SOA AND CLOUD COMPUTING
• One can consider cloud computing the extension of SOA out to cloud-delivered resources, such as storage-as-a-service, data-as-a-service, platform-as-a-service -- you get the idea.
• The trick is to determine which services, information, and processes are good candidates to reside in the clouds, as well as which cloud services should be abstracted within the existing or emerging SOA.

THREE LAYERS OF CLOUD
COMPUTING
Software as a Service (SaaS)Finished applications that you rent and customize
Platform as a Service (PaaS)Developer platform that abstracts the infrastructure, OS and middleware to
drive developer productivity
Infrastructure as a Service (IaaS)Deployment platform that abstracts the infrastructure

A “Connectivity Explosion”
• Applications, formats, APIs, protocols,
standards, etc.
• Connected business partners
Connectivity neither trivial nor static:
• Incompatible structures, semantics,
business rules
• No mature standards
• Changes abound
• Not easy to create robust Web services
interfaces
Connectivity becomes more challenging than ever

“Cloud-computing will help to optimize the Federal
data facility environment and create a platform to
provide services to a broader audience of customers.”

IT IS SKEPTICAL
• IT is understandably skittish
about cloud computing.
• However, many of the cloud
computing resources out there
will actually provide better
service than on-premise.
• Security and performance are
still issues.
• Also, control.

CONSIDERING CLOUDS
However, not so fast.
• Not all computing resources should exist in the clouds, private or public.
• Cloud computing is not always cost effective.
• Do your homework before making the move.

CLOUD COMPUTING
A Fit When:
Processes, applications, and dataare largely independent
Points of integration are well defined
Lower level of security is fine
Core internal enterprise architecture is healthy
Web is the desired platform
Cost is an issue
Applications are new
Not A Fit When:
Processes, applications, and data are largely coupled
Points of integration are not well defined
Higher level of security is required
Core internal enterprise architecture needs work
The application requires a native interface
Cost is an issue
Application is legacy

PATH TO THE CLOUDS
Path to clouds: start with the architecture
Understand:
• Mission drivers
• Information under management
• Existing services under management
• Core business processes

STEPPING TO THE CLOUDS
1. Access the mission.
2. Access the culture.
3. Access the value.
4. Understand your data.
5. Understand your services.
6. Understand your processes.
7. Understand the cloud resources.
8. Identify candidate data.
9. Identify candidate services
10. Identify candidate processes.
11. Create a governance strategy.
12. Create a security strategy.
13. Bind candidate services to data and processes.
14. Relocate services, processes, and information.
15. Implement security.
16. Implement governance.
17. Implement operations.
