Did not get to the items in blue below.

Review AIs - DONE
Discuss and finalize Guiding Principles
- #9 Stateless microservices
  - stateless = state not held in the code
- #5 non-disruptive upgrades
  - is this referring to the services or the managed systems or both? Clarify this: AI
- #3A secure external interfaces
  - was read as the security was "optional". Clarify AI
Proposed near term discussion topics
- Footprint reduction
  - With an expectation of maintained performance
  - There is a relationship to scaling
  - A footprint relative to scale
- Unified Data Model
  - RackHD native (based on IPMI and microkernel catalog)
  - Advance PE Service (based on WS-MAN catalog)
  - Voyager
    - graph-based topology database
  - Grooming - Update based on changes, removal of stale information
