The Jupiter Motors worker role

When an RV is finished, a Jupiter Motors driver takes the RV from our factory to the customer. Because custom RVs can cost around US$400,000, and very high-end RVs can cost around US$1,000,000, it's important the customer takes ownership of the RV quickly. When a customer takes ownership of the vehicle, the vehicle is removed from Jupiter Motors' insurance and begins the billing cycles to the customer. In order to take ownership, the customer inspects the vehicle, and accepts delivery by filling out a small form in a custom application on the driver's laptop. The custom application calls our web service and updates the status of the order.

Rather than updating the database directly, the web service places a message in a queue to be processed by our worker role. We are not expecting a high degree of traffic through the web service, but the customer acceptance is a zero-failure process. The built-in failover mechanisms of a queue make it a very attractive way...
