Formerly called Ensemble, juju is DevOps DistilledTM. Through the use
of charms (renamed from formulas), juju provides you with shareable,
re-usable, and repeatable expressions of DevOps best practices. You
can use them unmodified, or easily change and connect them to fit your
needs. Deploying a charm is similar to installing a package on Ubuntu:
ask for it and it’s there, remove it and it’s completely gone.
In this talk, we will discuss the concepts behind juju, and run a live
demonstration of juju for deploying and managing various workloads on
an OpenStack cloud running on top of Ubuntu Server.
