AWS CloudFormation/CDK Express Mode Speeds Deployments
AWS CloudFormation and CDK now offer an express mode that can speed up infrastructure deployments by up to 4x. This mode completes stack operations once resource configuration is applied, skipping lengthy stabilization checks, which is particularly beneficial for developers and AI agents building infrastructure. Express mode is available now in all supported AWS Regions and can be enabled via the AWS CLI, SDKs, or the AWS Management Console without template changes.

Features (1) ›
- Enable faster infrastructure deployments with CloudFormation and CDK express mode
AWS CloudFormation and Cloud Development Kit (CDK) now include an express mode that significantly reduces deployment times, enabling faster iteration cycles. This mode confirms deployment completion once resource configuration is applied, bypassing extensive stabilization checks. It is designed to benefit developers and AI agents who require quicker feedback loops when building infrastructure incrementally.
Enhancements (3) ›
- Express mode bypasses resource stabilization checks for quicker deployments
Previously, CloudFormation deployments waited for full resource stabilization, including propagation and cleanup, even if not required for the workflow. Express mode allows deployments to finish in seconds after configuration is applied, with background processes continuing independently, such as CloudFront distribution propagation.
- Express mode disables rollback by default for immediate retries
To further expedite the development process, express mode disables rollback by default. This allows for immediate fix-and-retry operations without waiting for rollback procedures, streamlining the debugging and iteration experience.
- Simple activation of express mode via CLI, SDKs, or console
Users can enable express mode by setting the `--deployment-config '{"mode": "EXPRESS"}'` parameter in the AWS CLI or SDKs, or through the AWS Management Console. For AWS CDK users, express mode is activated with the `--express` flag during `cdk deploy`. No modifications to existing CloudFormation templates are necessary.
Notes (1) ›
- Express mode is available across all supported AWS Regions
This new feature is available in all AWS Regions where CloudFormation is supported. Users can refer to the AWS Region table for specific service availability details.
