Google ADK Cross Cloud to Amazon Bedrock over A2A

Recent benchmarks tested A2A v1.0 across multiple clouds. A Google ADK master on Cloud Run calling an Amazon Bedrock AgentCore worker revealed six interoperability defects that local tests missed. Additionally, a configuration featuring Microsoft Foundry as the master cloud and Google ADK as the client demonstrated a production-ready architecture. This setup allows Azure to handle orchestration, tools, and arithmetic, while Google Cloud functions as a reachable client for authentication, discovery, and delegation within the framework.
