Can Google ADK Talk to Amazon Bedrock AgentCore Runtime? A Cross-Cloud A2A Benchmark
Scored daily by a customisable AI persona to surface the most relevant engineering leadership news.
Cross-cloud A2A benchmark between Google ADK and Amazon Bedrock is a deep technical tutorial on multi-agent orchestration.
A cross-cloud benchmark demonstrates an Amazon Bedrock AgentCore-hosted Strands Agents coordinator discovering and delegating to a Google ADK agent on GCP Cloud Run via the A2A v1.0 protocol, with results independently verified against a local MCP exchange-rate tool using live Frankfurter API data. The test measures latency, token overhead, and correctness tradeoffs across three evaluation modes (MCP-only, A2A-only, and verified), comparing performance against a prior Azure Foundry baseline with gpt-5-mini. Numeric agreement is enforced via Python Decimal and relative difference, avoiding LLM-based math evaluation entirely.
