Juju is a Charmed Operator Framework, composed of a Charmed Operator Lifecycle Manager and the Charmed Operator SDK.
Juju is an Open Source Charmed Operator Framework. It helps you move from configuration management to application management and has two main components:
Charmed Operator Lifecycle Manager (OLM) - a hybrid-cloud application management and orchestration system that helps you from Day 0 to Day 2. Deploy, configure, scale, integrate, maintain and manage Kubernetes native, container-native and VM-native applications -- and the relations between them.
Charmed Operators, packaged as “Charms”, are software that encapsulate a single application and all the code and know-how it takes to operate it on Kubernetes or machines.
Charmed Operator SDK - a guide to help you build Charmed Operators for use with the Charmed OLM.
