Metal as a Service -- MAAS -- lets you treat physical servers like virtual machines in the cloud. Rather than having to manage each server individually, MAAS turns your bare metal into an elastic cloud-like resource.

What does that mean in practice? Tell MAAS about the machines you want it to manage and it will boot them, check the hardware's okay, and have them waiting for when you need them. You can then pull nodes up, tear them down and redeploy them at will; just as you can with virtual machines in the cloud.

When you're ready to deploy a service, MAAS gives your tool of choice (e.g. Ansible, Chef, Puppet, SALT, Juju) the nodes it needs to power that service. It's as simple as that: no need to manually provision, check and, afterwards, clean-up. As your needs change, you can easily scale services up or down. Need more power for your Hadoop cluster for a few hours? Simply tear down one of your Nova compute nodes and redeploy it to Hadoop. When you're done, it's just as easy to give the node back to Nova.

MAAS is ideal where you want the flexibility of the cloud, and the hassle-free power of Juju charms, but you need to deploy to bare metal.

pronouncebale machine names

I understand that sabdfl specifically requested 5-character machine names in MAAS (rather than MAC or IP based names like AWS).

I'd like to make an additional request from a usability perspective... Can we please make the MAAS machine names pronounceable? It's really, really difficult to talk about machines in a cluster when the name is "kslnw" or "xpxrqm".

Here's a suggestion:

$ sudo apt-get install wamerican
$ shuf -n 1 /usr/share/dict/american-english | sed 's/[^a-zA-Z]//g'

That gives much more readable, though still random, machine names. That dictionary has 100K words in it. There's also wbritish, wcanadian. See the scowl source package or http://wordlist.sourceforge.net/ for more information.
