Agenda

•  Status •  Hybrid Cloud •  Adoption Barriers •  Trends

24/01/2013 3 John Rhoton – 2013

Cloud Essence

•  Simple definition: “resource pooling” •  Attributes –  Virtualization, Multi-tenancy, Automation, Self-service,

Internet Delivery, Elasticity, On-demand provisioning, Utility Pricing, Service Orientation, Outsourcing…

•  Benefits –  Cost Reduction –  Increased Revenue (Agility) –  Faster Growth (Focus)

24/01/2013 4 John Rhoton – 2013

Emotional vs Factual

Status

•  Startups start with cloud – Small, no legacy, unpredictable growth

•  Enterprise – Short term: Dev/test, Collaboration, Security,

New outbound services – Long term: Private-> Hybrid -> Public

24/01/2013 6 John Rhoton – 2013

Private Cloud Optimization

•  Resource Efficiencies – Virtualization

•  Operational Efficiencies – Automation, Chargeback

•  Sourcing Efficiencies – Service Orientation, Modularization, Granular

Security

24/01/2013 17 John Rhoton – 2013

Redundancy

•  Dimensions – Physical – Geographical – Technological – Organizational

•  Horizontal Scalability •  ACID (Atomic Consistent Isolated Durable)

=> BASE (Basic Availability, Soft-state, Eventual consistency) Architect for scale

24/01/2013 18 John Rhoton – 2013

Business Continuity

•  Cold Site •  Warm Site •  Hot Site •  Double-Active
