Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I recently deployed a MAAS/Juju environment based on a six nodes cluster, using Ubuntu 12.04 LTS, to run a "proof of concept". I could appreciate how interesting the architecture is, and I'd like to understand if I can really base my future business on this technology. Therefore I'd like to understand more about any involved limitations, constraints and necessities.

In particular I'd like to understand:

  1. How can MAAS be made High Availability, I.E. deployed over two or more physical nodes able to fail-over ?
  2. Can the same physical cluster host multiple Juju environments, assuming openstack/virtualization is not used ?
  3. Can the same physical node host different charms of the same Juju environment, deployed in a standard, reliable way by Juju?
