1515Claude models run on Anthropic-managed infrastructure. This is a commercial integration for billing and access through AWS. Anthropic is the data processor for inference inputs and outputs. AWS processes billing and identity metadata under the marketplace model. Customers using Claude through Claude Platform on AWS are subject to Anthropic's [data use terms](https://www.anthropic.com/legal).

17Claude Platform on AWS has the following operational characteristics: data may not reside in AWS, inference may route to Anthropic's primary cloud, and subservices may change without notice. Set the [`inference_geo`](https://platform.claude.com/docs/en/build-with-claude/claude-platform-on-aws#data-residency) parameter per request to pin inference to a specific geography.

542542* **Batch processing:** Submit batch requests for high-throughput workloads.
543543* **Prompt caching:** Cache tools, system prompts, and message history to reduce latency and cost. All prompt caching capabilities (5-minute TTL, 1-hour TTL, and automatic caching) are available.
544544* **Files API:** Upload and reference files across requests.
545* **Customer-managed encryption keys (CMEK):** [CMEK](https://platform.claude.com/docs/en/manage-claude/cmek) is available with [AWS KMS](https://platform.claude.com/docs/en/manage-claude/cmek-aws-kms) keys only. Google Cloud KMS and Azure Key Vault keys cannot be registered. Create, validate, and attach keys in the [Claude Console](https://platform.claude.com/docs/en/build-with-claude/claude-platform-on-aws#using-the-claude-console). The `external_keys` Admin API endpoints are not currently available. The key must be in the same AWS region as the workspace it is attached to.

Create and attach keys in the [Claude Console](https://platform.claude.com/docs/en/build-with-claude/claude-platform-on-aws#using-the-claude-console). There is no separate validation step; the key policy is first exercised when a workspace starts using the key, so a key policy problem surfaces at that point rather than at registration. The `external_keys` Admin API endpoints are not currently available. The key must be in the same AWS region as the workspace it is attached to.
546546* **Compliance API:** The [Compliance API](https://platform.claude.com/docs/en/manage-claude/compliance-api) is available. Access is authorized through the AWS IAM [`ListComplianceActivities` action](https://platform.claude.com/docs/en/api/claude-platform-on-aws-iam-actions#compliance).
