Introducing Claude Platform on AWS: Use Anthropic's Native Claude Platform with Your AWS Account

Claude Platform on AWS reached GA on May 11 U.S. Pacific Time. With just an AWS account, you can directly access Anthropic's native Claude Platform, with no separate credentials, contracts, or billing relationship needed. AWS stated it is the first cloud provider to offer a native Claude Platform experience.

The supported features are the same as the platform Anthropic provides directly. You can use the Messages API, Claude Managed Agents (beta), advisor tools (beta), web search, web fetch, MCP connector (beta), agent skills (beta), code execution, and Files API (beta).

The operational model is tied into AWS services.

• Authentication is handled via IAM or API keys based on AWS Signature Version 4.
• Temporary IAM credentials are recommended for high-security environments, while API keys are convenient during the exploration phase.
• Billing is processed as usage-based charges through AWS Marketplace, letting you track AI spend alongside other AWS services.
• Activity is captured in AWS CloudTrail, with workspace operations logged as management events by default and inference activity able to be added via data event logging.

While Anthropic operates the service, the underlying requests and data are processed outside AWS's security boundary. This makes it suitable for teams without regional data residency requirements, and it is presented as a complementary option to Claude models on Amazon Bedrock.

Adoption is centered around workspaces. A workspace is a unit that separates projects, environments, and teams while maintaining centralized billing and management. A workspace ARN lets you allow or deny access to specific workspaces in IAM policies.

• Activate Claude Platform on AWS from AWS Marketplace.
• Create a workspace in the Claude Console.
• Set ANTHROPIC_API_KEY, ANTHROPIC_BASE_URL, and ANTHROPIC_WORKSPACE_ID to connect your SDK or client.
• The Anthropic SDK example calls claude-sonnet-4-6.

Once connected, clients such as Claude Code and Claude Cowork can also attach to the same workspace. In the console, you can view workspaces, AWS IAM principals, and usage by period, and you can track inference records and costs using CloudTrail data events, AWS Cost Explorer, and resource tags. Available regions include 17 regions, including Seoul.
