Claude Platform on AWS: What It Is, How It Differs from Bedrock, and When to Use Each

In May 2026, Anthropic launched Claude Platform on AWS, a generally available product that lets you access the Anthropic API through your AWS account — using IAM authentication and AWS Marketplace billing. At first glance it looks like another Bedrock variant. It isn’t.

The key distinction: with Amazon Bedrock, AWS operates the inference stack. With Claude Platform on AWS, Anthropic operates the inference stack. AWS provides the authentication layer, access control, and billing integration. That operational split is what determines every meaningful difference between the two — feature availability, compliance posture, data residency, and cost.

This guide covers what you get, what you don’t, how authentication works, and when each option is the right choice. We research and analyze documentation and public announcements rather than running production AWS deployments ourselves.

The Core Distinction

Two ways to run Claude in the AWS ecosystem:

Why This Exists

Enterprises that are standardized on AWS have two procurement and governance challenges when using Anthropic’s API directly:

1. Billing fragmentation: Anthropic direct charges via credit card or invoice; that’s a separate vendor relationship outside AWS consolidated billing.
2. IAM blind spots: Direct API key auth doesn’t integrate with IAM roles, SCP policies, or CloudTrail audit trails.

Claude Platform on AWS solves both without giving up the feature set. You get full Anthropic capabilities — including features that aren’t available on Bedrock — while billing flows through AWS Marketplace and access is controlled via IAM.

The tradeoff is compliance posture: Anthropic operates the inference stack, which means data processes outside AWS’s security perimeter. That’s a non-starter for HIPAA workloads, which need to stay on Bedrock.

Authentication: Two Methods

Claude Platform on AWS supports two authentication modes.

IAM with SigV4 (Recommended for Production)

Request signing uses AWS Signature Version 4, the same mechanism you use for S3, DynamoDB, or any other AWS service. The IAM service name and action namespace is aws-external-anthropic.

IAM policy actions follow the pattern aws-external-anthropic:<Action>. For inference calls:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "aws-external-anthropic:CreateInference",
        "aws-external-anthropic:CreateMessageBatch"
      ],
      "Resource": "*"
    }
  ]
}

SigV4 signing lets you use temporary IAM credentials (assumed roles, instance profiles, Lambda execution roles) rather than long-lived API keys. This is the right choice for anything running on EC2, ECS, Lambda, or any AWS compute.

API Keys

Claude Platform on AWS also supports Anthropic-issued API keys. The base URL is the same as the SigV4 endpoint. This is the easier path for exploration and local development — the same keys from console.anthropic.com work here if you’ve enabled AWS billing.

Note: Amazon Bedrock API keys do not work on Claude Platform on AWS, and vice versa. These are separate authentication systems with separate endpoints.

What You Get: Full Anthropic Feature Set

The defining characteristic of Claude Platform on AWS is same-day feature parity with the Anthropic platform. When Anthropic launches a new feature — Managed Agents, a new API, a beta capability — it appears on Claude Platform on AWS at launch, not weeks later through the Bedrock pipeline.

Messages API, Files API, Message Batches API

All three are fully available. If your code targets api.anthropic.com today, migrating to Claude Platform on AWS is primarily an auth change — the request format is the same.

Agent Skills

Agent Skills are reusable, shareable skill packages for Claude agents. Available on Claude Platform on AWS; not available on Bedrock.

Managed Agents

Managed Agents — cron-scheduled agents with vault-stored credentials and browser access — are available on Claude Platform on AWS. However, there are functional gaps compared to direct:

• Not available on Claude Platform on AWS: outcome tracking, multi-agent sessions, webhook delivery
• Available on direct only for these specific features

If your Managed Agents use is straightforward (run a scheduled task, use CLI tools, authenticated services), Claude Platform on AWS handles it. If you need outcome callbacks or multi-agent session coordination, stay on Anthropic direct.

