Juju

Juju is an enterprise Operator Lifecycle Manager (OLM) that provides model-driven application management and next-generation infrastructure-as-code.

The Kubernetes operator pattern replaces configuration file management with software-defined operations and shared, reusable ops code packages. Juju expands this idea to include traditional apps on Windows and Linux.

As a universal operator lifecycle manager for containers, virtual machines and bare metal that manages provisioning and underlying infrastructure, Juju provides a clean approach to multi-cloud operations. Applications can be managed on multiple clouds, and on premise, in machines or on Kubernetes, and then integrated automatically.

Operators are packaged in charms and distributed through Charmhub.io which hosts the Open Operator Collection. A charm is a compressed archive of the operator code and metadata, which can also be shared directly along with applications.
