AWS CloudFormation rolling deployment policies allow you to update your stack in a rolling manner, which means that you can update a portion of your stack at a time, while the rest of the stack remains operational. This is a cost-effective way to deploy updates to your web application, as it minimizes the amount of downtime that your application experiences.
