What is the focus of the Application Architecture discipline?

The focus of the Application Architecture discipline is primarily on understanding and defining the relationships between applications and business processes. This discipline aims to provide a framework that identifies how applications interact with each other and with the business needs they are designed to support. By analyzing applications in the context of business processes, organizations can ensure that their IT landscape is aligned with business objectives, facilitating efficiency, scalability, and adaptability. The Application Architecture also supports integration efforts and helps in the selection of technologies that meet business requirements effectively.

In contrast to other choices, the inter-relationships of technology infrastructure, data management resources, and the organization of business functions are associated with different aspects of architecture. Although they are important elements of an overall enterprise architecture, they do not specifically cover the interaction and alignment between applications and the processes they serve, which is the essence of the Application Architecture discipline.
