Cloud Computing:
Is it really new?
ByKevin L. Jackson, Engineering Fellow
NJVC, LLC
Association for Computing Machinery
Washington DC Chapter
September 27, 2010
Cloud Computing Not a technology but a new way of provisioning and
consuming information technology
A SOA implemented with a virtualized infrastructure
(compute, storage, networks) enables cloud computing
Key Concerns Standards
Portability
Control/Availability
Security
IT Policy
Management / Monitoring
Ecosystem
Key Benefits Significant cost reductions
Reduced time to capability
Increased flexibility
Elastic scalability
Increase service quality
Increased security
Ease of technology refresh
Ease of collaboration
Increased efficiency
Cloud Computing Components Infrastructure-as-a-Service
Virtualization
Compute
Storage
Network
Platform-as-a-Service
Services to develop, test, deploy, host and maintain applications in the same
integrated development environment
Software-as-a-Service
Network-based access to, and management of, software applications
Activities managed from central locations rather than at each site, enabling
customers to access applications remotely v
Application delivery typically a one-to-many model (single instance, multi-tennant
architecture) than to a one-to-one model

Non-Scalable Applications Are Expensive and Risky
Non-scalable applications suffer from diminishing returns on added resources
As the business grows, per transaction costs INCREASE
At some point the application will hit a wall, leading to: Application crashes (and potential disaster for the business – at huge cost)
Expensive process of re-architecting the application every few months/years

The Goal: Linear Scalability On Demand
No diminishing returns on scale
No code changes when scaling
Drop in another box and increase capacity linearly

Value and Capabilities
Time
Reduce time to deliver/execute mission
Increased responsiveness/flexibility/availability
Cost
Optimizing cost to deliver/execute mission
Optimizing cost of ownership (lifecycle cost)
Increased efficiencies in capital/operational expenditures
Quality

Compute Mobility vs. Data Mobility
Conclusion
Cloud computing delivers real value
Important shift in the consumption and delivery of
information technology
Shift from system integration to service integration
Shift from infrastructure-centric to data-centric
computing (and security)
Driven by societal change
