Explanation:

Refer AWS documentation - SAM Gradual Code Deployment

If you use AWS SAM to create your serverless application, it comes built-in with AWS CodeDeploy to help ensure safe Lambda deployments. With just a few lines of configuration, AWS SAM does the following for you:

Deploys new versions of your Lambda function, and automatically creates aliases that point to the new version. Gradually shifts customer traffic to the new version until you're satisfied that it's working as expected, or you roll back the update. Defines pre-traffic and post-traffic test functions to verify that the newly deployed code is configured correctly and your application operates as expected. Rolls back the deployment if CloudWatch alarms are triggered.
