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

On May 11, 2026, Anthropic and AWS 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 (Anthropic’s launch post). 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:

Table sourced from the AWS launch announcement, Anthropic’s Claude Platform on AWS vs. Amazon Bedrock comparison, and AWS’s feature-support documentation. Region count reflects general-availability launch (May 2026) per AWS’s own announcement; AWS’s product docs describe rollout as ongoing, so treat this as a snapshot, not a current live count.

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>. The IAM action reference lists 65 actions; for inference and batch calls specifically, the relevant actions are CreateInference (synchronous) and CreateBatchInference (Message Batches API) — not a single combined “message batch” action:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "aws-external-anthropic:CreateInference",
        "aws-external-anthropic:CreateBatchInference"
      ],
      "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 API key authentication as an alternative to SigV4, authorized through the aws-external-anthropic:CallWithBearerToken IAM action. This is the easier path for exploration and local development. Importantly, these keys are not interchangeable with first-party Anthropic keys: AWS’s own authentication docs are explicit that “only API keys created in the AWS Console under Claude Platform on AWS work with this service” — keys generated in the standard console.anthropic.com Claude Console for first-party API access do not work against the Claude Platform on AWS endpoint, contrary to what you might expect.

Note: Amazon Bedrock API keys do not work on Claude Platform on AWS, and vice versa — “Bedrock uses a separate endpoint, authentication flow, and IAM namespace.”

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 (“requires code execution,” per Anthropic’s comparison table).

Managed Agents

Managed Agents — Anthropic’s managed agent harness with cron-scheduled sessions and vault-stored credentials — are available on Claude Platform on AWS, including agents, sessions, environments, credential vaults, memory stores, webhooks, and multiagent orchestration. There are two known functional gaps versus first-party direct access:

• Outcome tracking for agent sessions is not available on Claude Platform on AWS.
• Autonomous-session reauthentication: an AWS-hosted session that runs without any user event must reauthenticate every 6 hours (send any user-role event) or the session ends; first-party direct Managed Agents has no such runtime limit.

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 tracking or long unattended autonomous runs past 6 hours, stay on Anthropic direct.

MCP Connectors and Code Execution

Both are available on Claude Platform on AWS. MCP connectors 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. Per Anthropic’s own docs, “the MCP connector is available on the Claude API, Claude Platform on AWS, and Microsoft Foundry… It is not currently available on Amazon Bedrock or Google Cloud.”

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

What You Don’t Get

HIPAA

This is a hard no. AWS’s feature-support documentation is explicit: “Anthropic’s HIPAA-ready program is not available on Claude Platform on AWS. Customers with HIPAA requirements should evaluate Claude in Amazon Bedrock instead.” The same page notes the service “is not covered by standard AWS compliance programs, certifications, or audit reports (such as SOC, ISO, or HIPAA eligibility)” — it’s a third-party offering layered on AWS billing/IAM, not an AWS-operated service.

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 is not available on Claude Platform on AWS, and unattended autonomous sessions must reauthenticate every 6 hours, a limit that doesn’t exist on Anthropic direct.

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

AWS CloudTrail can capture all requests made through Claude Platform on AWS, classified under the aws-external-anthropic action namespace. Per AWS’s monitoring documentation: workspace and vault operations are logged as Management events by default; inference, batch, file, skill, model, user-profile, and most Managed Agents operations are Data events, which require you to explicitly turn on data-event logging (and incur additional CloudTrail charges) — see the full event-type classification. AWS states plainly that “enabling logging does not provide AWS or Anthropic access to your content beyond what is necessary for billing and service operation.”

This is significant for enterprises that require audit trails of AI API usage — who called what, when, from which IAM principal. If your security team needs to demonstrate that AI API usage is auditable, this is the mechanism, but note that Data events (the ones covering actual inference calls) are opt-in, not on by default.

Claude Code on Claude Platform on AWS

Claude Code supports Claude Platform on AWS through the same SigV4 (or API key) auth path, gated behind an explicit opt-in environment variable rather than a claude config subcommand. Per the official Claude Code docs, configuration looks like:

# Authenticate via the standard AWS credential chain (SSO shown here)
aws sso login --profile my-profile
export AWS_PROFILE=my-profile

# Route Claude Code to Claude Platform on AWS
export CLAUDE_CODE_USE_ANTHROPIC_AWS=1
export ANTHROPIC_AWS_WORKSPACE_ID=wrkspc_01ABCDEFGHIJKLMN
export AWS_REGION=us-east-1

ANTHROPIC_AWS_WORKSPACE_ID is required on every request; AWS_REGION determines the base URL (https://aws-external-anthropic.{region}.api.aws). Claude Platform on AWS is opt-in even with AWS credentials present — if CLAUDE_CODE_USE_BEDROCK or CLAUDE_CODE_USE_FOUNDRY is also set, those take precedence. Run /status inside Claude Code to confirm the resolved provider. 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 outcome tracking for agent sessions, or unattended autonomous Managed Agents runs longer than 6 hours
• 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, denominated in Claude Consumption Units and invoiced monthly in arrears. AWS’s own product page states plainly: “Pricing is the same as accessing directly through the Claude API” — there is no AWS premium added to token pricing. The cost difference, if any, comes from operational decisions (regional pricing, data transfer) rather than a markup on inference. One exception: Anthropic’s docs note a 1.1x pricing multiplier applies if you pin inference to the “US” data-residency geography specifically; the default “global” routing carries standard pricing.
