CCBS Overview: the Collapse of the Integration
CCBS challenges lies in:The collapse of the integration done by CCBS The integration with the multiple channel frontends
SOA Benefits
Agility◦ Reuse
◦ Cost Saving
◦ Independence from technology
◦ Risk management
◦ Feedback at different levels
◦ More efficient development process
◦ Adequate business infrastructure
◦ Evolutionary approach
SOA Concepts
Services
◦ Business functions
Frontends
◦ the user of the services
Vertical Slicing
◦ Business use cases
Horizontal Slicing
◦ Technical Layers

Benefit Simple, a good starting point Problem The application frontends are still complex
Networked SOA
Benefit unified interface to the basic service layer
Problem Only support a subset of channels directly

The implementation of channel-specific process logic in
distinct services -> PERFECT
Process Layer
Alternative to SOA
Doing nothingApplicable for applications that do not have high business value and thus short expected life.
Not applicable for CCB:
Long history
High business value
Alternative to SOA
EAI: Enterprise Application IntegrationAs late as 1990, a huge demand for EAI.
Failed to deliver a more holistic view to the problems of having to integrate across organizational boundaries
Existing EAI tools can handle at the development time but not at the runtime.
Shared services in SOA can make EAI largely obsolete.
SOA Resource: Recommendation
IBM Websphere SOA Foundation
IBM has been a business Partner with CCB
IBM has expertise in mainframe
IBM has introduced complete solution and professional strategies for SOA
Conclusion
It is
Q&A
