Cloud computing is getting tons of press these days. Everyone has a different perspective and understanding of the technology, and there are myriad variations on the definition of the cloud- William Fellows and John Barr at the 451 Group define cloud computing as the intersection of grid, virtualization, SaaS, and utility computing models.

Pillar 1: Dynamic Computing Infrastructure
Pillar 2: IT Service-Centric Approach
Pillar 3: Self-Service Based Usage Model
Pillar 4: Minimally or Self-Managed Platform
Pillar 5: Consumption-Based Billing
