#10: Separate environments

Separate production and development networks
Don't let developers access production systems
- Unless there is an emergency...and then only briefly to diagnose a problem
Keep QA off of production hardware, too
Production hardware is for production only!
You'll never achieve resiliency without separate environments
- Change control cannot be enforced

You may need six environments:
1. Production: Everything works and doesn't change
2. Production mirror: If a prod change goes badly
3. Disaster recovery: Survive after catastrophe hits
4. QA: Change is controlled and tested
5. Development: Works in progress
6. Lab: Playground; preliminary test bed for new hardware and third party software

Could combine prod mirror and disaster recovery
- Definitely better not to, though...
