Open Stack

Worth noting the cloud's 'Cambrian explosion' we are experiencing for the
"AppDev Toolbox" at the moment.

For example, just saw an options paper for K8S atop OpenStack, where there
are several pages of options.
^^ See Kubernetes slack/irc channel #OpenStack-SIG (I'll send the link anon
currently in transit).

Best, Flanders
