Benchmark of six cross-cloud A2A paths provides deep technical data and strategic insight.
Summary
The benchmark evaluated all six directed A2A v1.0 paths among AWS Bedrock AgentCore, Azure Foundry, and GCP ADK on Cloud Run using 38 evaluation cases. The protocol added negligible latency (1.69–25.1 s spread due to remote runtime), while identity, packaging, and timeouts were the actual cost drivers. A critical finding: deploying the final GCP→AWS path surfaced six defects local tests missed, underscoring that cross-cloud A2A requires real integration testing.
