Juju is an open source universal OLM that allows to deploy, configure, scale, and operate cloud infrastructures quickly and efficiently using operators (charms). Juju OLM is universal, meaning that it supports container substrates like Kubernetes as well as traditional machine substrates like MAAS, VMware, OpenStack, or public cloud infrastructure.
The Open Operator Collection allows access to a wide range of best practice solutions that can be deployed with a single command. Juju can be managed from the command line or through its powerful graphical representation of the model in the UI.
