Potential Benefits and Concerns
Private Public CloudCloud
• Control over security, data, availability
• Minimal capital requirements, no upfront risk/commitments
• Investment protection
• Legacy integration• Agility
• Efficiencies of vast scale
• CapEx still required
• Limited Agility• Less control over Security
Regulatory concerns• Limited Agility • Regulatory concerns
Cloud Delivery Models: Hybrid Cloud

Public CloudAccessible over the internet
for general consumption
- Multi-tenant – the ability to
Private CloudOperated solely for an organization, typically within the firewall:
yprocess the needs of multiple users with shared resources in a dynamic and transparent fashion
- Elastic and Scalable –resources can expand and contract as neededMetered/Rented some
- Low cost of ownership
- Great control over security, compliance, and QoS
Hybrid CloudCombining the best of Public
- Metered/Rented – some manner of “pay for only what you use”
- Self-Provisioned – “self check-in” at least to some degree
- Internet based – accessible using internet technology,
- Easier integration
- Support existing applications
Combining the best of Public and Private Clouds for
maximum agility, elasticity and security, at minimum cost

Why Move Application to Cloud
16
• Elasticity – resources can be provisioned and de-provisioned in real time to meet workload demandsto meet workload demands
• Utility – resource usage is provided on a “pay as you go” basis, as opposed to the traditional approach of incurring the upfront capitalopposed to the traditional approach of incurring the upfront capital expenses and ongoing operational expenses, even if the resources are under-utilized
• Ubiquity – services from the cloud are available from the world-wide web, enabling user interfaces that go beyond traditional workstations and include cell phones and other appliances
