Phase C, Information Systems ArchitectureDerived from TOGAF

Application to Technology Matrix

Map each application onto the platforms it runs on, stores in and publishes via, the bridge from application to technology architecture.

Application to technology: which platform hosts, stores and distributes each system

Applications run down the side and the five technology platforms run across the top. Runs on names the host, Stores in the persistence and Publishes via the distribution channel, which makes this matrix the bridge from Phase C applications into Phase D technology.

Application to technology: which platform hosts, stores and distributes each system The TOGAF Application/Technology Matrix for London Grid Distribution, the bridge from Phase C application architecture into Phase D technology architecture. Rows are eight applications; columns are five technology platforms: the Kubernetes platform, the PostgreSQL cluster, the Kafka event bus, object storage and the OT network. Cells record Runs on, Stores in or Publishes via. Seven applications converge on the shared Kubernetes and PostgreSQL stack while the emphasised SCADA historian runs on the OT network and publishes across the boundary through Kafka.

Seven of the eight applications converge on the Kubernetes platform and the PostgreSQL cluster, the consolidation Phase D will defend. The emphasised SCADA historian is the deliberate exception: it lives on the OT network and crosses into IT only through the Kafka event bus.

At the Phase C to Phase D handover, to ground platform decisions in where applications actually run today.

What you need and what you get

You'll need
