CMDB:
    I do not have names on specific commentors. These notes have been re-ordered to make a bit more sense.

We have dynamic environments, with information coming from systems and builds.
Systems need configuration from runtime data based on service discovery and build configuration (IP addresses, versions, etc).

CMDB use contexts:
    On call users - The sysadmin who has been paged at 4 am needs to determine context for the page.
    Deployment systems - To know where to deploy software, what version(s) to deploy, etc.
    Maintenance - Downtimes, escalate, software versions, hardware info...
