AWS details running Claude Code on Amazon Bedrock in GovCloud

AWS published guidance on deploying Anthropic's Claude Code with Claude Opus 5.5 and Claude Sonnet 5.5 on Amazon Bedrock in AWS GovCloud (US) for organizations with ITAR and FedRAMP requirements. The post covers three configuration paths, the bedrock-runtime and bedrock-mantle endpoints, and recommendations on IAM, quotas, and token cost governance.

• Claude Opus 5.5 and Sonnet 5.5 hold FedRAMP Class D certification on Bedrock
• Claude Sonnet 5 has DoD IL4/IL5 authorization
• bedrock-runtime is in US-West and US-East; bedrock-mantle only in US-West
• AWS advises pinning model versions due to Opus and Sonnet price gap
