B) Deploy the application into a new CloudFormation stack. Use an Amazon Route 53 weighted routing policy to distribute the load.
C) Create a version for every new deployed Lambda function. Use the AWS CLI update-function-configuration command with the routing-config parameter to distribute the load.
