3. Why Cloud?
Value Proposition
 Provides a way to exploit virtualization and
consolidation
 Aggregates computing resources
 Offers economies of scale
 Offers opportunities to immediately take
advantage of installed
software, hardware, infrastructure, and
applications
 Provides on-demand network access to a
shared pool of configurable computing resources
 Lower IT costs

4. Essential Characteristics
 On-Demand Self-Service
 Broad Network Access
 Resource Pooling
 Rapid Elasticity
 Measured Service

5. Cloud Service Models
 Software as a Service (SaaS)
― The capability provided to the consumer to the
provider’s applications running on a cloud
infrastructure
 Platform as a Service
― The capability to deploy onto the cloud
infrastructure consumer-related or acquired
applications using programming languages and
tools supported by the provider
 Infrastructure as a Service (IaaS)
― The capability to provision
processing, storage, networks and other
computing resources

6. Infrastructure as a Service (Iaas)
 Consumer provisioned
processing, storage, networks, and other
computing resources
 Consumer is able to deploy and run random
software Consumer does not manage or control
the underlying cloud infrastructure
 Consumer has control over operating
systems, storage or deployed applications
 Consumer may have some limited control of
selecting network components (e.g., host firewalls)

7. Benefits of IaaS
 Virtualization and consolidation of IT infrastructure
 Reduction in IT operating expenses and capital
expenses
 Improvement of resource utilization and administrator-
to-server ratios
 Faster time to market through increased efficiency and
automation of standardized solutions
 Simplified integrated management
 Greater visibility into business processes and system
performance to identify redundancies and bottlenecks
 Scaled operations that can meet IT demands, market
dynamics, and business strategy

8. Challenges of Iaas
 Performance and security depend on a cloud
deployment model
― Private
― Community
― Public
― Hybrid
 Global political hybrid environment
― National laws and restrictions
― Need for worldwide agreement on data
securities, privacy policies and data interconnection

9. Adoption of IaaS
 Adoption Process and Issues
―Analyze IaaS offerings in terms of TCO/ROI and
risks (e.g., vendor lock-in, interoperability, existing
IT infrastructure)
―Define a clear IaaS strategy for both private and
public implementation
―Start with a proof of concept – private on-site
deployment (e.g., infrastructure virtualization
project to establish a foundation for future cloud
adoption)

10. Adoption of IaaS
 Considerations
―Consider added business value of private
(outsourced) and public deployment models
(e.g., security and reliability issues, integration
with existing enterprise services
―Public deployments should move only non-
critical, low-risk applications in early transition
stages

11. Summary
Cloud computing
 Offers a centralized, remote facility for computing, leading to
economies of scale in both software and hardware and a reduction in
required administrative management.
 Permits the expense of infrastructure and its management to become
an operational expense rather than a capital investment.
 Offers agility and speed for the use of computing resources on an
immediate basis
 Is not an answer for every problem. Requirements force very high
levels of control and/or security may not be appropriate.
 Is not necessarily cheaper than conventional computing
environments. It is the mix of computing workloads and their cost in
traditional and cloud computing environments which will determine if
savings can be made.
