Platform Decomposition Diagram
The Platform Decomposition Diagram enables you to architect and visualize the technology platform that supports the operations of the organization.
The Platform Decomposition Diagram allows you to visualize TOGAF definitions (not the extensions mentioned above).
•Logical Application Components (example, Enterprise Architecture tool).
•Physical Application Components (example, System Architect).
•Application Services (example a Microservice such as Voice to Text).
•Technology Services (example, VMware).
•Logical Technology Components (example, database).
•Physical Technology Components (example, Microsoft SQL Server 2020).
•Locations (example, a region, city, building, rack, and so on).
Note that System Architect provides a Network Infrastructure Diagram that provides the ability to visualize extensions to the TOGAF metamodel that UNICOM Systems Inc. has created:
•Application Version (example, System Architect 11.4.11.1).
•Device Instance, Server Instance, and Database Instance – which are at Locations.
TOGAF documentation also recommends using the Platform Decomposition Diagram to delineate between hardware and software:
•Software:
•Logical Technology Components (with attributes).
•Physical Technology Components (with attributes).
•Hardware:
•Logical Technology Components (with attributes).
•Physical Technology Components (with attributes).
