 I agree it is time to add a new entry for a new date to our vision
document.

I also had an interesting conversation about also allowing NGS to be
invoked directly. We've sort of mused with the idea before, but I think
maybe someone hacking on it might be the next logical step.

Also, a number of different interests in use of DPUs, from "hiding" LACP
from the workload to wanting to do VXLAN or geneve tunnel termination.
Given I'm leading work to try and get us into a place to better support
things such as this, I expect it will be a topic we'll be revisiting in the
next few months.

Would a one shot command deploy thing be of value?

Consider this a solid +1!

I was *really* surprised by the number of conversations I had where someone
had a large BMaaS sort of cloud, and where they were presently using
Terraform to drive Nova to ask for nodes from ironic. Flavor sprawl was an
aspect that also came up because of a need for more or less matching down
to represent required physical architectures for multi-machine workloads. I
think it would be wise of us to try and push that capability forward so
operators could leverage terraform with a whole deployed cloud or an Ironic
only BMaaS cloud.

At the same time, I would encourage us to also think of other use
integrations and generally theme to make it easier to tie into processes
and tools where operators presently take multiple steps.
