# American Express Position Paper for Web Services Workshop

1/10/2007

## Overview:

American Express is investigating Web Services and Service Oriented Architecture (SOA) in order to leverage the costs savings that are realizable from using component-based or SOA solutions.

Web Services componentization/SOA relates to using a loosely-coupled, messaged-based model for interaction among software systems. This approach conceptually moves us towards building a repository of reusable components for various organizational and project levels.

## Statement of major problem:

To facilitate rapid development and deployment of Web Services an integration framework that is highly repeatable is needed to facilitate Web Service integration in a cost effective manner. The component deliverables of this framework must be widely accepted in the financial services industry.

## Use Cases:

- B2B
- Components used by multiple internal systems

## Issues/discussion points:

- Testing Web Services with Partners or between internal systems, repeatable processes
- Federated Identity, external partner security requirements
- End-to-end data encryption
- Web Service management
- Web 2.0
- REST based services

## Recommendations:

None at this time.
