model
A lightweight, text-only foundation model in Amazon's Nova family, offered via Bedrock for low-latency, low-cost text tasks.
No evidence-backed relationships are recorded.
A step-by-step build of the same Apache Iceberg data agent on Google ADK, AWS Strands and Microsoft Agent Framework measures what a cloud move costs in code, in latency and in storage wiring.
Reality
A discovery-only comparison of A2A agents on three clouds, measured in August 2026, found one protocol producing three auth models and one card whose sole declared interface URL is the container's bind address.
Reality
A grant of InvokeAgentRuntime will not fetch an A2A agent card on Bedrock AgentCore. And the card a Strands agent publishes there runs 2,109 bytes, most of it the agent's own instructions.
Reality
A Bedrock AgentCore agent serving Google and Azure callers over A2A pushes the vendor-specific work into the container contract rather than the agent. The credential claim is the part not yet shown.
Reality
A dev.to hands-on replaces the classifier Lambda with a Step Functions Choice state. The trade is a second Bedrock invocation on every question, including the cheap ones.
Reality
A dev.to walkthrough moves Claude, Nova and Llama IDs out of Lambda code and into AWS AppConfig feature flags. Rollback stops being a deploy, and model choice stops being a code review.
Reality
One research agent, built three times on three hyperscaler frameworks with the same prompt and the same search tool, diverged in nine ways. None of them were protocol problems.
