4.Summary
4. Cloud Computing - The Coming Storm
What is Cloud Computing?
• Cloud computing is a technology that uses the internet and central remote
servers to maintain data and applications. Cloud computing allows consumers
and businesses to use applications with internet access.
• Data can be Accessed via Internet anywhere from world
without installation of any software or server.
• User Centric – Easier for group members
to collaborate
• Task Centric – User’s need is more important
than features of application
• Powerful – All resources together create a
wealth of computing power
• Programmable – Automated distribution of computing power and data

5. Cloud Computing - The Coming Storm
What Cloud Computing “IS NOT”?
• It is not Network Computing
Application and Data are not confined
to any specific Company’s Server
No VPN Access
Encompasses multiple companies,
multiple servers and multiple networks
• It is not Traditional Outsourcing
Not a contract to host data by 3rd party Hosting Business
No subcontracting for computing services for specific outside firm

6. Cloud Computing - The Coming Storm
So exactly what Cloud Computing is?
• A style of computing where massively scalable IT-enabled capabilities
are provided "as a service" over the network

13. Cloud Computing - The Coming Storm
Software as a Service (SaaS)
• Applications (word processor) or application services (schedule, calendar,
etc.) execute in the “cloud” using the interconnectivity of the internet to
propagate data
• Custom services are combined with 3rd party commercial services via
orchestration to create new applications
• Requires investment to build an enabling layer with governance, security
and data management functionality
• May require integration with back-office systems
• Pay-as-you-go model
SaaS will disrupt the application management functions for both internal IT and
outsourcers
Cloud Computing
PricewaterhouseCoopers Slide 13
14. Cloud Computing - The Coming Storm
What are the benefits & challenges of SaaS?
Benefits Challenges
• Speed • Extension of the security model
• Reduced up-front cost, potential to the provider (data privacy and
for reduced lifetime cost ownership)
• Transfer of some/all support • Governance and billing
obligations management
• Elimination of licensing risk • Synchronization of client and
vendor migrations
• Elimination of version
• Integrated end-user support
compatibility
• Reduced hardware footprint • Scalability
Strong governance required to prevent lines of business from purchasing
application services externally without IT involvement
Cloud Computing
PricewaterhouseCoopers Slide 14
15. Cloud Computing - The Coming Storm
Platform as a Service (PaaS)
• Applications are built in the “cloud” on the platform using a variety of
technologies
• Simplifies orchestration of cloud services
• Development, testing, and production environments (servers, storage,
bandwidth, etc.) are billed monthly like hosting
• Pay-as-you-go model
• Environments scale up & down at the click of a button
• Concerns include code & data privacy, security and scalability
PaaS will disrupt the application development and management functions for
internal IT

16. Cloud Computing - The Coming Storm
What are the benefits & challenges of PaaS?
Benefits Challenges
• Pay-as-you-go for development, • Governance
test, and production environments • Tie-in to the vendor
• Enables developers to focus on
• Extension of the security model to
application code the provider
• Instant global platform
• Connectivity
• Elimination of H/W dependencies
and capacity concerns
• Inherent scalability
• Simplified deployment model
Strong governance required to prevent lines of business from building
applications without IT involvement
PricewaterhouseCoopers Slide 16
17. Cloud Computing - The Coming Storm
Infrastructure as a Service (IaaS)
• Compute resources (processors, memory, storage, bandwidth, etc.) are
provided in an as-needed, pay-as-you-go model
• Able to provide from single server up to entire data centers
• Creates new opportunities such as Cloud bursting: shifting usage spike
traffic to alternate resources
• Infrastructure scales up and down quickly to meet demand
• Built on a utility computing architecture to host a SOA application layer
IaaS will disrupt the infrastructure management functions for both internal IT
and outsourcers
Cloud Computing
PricewaterhouseCoopers Slide 17
18. Cloud Computing - The Coming Storm
What are the benefits & challenges IaaS?
Benefit Challenges
• Higher return on assets through
• Portability of applications
higher utilization
• Reduced cost driven by • Maturity of systems
• Less hardware
management tools
• Less floor space from smaller • Integration across the Cloud
hardware footprint boundary
• Higher level of automation • Extension of internal security
from fewer administrators
models
• Lower power consumption
• Able to match consumption to
demand
IaaS is the onramp for corporate IT to Cloud Computing!

20. Why should we care - The gathering storm
What are the Cloud Computing opportunities?
• Next evolutionary step in computing with >30yrs of momentum
• Requires a new way of thinking, new processes, new skills, and new tools
• Enables the business to work around IT departments
• Companies will reduce IT operating costs and improve agility
• Clients should consider cloud computing as part of their blueprint refresh,
application rationalization, and outsourcing activities
• Client should investigate cloud strategies with their systems management,
application and outsourcing vendors
Cloud Computing will meet prime time in the 2010 timeframe

22. The Storm is Coming
Summary
• Cloud Computing is an organizing principle for buyers
• Focus is on faster, cheaper, better applications
• IT will have to enable the company to use outside providers
then compete with them to provide services
• New models will emerge to drive growth and reduce costs
• Get educated first, identify pilot opportunities second
• Software as a Service is the short term opportunity,
Infrastructure as a Service the long term, Platform as a
Service has limited value
