What Do Developers

Want?


For Developers...

• Self Service Operations

• The infrastructure is the application (and vice versa)

• Minimize Bottlenecks

• The “Right” Tools



What Does Operations Want?


Operations• Say “Yes”.

• You never liked rack and stack that much anyway.

• You have never been more critical.

• Just get out of the way.
