Summary

By · Reviewed & last updated · Part of AWS Tutorial

Wrapping up the AWS track with what you can ship and where to go next.

What you learned + OIDC trust policy

EXAMPLE
# AWS summary

You can now:

- Operate IAM with least privilege and OIDC federation
- Design VPCs with private subnets + endpoints
- Use S3 securely (BucketOwnerEnforced + Block Public Access)
- Run compute on Lambda, Fargate, or EC2 + SSM (no SSH)
- Persist data in RDS, DynamoDB, or Aurora
- Observe with CloudWatch, X-Ray, OpenTelemetry
- Secure with SCPs, GuardDuty, Config, IAM Access Analyzer
- Author IaC with CDK, Terraform, or CloudFormation

# Your next step - OIDC trust policy for GitHub Actions

{
  'Version': '2012-10-17',
  'Statement': [{
    'Effect': 'Allow',
    'Principal': {
      'Federated': 'arn:aws:iam::111111111111:oidc-provider/token.actions.githubusercontent.com'
    },
    'Action': 'sts:AssumeRoleWithWebIdentity',
    'Condition': {
      'StringEquals': {
        'token.actions.githubusercontent.com:aud': 'sts.amazonaws.com'
      },
      'StringLike': {
        'token.actions.githubusercontent.com:sub': 'repo:me/app:ref:refs/heads/main'
      }
    }
  }]
}

Why it matters

AWS rewards discipline. Multi-account + IaC + OIDC + Well-Architected covers most of what production needs. The next-level skills are cost engineering, multi-region resilience, and threat modelling against your specific workloads.

Tip: Tweak the snippet with Try it Yourself », then sit the quiz at the bottom of the page.
