5. Clean room environment Safe by default Installs dependences Built in a studio
6. Central location Publicly hosted Lightweight views Stored in a depot
7. Easy pattern Shortcuts Increasing specificity Installed by hab
8. Binaries and Config Metadata Side-by-side Packages on disk
9. Docker ACI Mesosphere Post-process packages

12. Print config options 12-Factor style Externally enforced Environment configuration
13. More flexible than environment Universal location Externally enforced File configuration
14. Supervisors form a ring Peers Service Groups Gossip Availability increases with scale
15. Supervisors support topologies Dynamic configuration Service group level Uses the ring
16. Supervisors provide update strategies Topology aware Tracks views in the depot Ideal for Continuous Delivery
17. Supervisors provide a REST API External Actors Health and Status Supervisor Debugging
18. Automation travels with the application Existing & Cloud Native Software Application Automation
