11. NIST Definition of Cloud Computing
•Cloud computing is 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. This cloud model promotes availability and
is composed of five essential characteristics, three service models, and
four deployment models.
•Note 1: Cloud computing is still an evolving paradigm. Its definitions, use cases, underlying
technologies, issues, risks, and benefits will be refined in a spirited debate by the public and private
sectors. These definitions, attributes, and characteristics will evolve and change over time.
•Note 2: The cloud computing industry represents a large ecosystem of many models, vendors, and
market niches. This definition attempts to encompass all of the various cloud approaches

12. What is “Cloud Computing”?
“…a model for enabling ubiquitous,
convenient, on-demand network access
to a shared pool of configurable
computing resources that can be
rapidly provisioned and released with
minimal management effort or service
provider interaction.”

17. Top 3 Cloud Computing Value Propositions
Private Cloud
1. All about control
1. Costs
2. Deployment Strategy (Roadmap)
3. Timeline
4. Many more….
2. Less security concerns – everything “inside” the firewall
3. Does not need a constant and reliable connection to the Internet
17

18. Top 3 Cloud Computing Value Propositions
Public Cloud
1. Much more control:
1. No need to build, just buy service(s). Can lead to leaner and
1. Over costs
agile SDLC.
2. Roadmap
3. Timeline
2. Financial model shift – to Op Ex. from Cap Ex.
3. Scale capacity linearly as business grows.
18

19. Cloud Computing Value Propositions
Hybrid Cloud
1. Mix and Match Computing Services, as applicable
2. Leverage existing assets and infrastructure.
3. Good balance between control and trying a new paradigm
