Description: Update Stack is a fundamental action in AWS CloudFormation that allows modifying an existing stack with new resources or adjustments to already implemented resources. This action is crucial for keeping cloud infrastructure aligned with the changing needs of an organization. When performing an update, users can add, remove, or modify resources, as well as adjust configurations and parameters. CloudFormation automatically manages dependencies between resources, ensuring that updates are carried out in an orderly and efficient manner. Additionally, stack updates can be performed securely, allowing users to review proposed changes before applying them. This minimizes the risk of service interruptions and ensures that the infrastructure remains stable and functional. The ability to update stacks is essential for managing cloud environments, as it enables organizations to quickly adapt to new demands and continuously optimize their resources.
