💬 Discussion 5 — Choosing a Fallback Order (20 pts)

For a production system spanning Bedrock, Vertex AI, and OpenRouter, what would your fallback order be, and why? In your initial post (150+ words), pick a concrete scenario (e.g., a customer-facing support agent, an internal coding assistant, a batch document-processing pipeline) and lay out the exact order you'd try providers/models in when the primary one fails or rate-limits. Justify your ordering using at least two of this week's concepts: authentication overhead, region/model availability, routing suffixes, or gateway-level retry/fallback behavior. Then respond to at least two classmates, specifically challenging or building on their ordering — would their choice hold up under a regional outage? Under a sudden cost spike? Under a compliance requirement that forbids data leaving a specific region?
