What is the Cloud?
A pool of self-service infrastructure and middleware components which are available on-
demand in near real-time; effectively making IT Infrastructure a
utility

Paradigm Shift…
1. Hardware is a Programmable Resource2. Scale out, over Scale Up.3. Aim for Stateless (or Centralized State) applications4. Decouple application components5. Balancing act of cost, agility, reliability

“Decoupling” other Resources
• Place static resources in Cloud Storage• Enable a Content Delivery Network (CDN)• Deploy to Multiple Data Centers• Make Geographically Redundant Back-ups
