Required Cloud Picture
Every presentation on cloud computing simply must include a lovely photo of a cloud.
Here's my photo of Siesta Key Beach in Sarasota, Fla.
Now that is done, let's discuss the realities and myths of cloud computing.
What Is Cloud Computing?Cloud computing is an outgrowth of several longstanding trends•A slightly new way to address organizations' desire:
• To focus on their key points of added value• To pass other functions on to others who can do them
more efficiently and at lower cost
•Based upon the intersection of:• Outsourcing• Increased use of industry standard systems• Increasingly virtualized environments
Attributes of Cloud Computing• Cloud computing is the use of computing
resources (hardware and software) that are delivered as a service over a network (typically the Internet).
• Usually these resources are:• Self-provisioned• Paid for using a “utility model,” paid by the use• Easily scaled up or down as needed• Typically a multi-tenant environment
Why Cloud Computing?
• Hardware, software & staff cost reduction• No more datacenter space• No budget for new equipment or staff• Agility• Risk reduction

Cloud Computing: The Next Step in the Trend Towards Outsourcing IT
Category Replacement Strategy
Development Purchasing packaged applications and tools
Having own development staff Outsourcing functions where possible
Managing own systems Outsourcing management and operations
Having own datacenter Managed services, collocation
Having own systems Hosting
Cloud computing makes it possible to purchase IT functions as needed, provision them on the fly, and pay for them as
they are consumed.
Categories of Cloud Computing
Category Description
Software as a Service (SaaS) Using a supplier's application over the Internet and paying by the use
Platform as a Service (PaaS) Using a supplier's development platform and running completed applications in supplier's datacenter and paying by the use
Infrastructure as a Service (IaaS)
Using a supplier's systems (physical or virtual) to execute the organization's own applications and paying by the use
Emerging categories Storage as a Service, Security as a Service, Desktop as a Service, Management as a Service, Dev/Test as a Service
What's Holding Back Cloud Adoption?
Concerns about:• Cross-border data flow• Data security• Regulatory compliance• Lack of experience• Lack of standards for migration and
interoperability
Unreasonable expectations
Emerging Standards
• Cloud Security Alliance• Cloud Standards Customer Council• Distributed Management Task Force
(DMTF)• National Institute of Standards (NIST)• Open Data Center Alliance
Emerging Frameworks
• Open Standards• CloudStack• OpenStack
• Vendor frameworks• Amazon• Eucalyptus• Microsoft Azul?• VMware vCloud
