3. What is Cloud Computing?
Cloud Computing – NIST Definition: “A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction”

4. Five Key Cloud Attributes
Shared / pooled resources
Broad network access
On-demand self-service
Scalable and elastic
Metered by use

5. Shared / Pooled Resources: Resources are drawn from a common pool
What is Cloud Computing?
Shared / Pooled Resources:
Resources are drawn from a common pool
Common resources build economies of scale
Common infrastructure runs at high efficiency

6. Open standards and APIs Almost always IP, HTTP, and REST
What is Cloud Computing?
Broad Network Access:
Open standards and APIs
Almost always IP, HTTP, and REST
Available from anywhere with an internet connection

7. On-Demand Self-Service: Completely automated
What is Cloud Computing?
On-Demand Self-Service:
Completely automated
Users abstracted from the implementation
Near real-time delivery (seconds or minutes)
Services accessed through a self-serve
web interface

8. Resources dynamically-allocated between users
What is Cloud Computing?
Scalable and Elastic:
Resources dynamically-allocated between users
Additional resources dynamically-released when needed
Fully automated

9. Services are metered, like a utility Users pay only for services used
What is Cloud Computing?
Metered by Use:
Services are metered, like a utility
Users pay only for services used
Services can be cancelled at any time

10. IaaS PaaS SaaS Three Service Delivery Models
