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

Essential Characteristics

On-Demand Self-Service Broad Network Access Resource Pooling Rapid Elasticity Measured Service

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

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)

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

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

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

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.
