AWS CloudFormation Launches Resource Import
Today, AWS CloudFormation is announcing resource import which allows you to bring existing AWS application resources into CloudFormation. With this launch, you can start managing existing resources such as Amazon S3 Buckets or DynamoDB Tables with all the benefits of CloudFormation, regardless of how they were created or managed previously. You can now leverage automation at scale with these resources instead of relying on manual processes or maintaining custom scripts.
