AWS described how to integrate Claude Code into regulated development in AWS GovCloud (US)
AWS published instructions for connecting Claude Code through Amazon Bedrock in AWS GovCloud (US). For applications requiring audit logs, it recommends the bedrock-runtime interface; the bedrock-mantle interface natively supports Anthropic Messages API.
AWS described the architecture and configuration of Claude Code through Amazon Bedrock in AWS GovCloud (US) for development subject to regulatory requirements, including ITAR. According to AWS, Claude Opus 5.5, Claude Sonnet 5.5 and Claude Sonnet 5 are available in this environment. According to the article, Claude Opus 5.5 and Claude Sonnet 5.5 have FedRAMP Class D certification; Claude Sonnet 5 also has DoD IL4/IL5 authorization. The current certification status must be verified for the specific model.
According to AWS, the bedrock-runtime interface is available in both US-West and US-East and supports Amazon Bedrock Guardrails and invocation logging, meaning records of model calls. The article recommends this interface for applications requiring an audit trail. The bedrock-mantle interface is available only in the AWS GovCloud (US-West) region, natively supports Anthropic Messages API and offers server-side tools, background processing and the Projects feature. According to the article, support for Amazon Bedrock Guardrails and invocation logging is available exclusively through the bedrock-runtime interface.
The setup process includes configuring credentials in AWS CLI and the required permissions. In the Claude Code setup wizard, the user selects the 3rd-party platform option, Amazon Bedrock, an authentication method, the us-gov-west-1 region and specific models. An existing configuration can be changed using the /setup-bedrock command; the /status command is used to verify the model and provider. AWS notes that the suitability of this solution depends on the requirements of the specific organization.
Why it matters
The guide gives development teams a concrete process for integrating assisted coding into an environment intended for US customers with heightened regulatory requirements. The choice of interface affects the availability of audit logs, guardrails and deployment regions; using this architecture alone does not guarantee that the organization’s requirements will be met.
Two audiences, two different impacts
What this means
For individuals
A developer with access to AWS GovCloud (US) can configure Claude Code to work through Amazon Bedrock and verify the model and provider directly in the tool.
For a business
An organization that requires audit logs of model calls for development must account for their availability only through the bedrock-runtime interface when designing its deployment. The bedrock-mantle interface also limits the choice of region to US-West.
