I would make the Azure version slightly more advanced than the AWS/GCP versions because Azure now has a particularly strong enterprise story around Microsoft Foundry + Agent 365 + Entra + Defender + Purview.
I also want to update two terms in your original architecture for interview accuracy:
Use “Microsoft Foundry” / “Microsoft Foundry Agent Service” rather than treating the older Azure AI Foundry naming as the whole platform.
“Agent 365” is now a real enterprise control plane for discovering, governing, securing and managing agents across Microsoft and third-party ecosystems. It became generally available for the commercial segment on May 1, 2026. (Microsoft Learn)
Azure API Management now has dedicated AI Gateway capabilities, including token quotas, semantic caching, model routing/governance and MCP management. The dedicated AI Gateway tier is currently preview, so for production architecture I would distinguish the generally available APIM AI-gateway capabilities from the preview tier. (Microsoft Learn)
Azure AI Search now also has “agentic retrieval” and underpins Foundry IQ, Microsoft's managed, permission-aware knowledge layer for agents. (Microsoft Learn)
1. Business scenario
We'll use exactly the same financial-services problem:
“Investigate why counterparty ABC breached its exposure limit yesterday and recommend what action should be taken.”
The solution needs:

Don't rely exclusively on vector search.
For financial applications:

"Find policy CR-1024 regarding
BBB- rated counterparties."The exact identifier:
CR-1024is better handled by lexical search.
But:
