I've been reading: https://help.ubuntu.com/community/UbuntuCloudInfrastructure

It's fascinating stuff, but documentation seems a bit sparse. Where I work, we have this aging, clunky VMWare ESXi setup for all our internal servers. I'd really like to read up on possible migration or just information on Orchestra, integration with Juju, etc that isn't a bunch of loosely connected blog posts. :p

This is concerning 11.10 and, presumably, 12.04.

To make this less vague, specifically documentation on:

• Orchestra - features, comparisons, videos, etc
• Integrating Juju with Orchestra - I'm familiar with using Juju for deploying on AWS, but that wiki page glances over connecting it to orchestra
• Building a private cloud - Advantages, using/deploying Openstack, etc
• Working with internal networks - Configuring DMZs, setting rules, etc

Any recommended books would be appreciated too. I didn't intend for this to be a 'do all my homework for me! LMGTFY' post, I'm just hungry for information and haven't found a good repository of knowledge for much of this.
