Which of the following Architectural Artifacts is most useful in visualizing the dependencies between applications and infrastructure?

System architecture diagrams are specifically designed to visually represent the components of a system and their interrelationships. In the context of APM, these diagrams are essential for illustrating how business applications connect to each other and to the underlying infrastructure components like servers, databases, and networks. This visualization is critical for impact analysis, identifying dependencies for migration planning, and understanding potential points of failure. Other options listed are financial or qualitative and do not depict technical structure.

A. Financial reports

This is incorrect. Financial reports provide cost data but do not illustrate the technical connections between systems.

B. Application cost analysis

This is incorrect. This is a financial artifact focused on the total cost of ownership, not the technical architecture or dependencies.

D. End-user satisfaction surveys

This is incorrect. These surveys provide qualitative feedback on user experience, not a visualization of technical infrastructure dependencies.

"Use dependency views to see the infrastructure that supports an application service." This dependency view is a form of system architecture diagram.

2. Lankhorst, M. (2013). Enterprise Architecture at Work: Modelling, Communication and Analysis (3rd ed.). Springer. Chapter 5, "The Architecture Viewpoints and Views," explains how architecture diagrams (views) are used to communicate the structure and dependencies of systems to different stakeholders.
