, JIMM (and its [backing charm](https://charmhub.io/juju-jimm-k8s)):  A Juju enterprise-level controller.

- JIMM-specific extensions to existing Juju machinery, including

  * the [Juju CLI](https://canonical-juju.readthedocs-hosted.com/en/latest/user/reference/juju-cli/) (enhanced with `jimmctl`, for JIMM admins, and `jaas`, for regular JIMM users),

  * the [Juju dashboard](https://canonical-juju.readthedocs-hosted.com/en/latest/user/reference/juju-dashboard/) (and its [backing charm](https://charmhub.io/juju-dashboard), and

  * the [Terraform Provider for Juju](https://canonical-terraform-provider-juju.readthedocs-hosted.com/en/latest/).

When you use an existing Juju on Kubernetes controller to deploy JIMM and its dependencies, and then connect your Juju controllers to JIMM, you gain the ability to:

- use OIDC authentication for integration with your existing identity provider for federated login, service accounts and other features offered by identity providers;
- use ReBAC for authorisation;
- use the Juju CLI, Juju Dashboard, and the Terraform Provider for Juju to interact with multiple Juju controllers from a single point of contact.

If you are a site reliability engineer looking to take Juju to the enterprise level, you need JAAS.
