MAAS/Juju architecture and issues
- by Massimo
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 reliable, i.e. deployed over two or more physical nodes able to fail-over ?
2) can the same physical cluster host multiple juju environments, under the assumption 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 ?
