Update requires: No interruption

docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-get-template.html#using-cfn-updating-stacks-get-stack.CON

When updating a stack, AWS CloudFormation might interrupt resources or replace updated resources, depending on which properties you update. For more information about resource update behaviors, see Update behaviors of stack resources.

Update methods

AWS CloudFormation provides two methods for updating stacks: direct update or creating and executing change sets. When you directly update a stack, you submit changes and AWS CloudFormation immediately deploys them. Use direct updates when you want to quickly deploy your updates.

With change sets, you can preview the changes AWS CloudFormation will make to your stack, and then decide whether to apply those changes. Change sets are JSON-formatted documents that summarize the changes AWS CloudFormation will make to a stack. Use change sets when you want to ensure that AWS CloudFormation doesn't make unintentional changes or when you want to consider several options. For example, you can use a change set to verify that AWS CloudFormation won't replace your stack's database instances during an update.
