4040If you need AWS-operated Claude, see [Claude in Amazon Bedrock](https://platform.claude.com/docs/en/build-with-claude/claude-in-amazon-bedrock). Claude Platform on AWS uses a separate capacity pool from both the first-party Claude API and Amazon Bedrock. You can run workloads on more than one platform and fail over between them.
