Amazon MWAA Serverless addressed a validation issue preventing creation of workflows using shared subnets provided via AWS Resource Access Manager. The update aligns subnet ownership validation with the behavior of MWAA Provisioned environments, enabling workflows across shared VPC architectures.

This enhancement simplifies usage for organizations adopting centralized network management and multi-account landing zones, allowing member accounts to leverage shared subnets without workarounds. Projects using Amazon SageMaker Unified Studio Workflows also benefit when configured with shared VPC networking. This support is available in all regions supporting MWAA Serverless.
