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.
