# AWS hub

This hub documents Amazon Web Services for an AI coding agent: how to fix a call that failed, how to write a call or template that works the first time, and how one service hands off to another. It documents and never acts. Every document cites its sources and carries a checked date.

**Start at `_boot/START.md`.** It explains the layout, the rules that always apply and the calls that read the hub.

| Area | Services |
|---|---|
| Identity and access | IAM, STS, IAM Identity Center, Organizations (SCPs, RCPs), KMS |
| Storage | S3 |
| Compute | Lambda, ECS on Fargate, EC2 and Auto Scaling |
| Networking | VPC, Elastic Load Balancing, CloudFront, Route 53, ACM |
| Databases | DynamoDB, RDS, Secrets Manager |
| Infrastructure as code | CloudFormation, CDK (TypeScript) |
| Observability | CloudWatch Logs and metrics, CloudTrail, OpenTelemetry tracing |
| Messaging | SQS, SNS, EventBridge |

The full map, with each service's guides, error catalogue and patterns, is `reference/overview/services-and-alternatives.md`. Code is TypeScript (Node.js, AWS SDK v3, CDK v2) and AWS CLI v2. The hub assumes the commercial `aws` partition.

Release notes: `changelog/`.
