580 Million Years Ago…
Environmental, developmental, and ecological changes accelerated the rate of evolution by

Cambrian Explosion
“A Period of Combinatorial Innovation”
Recall component parts that innovators could combine or recombine to create new inventions: In the 1800s, it was interchangeable parts. In 1920, it was electronics. In the 1970s, it was integrated circuits.
Hal Varian a Chief Economist for Google

Cambrian Explosion
Today(John Willis) argues we are at the base of an
explosion of innovation driven primarily by four factors:
• Abstract and fault tolerant components• Unlimited infrastructure• World wide collaboration• Changes in intellectual property

Cambrian Explosion
Abstract and Fault Tolerant Components
• Components are abstract• Bits, software, virtualized• Clustered• Fault tolerant• Parallelized

Cambrian Explosion
Unlimited Infrastructure
• You never run out of them• So there’s no shortage• There are no inventory delays• You can reproduce them• You can duplicate them, you can spread them
around the world

Cambrian Explosion
World Wide Collaboration
• You can have thousands and tens of thousands of innovators combining or recombining the same
component parts to create new innovation.• It’s a situation where the components are available
for everyone.

Cambrian Explosion
Changes in Intellectual Property
• Revolution in how we view intellectual property• Open source• Google – I can be an expert on anything in a matter
of minutes… worst case one day.

The rise of exceedingly dynamic businesses and infrastructures to support them created the need for DevOps....
But the sea change in tools, and methodologies that have resulted apply to far more than just those young upstarts startups whippersnappers!

What is Chef?
Chef is a data-driven systems integration platform
Chef runs infrastructure as a business application

Chef enables Infrastructure as Code
Manage configuration as idempotent Resources.Put them together in Recipes.
Track it like source code.Configure your servers.

Some Principles of Chef’s Design...
You specify the desired result and Chef takes action that will place the system in that state.
