7. SDP strategy
• Most of us building something like SDP
• With typical continuous improvement
budget, this can take years in established
companies :(
• Large jumpstart efforts getting funded in
some firms - otherwise use MVP

8. Quick Syntax
Utilization Survey

9. Syntax Proficiency
Survey
• Literally - “well advanced in an art,
occupation, or branch of knowledge”
• Lee’s definition - ability to understand, test,
correct and release someone else’s code

10. SystemicViewpoint
• Does your org understand convergence,
imperative vs declarative, topographic sort,
etc.
• If not, do you have the budget and foresight
to train....
• If not?

16. or another wall?
• A complex DevOps solution understood
only by an underfunded skeleton crew can
make the DevOps problem worse
Sunday, May 4, 14

17. Architects and
Complexity
• Good architecture should remove
complexity
• Doesn’t always happen that way
Sunday, May 4, 14

18. Bash
• Everyone knows it
• Not Object Oriented
• Typically untested
• Typically poor modularity

19. Rerun

20. Compatible!
• Puppet
• Chef
• Rundeck
• Ansible
• Salt Stack
• And many more!
Sunday, May 4, 14

21. Powershell
• Rundeck and Powershell very similar tab
browsability on the command line
• Lots of DevOps project on Windows!
• Modules very similar
• Powershell is verb/noun. I typically do
noun/verb, but whatever...
• Would like to see unit test semantics in
Powershell.

22. To the break...
• Nothing wrong with well tested imperative
code, convergence does scale better
though
• Upside is better participation across
organizational boundaries
• Easy to switch between Linux/Windows
• People are part of the solution
• MVP
