Anthropic guide: implement multi-environment access for Claude Platform on AWS
Anthropic published a step‑by‑step implementation guide for Claude Platform on AWS (CPonAWS) that shows how to enable inference from three environments—AWS production workloads via cross‑account SigV4, developer laptops via workspace‑scoped API keys, and external services via OIDC federation and short‑lived tokens—using a dedicated AI Services linked account and workspace isolation. The walkthrough includes CLI commands, console instructions, code snippets, and a recommended three‑account topology (payer, AI Services, workload) with examples for IAM roles, workspace ARNs, and region‑specific endpoints.
