Denoid Tucker interviewed at Web 2.0 Expo San Francisco 2011
summary
Defines cloud layers with specific examples—Salesforce and Gmail as SaaS, Google APIs and Microsoft Azure as PaaS, and IaaS as the hardware layer that provides compute, storage, network and security. Claims private cloud runs on dedicated hosts so all VMs are yours, enabling PCI and HIPAA compliance plus control over outbound firewall rules, scalability, onboarding and ongoing management. Predicts an ecosystem of hosted private and shared clouds rather than only a few giants, and warns that centralized infrastructure raises physical security risks.
