This document discusses cloud computing architecture and strategies for digital business transformation. It outlines how cloud computing can help CIOs accelerate innovation, lower costs, and reduce risk to meet business objectives. The document then describes different cloud models (IaaS, PaaS, SaaS) and provides examples of technical architectures for VMware and OpenStack private clouds. It emphasizes that success requires starting with a well-defined cloud strategy and developing a comprehensive technical design.

8. But, Cloud Computing has many flavors – IaaS, PaaS, SaaS, Private,
Public, Hybrid – with a host of technologies…
SaaS

PaaS
Platform

IaaS
Infrastructure
as a
Service
• Source and run complete
application from a service
provider
• Quicker adoption
• Faster deployment of end-user
application
• Minimal application
development effort
• Middleware in the cloud
• Rapid application development,
deployment & change
• Fine-grain elasticity of software
services
• Need to buy into PaaS provider’s
vision and constraints
• Private or Public
• Higher utilization of
infrastructure assets
• Lower cost of operations
• Faster provisioning

9. So a comprehensive architectural blueprint is critical to a successful
design and deployment.
