Software Architect's Handbook

Phase D – Technology architecture

Technology architecture, one of the other architecture domains defined in TOGAF, involves the enterprise's infrastructure components. This includes the hardware and software necessary to support the enterprise's business, data, and application architectures.

The goal of this phase is to develop the target technology architecture that will support the enterprise's solutions. An assessment of the enterprise's current infrastructure capabilities is completed and compared with the desired target state so that the gap between them can be identified. From there, a roadmap of the target state for the technology architecture can be created along with the candidate components.
