AWS CloudFormation and CDK now provision infrastructure up to 2x faster by default

AWS CloudFormation and CDK now provision infrastructure up to 2x faster by default, with automatic improvements applied to all stack operations without requiring any changes.

• Infrastructure provisioning accelerated up to 2x faster based on internal benchmarks
• Improvements apply automatically to create, update, delete, and rollback operations
• Largest gains on IAM, S3, Lambda, and VPC resources
• Default mode maintains stabilization checks while completing resources faster
• Express mode available as opt-in for even faster feedback loops
• No action required; works automatically via CLI, SDKs, Console, and CDK
• Available in all AWS Regions where CloudFormation is supported

This enhancement shortens iteration cycles for developers, CI/CD pipelines, and AI agents building infrastructure without requiring any configuration changes.
