AWS CloudFormation and CDK express mode speeds up infrastructure deployments by up to 4x

News

This article announces express mode for AWS CloudFormation and CDK, which speeds up infrastructure deployments by up to 4x by completing stack operations immediately after resource configuration is applied.

  • Deployments complete when configuration is applied, skipping extended stabilization checks like traffic readiness and region propagation
  • Enables faster iteration cycles for developers and AI agents building infrastructure incrementally
  • Example: CloudFront distributions deploy in seconds instead of 5-10 minutes for edge location propagation
  • Express mode disables rollback by default for immediate fix-and-retry workflows
  • Activate with --deployment-config '{"mode": "EXPRESS"}' in AWS CLI or cdk deploy --express for CDK
  • Works with all existing CloudFormation templates and nested stacks without changes
  • Available in all AWS Regions where CloudFormation is supported

Express mode enables faster infrastructure development cycles while maintaining proper resource dependency handling and configuration validation.
