The application to technology matrix bridging Phase C into Phase D Runs on names the host, Stores in the persistence, Publishes via the distribution channel: seven of the eight applications converge on the shared Kubernetes and PostgreSQL stack, and only the SCADA historian sits off it on the OT network, reaching IT through the Kafka event bus.
The application to technology matrix bridging Phase C into Phase D
The TOGAF Application to Technology Matrix for London Grid Distribution, the bridge from Phase C application architecture into Phase D technology architecture. Eight applications run down the side; five technology platforms run across the top: the Kubernetes platform, the PostgreSQL cluster, the Kafka event bus, object storage and the OT network. Each cell records Runs on, Stores in or Publishes via, and a dash marks no relationship. Seven applications converge on the shared Kubernetes and PostgreSQL stack. The SCADA historian row is tinted in the accent as the one exception: it runs on the OT network and crosses into IT only through the Kafka event bus.
