Revisiting the Deployment Diagram

The only thing constant in the information technology landscape is that things always change. Such is the case for the textbook ordering system you examined in the previous unit.

The manager of the textbook ordering system has decided to outsource the payment fulfillment processing to an external provider through the use of web services and cloud computing in order to save costs. In addition, the company's Chief of Security has mandated that every application be integrated with the company's Identity Management System (IMS) to ensure all transactions are secured. Because of this, the system architecture has changed and must be depicted in a new design.

Revise the deployment diagram you created previously to add a cloud (node) that is hosted by another company and contains the payment fulfillment services. In addition, add a new application server to host the IMS. Identify the integration technologies used between each new component.

Then, in a 2-3 page report explain the additions to your diagram and justify your integration choices. Analyze the effects this new component has on your system. What issues with your earlier model are resolved? What complications does it introduce?

For purposes of comparison, please include your original diagram as well as your revised diagram.
