Guide: Multi-Environment AWS Claude Platform Access Setup

This guide walks through implementing Claude Platform on AWS across three environments: production AWS workloads, developer laptops, and external CI/CD pipelines. All environments share a single subscription with workspace-level isolation. The architecture uses a dedicated AI Services account within AWS Organizations, separating billing, subscription management, and workload consumption. Three access patterns are configured: cross-account SigV4 for AWS workloads via EKS, workspace-scoped API keys for developers, and OIDC federation for external environments. Prerequisites include AWS Organizations with multiple linked accounts, AWS CLI v2, and Python 3.12 with specific packages.
