AWS has introduced a new refactor feature in the AWS Cloud Development Kit (CDK) that enables cloud engineers to safely rename and reorganize their infrastructure as code without the risk of data loss or downtime. This feature simplifies the refactoring process by leveraging AWS CloudFormation's capabilities, allowing developers to focus on code rather than resource configuration. However, experts advise using this feature judiciously and highlight that other Infrastructure as Code tools have different approaches to similar challenges.

AWS CDK will end support for Node.js 18.x on November 30, 2025, following its end of life on April 30, 2025. Users are strongly encouraged to upgrade to Node.js 22.x to continue receiving security updates, new features, and technical support, as remaining on an unsupported version poses security risks and compatibility challenges. A transition period is provided until December 1, 2025, to facilitate this migration.

Migrating from the Serverless Framework to the Cloud Development Kit (CDK) involves a manual process of preserving resources, recreating them in the CDK, and importing them to maintain functionality. The author shares insights from their own migration experience, including steps to prevent resource deletion, compare CloudFormation outputs, and deploy a sample application that demonstrates the migration techniques.
