How Postman runs Agent Mode for 40 million developers on Amazon Bedrock
Not a pilot. Postman scaled Agent Mode to 40 million developers on Amazon Bedrock—here's the architecture that actually works at that scale.
Why it matters
Postman and AWS published a detailed operational blueprint for running agents in production at massive scale, focusing on tool sprawl control, schema-based reads, and context management. This is practical deployment engineering, not a product announcement—the patterns apply to any enterprise building agents for millions of users.

Publisher excerpt: Building an AI agent that works in a demo is a different problem from running one for 40 million developers. Postman and AWS share the architectural patterns behind Agent Mode: controlling tool sprawl, exposing schema-based reads, and treating context as the real bottleneck, plus how it runs on…