MCP Connectors and Code Execution

Both are available. MCP connectors on Claude Platform on AWS let agents reach external tools via the same MCP protocol — useful for agents running in AWS infrastructure that need to reach Jira, GitHub, Slack, or custom MCP servers.

Code execution (the sandboxed interpreter) is also available, which Bedrock does not offer.

What You Don’t Get

HIPAA

This is a hard no. The official AWS documentation is explicit: Anthropic’s HIPAA-ready program is not available on Claude Platform on AWS. If you have HIPAA requirements, use Claude in Amazon Bedrock instead.

The structural reason: HIPAA compliance requires data to process within AWS’s covered infrastructure. Because Anthropic operates the inference stack on Claude Platform on AWS, data exits AWS’s security perimeter. That’s incompatible with HIPAA BAA requirements.

Full Managed Agents Feature Set

As noted above: outcome tracking, multi-agent sessions, and webhook delivery are not available on Claude Platform on AWS. These are available on Anthropic direct but haven’t been extended to the AWS-hosted version.

Bedrock-Specific Features

Cross-model orchestration via Bedrock’s multi-model APIs, Bedrock Knowledge Bases, Bedrock Guardrails, and other Bedrock-native services operate at the AWS layer and are separate from Claude Platform on AWS.

CloudTrail Integration

All API calls made through Claude Platform on AWS are captured in AWS CloudTrail. This is significant for enterprises that require audit trails of AI API usage — who called what, when, from which IAM principal.

CloudTrail events follow the aws-external-anthropic namespace and include the standard CloudTrail fields: request time, user identity, source IP, request parameters (without prompt content, which is not logged), and response metadata.

If your security team needs to demonstrate that AI API usage is auditable, this is the mechanism.

Claude Code on Claude Platform on AWS

Claude Code supports Claude Platform on AWS through the same SigV4 auth path. Configuration:

# Set AWS credentials (if not already configured via instance profile or ~/.aws)
export AWS_ACCESS_KEY_ID=...
export AWS_SECRET_ACCESS_KEY=...
export AWS_REGION=us-east-1

# Point Claude Code to Claude Platform on AWS
claude config set api-provider claude-platform-on-aws

The detailed setup is documented in the Claude Code on Claude Platform on AWS docs. The practical value: teams already using AWS SSO or IAM Identity Center can authenticate Claude Code sessions through existing role assumptions rather than managing separate API keys.

The Decision Map

Use Claude Platform on AWS if:

• Your team is on AWS and wants consolidated billing through AWS Marketplace
• You need IAM-based access control and CloudTrail audit trails for AI API usage
• You want full Anthropic features (Managed Agents, Agent Skills, Files API, MCP connectors, code execution) with AWS auth
• You’re running compute on AWS (EC2, Lambda, ECS) and want temporary credentials rather than API keys
• HIPAA is not a requirement

Use Amazon Bedrock if:

• HIPAA compliance is required
• You need data to remain within AWS’s security perimeter and compliance boundary
• You’re using Bedrock-native features (Knowledge Bases, Guardrails, multi-model orchestration)
• Your IAM policies are already built around Bedrock IAM actions and migration cost is high

Use Anthropic direct if:

• You need full Managed Agents features including outcome tracking, multi-agent sessions, and webhook delivery
• You’re not on AWS or prefer to avoid AWS coupling
• You need maximum flexibility for future provider switching

Pricing

Claude Platform on AWS bills through AWS Marketplace on consumption. Token pricing is the same as Anthropic direct — there is no AWS premium added. The cost difference, if any, comes from operational decisions (regional pricing, data transfer) rather than a markup on inference.

Getting Started

The quickest path to Claude Platform on AWS:

1. Subscribe to Claude Platform on AWS in AWS Marketplace
2. Attach the aws-external-anthropic:CreateInference permission to the IAM role that will make calls
3. Use the Anthropic SDK with SigV4 signing, or swap the API key for temporary role credentials

The official setup path is at docs.aws.amazon.com/claude-platform. The Anthropic API docs cover the SDK-level details.
