2. 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 Benefits Key Concerns
 Significant cost reductions  Standards
 Reduced time to capability  Portability
 Increased flexibility  Control/Availability
 Elastic scalability  Security
 Increase service quality  IT Policy
 Increased security  Management / Monitoring
 Ease of technology refresh  Ecosystem
 Ease of collaboration
 Increased efficiency

3. 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

5. 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

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

12. 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
 Environmental improvements
 Experiential improvements

13. Cloud Computing Futures
 Services Integration/Cloud Brokers
 Cloud Measurement/Evaluation Services
 Relational Database Concerns
 Parallel Processing
 Bucket/Big Object Storage
 Compute Mobility vs. Data Mobility

14. 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
