What happens during an AWS CloudFormation rollback?

What happens during an AWS CloudFormation rollback?

During a rollback, AWS CloudFormation reverts the stack to its last known stable state if the creation or update fails.

How can I trigger a rollback manually?

You can trigger a rollback by updating the stack with a change that causes it to fail, or by using the AWS Management Console to delete the stack.

Are there any costs associated with rollbacks?

Yes, you may incur costs for resources that were created before the rollback, as well as for any resources that are created during the rollback process.

Can I prevent rollbacks from happening?

You can set the 'Rollback on failure' option to false when creating or updating a stack, but this is not recommended as it may leave your stack in an inconsistent state.

What logs can I check to understand rollback issues?

You can check the CloudFormation events in the AWS Management Console or use CloudTrail logs to investigate rollback issues.
