Change sets allow you to preview how proposed changes to a stack might impact your running resources, for example, whether your changes will delete or replace any critical resources, AWS CloudFormation makes the changes to your stack only when you decide to execute the change set, allowing you to decide whether to proceed with your proposed changes or explore other changes by creating another change set.
In AWS CloudFormation, a change set is a summary of changes that will be applied to a stack. It provides a detailed preview of how the update will modify the resources in the stack without actually making any changes. By creating a change set, the Administrator can review the proposed changes and understand the impact they will have on the infrastructure.
Creating a change set allows the Administrator to validate the proposed changes, verify that they align with the intended modifications, and assess any potential risks or issues before executing the update. It provides an opportunity to review and discuss the changes with stakeholders, ensuring that they are aware of the modifications and their potential implications.
