Application Architecture and WAN Designs

Application Architecture and WAN Designs

You have been tasked with building a payroll program for a large organization with offices spread across the United States. The company has one larger data center that each office connects to via a wide area network (WAN). Write a 5-6 page paper in which you:

Include all of the following. The Network infrastructure layer, which contains the enterprise network architecture (switches, routers, communication links, etc.). The Integrated service layer, services which allow it to be provided over a dispersed or centralized network environment. And finally, the Application layer, where the payroll application would be carried. This will contain sensitive data, so it must be secure.

Explain what type of architecture the new payroll application should use and why.

Identify what types of technology will be involved in the architecture and explain the purpose of each technology.

Create a graphical representation of your recommended architecture. Include charts or diagrams created in Excel, Visio, MS Project, or a freeware alternative. The completed diagrams/charts must be imported into the Word document before the paper is submitted

Identify and describe any potential ethical issues that could arise in connection with the new architecture.

Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA format.

Include charts or diagrams created in Excel, Visio, MS Project, or a freeware alternative. The completed diagrams/charts must be imported into the Word document before the paper is submitted

Analyze and articulate ethical, cultural, and legal issues and their feasibilities among alternative solutions.

Use contemporary CASE tools in process and data modeling.

Use technology and information resources to research issues in systems analysis and development.
