7. And the benefits grow with the level of an organization’s cloud
computing maturity.

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