Previously, sharing infrastructure values like VPC IDs or database endpoints across account boundaries required manual copying or SSM parameter coordination. The new function accepts a target stack name, output key, IAM role ARN, and optional Region, then resolves the value automatically during template processing. In CDK, cross-account and cross-Region references now use this function automatically, removing the need for custom resources and SSM parameters, and eliminating deployment deadlocks when refactoring cross-stack dependencies. The feature is available in all AWS Regions where CloudFormation is supported. ## Full article daily.dev links to this article rather than hosting it.
