This Stock Quote sample addresses the business need of a financial
services company that provides an interactive Web-based stock market service
to its customers.
The company wants to differentiate itself from its
competition by offering tiered levels of service. The company's goal is to
offer delayed stock quotes to their standard customers and real-time
quotes to their premium customers, that is, customers who pay a subscription.
The
company wants to:
- Offer the delayed and real-time stock quote services as a single service,
which dynamically determines which external service to invoke based on the
customer's subscription level.
- If the real-time service is unavailable, route requests to the
delayed service without affecting the running application.
- Log all requests to the service to satisfy audit requirements.

This sample should take approximately 60 minutes to build and
run.
