Mix and Match: Serving a Bedrock Agent to Google and Azure

The multicloud-a2a-subagent project demonstrates interoperability by deploying three research agents across Google Cloud, AWS, and Azure using a single A2A protocol without stored credentials. Google utilizes an ADK agent on Cloud Run, AWS employs a Strands agent on Bedrock AgentCore, and Azure runs an Agent Framework agent on Container Apps. A coordinator queries all three agents to compare hyperscaler frameworks, taking the median or scoring responses to determine differences once the communication protocol is established.
