What type of architecture does the Technology Architecture phase primarily concern?

The Technology Architecture phase primarily concerns hardware and software solutions because this phase focuses on the technical aspects that support the architecture of an organization. It involves defining the infrastructure needed to support the applications and processes, detailing the technological components that will be employed, including the necessary hardware, software, and network resources.

This phase integrates various technologies to understand how they interface and support the architecture as a whole. The goal is to create a solid foundation through which the organization's IT capabilities can effectively support business functions and processes.

While other types of architecture like business capabilities, information systems, and network infrastructure play important roles within an enterprise architecture framework, they are typically considered in broader contexts or different phases of the architecture development process. Business capabilities relate more to what the organization can accomplish, and information systems focus on the data and processes, while network infrastructure is a subset of the overall technology architecture. Thus, the emphasis in this particular phase is on the integration and specification of the hardware and software that will make up the organization's technology stack.
