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
• Fear, Uncertainty and Doubt • Increased Effort – Evaluation – Negotiation – Integration – Implementation
• Reduce CAPEX benefits
Plan early, think objectively
24/01/2013 5 John Rhoton – 2013
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 14 John Rhoton – 2013
Compliance
Enforce Logical Barriers
Global Internet versus National Laws
24/01/2013 15 John Rhoton – 2013
Identity Federation
Identity challenges • Password
proliferation • Weak
authentication • Support costs • User
productivity Implement Identity Standards (SAML, SCIM)
24/01/2013 16 John Rhoton – 2013
Confidentiality
• Data Governance – Data loss prevention
• Compartmentalization
• Encryption
Classify data, Select and Combine Options
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
Multi-dimensional redundancy is critical

Lock-in vs. Cloud Stacks
Proprietary Hardware
Proprietary Software
Open Source
Consortium Driven
Balance ease with flexibility
24/01/2013 20 John Rhoton – 2013
Summary
• Private cloud is the starting point • Public cloud is the final destination • Multiple stages of hybrid cloud in between • Security challenges real but addressable • Redundancy is critical for availability
