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

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
