7. Configuration Management
I hope this works, it’s my first second third.

8. My Philosophy
• Provide stable, secure, consistent servers
• Dev/Apps and Ops are symbiotic
• Provide documentation
• Provide Dev/Apps everything they need to
do *their* job

9. Our current state:
Cats.
• They do what they want.
• They answer to no-one.
• They go where they want.
• I don’t like cats.

11. Why Dogs?
They can be trained to do anything.
