adk-a2a-prod-cloud-run takes the 7 ADK agents from the local IDP project and deploys them as independent A2A servers on Cloud Run. Each agent has its own URL, its own container, and scales to zero when it receives no traffic. Communication between agents is via HTTP using the A2A protocol — no shared filesystem.
