Description: Resource update is the process of modifying an existing resource in AWS CloudFormation. This process allows users to make changes to the configuration of resources that have already been created and managed through CloudFormation templates. When updating a resource, properties can be adjusted, new configurations can be added, or elements that are no longer needed can be removed. This process is essential for keeping cloud infrastructure aligned with the changing needs of applications and services. Resource updates are carried out by modifying the CloudFormation template and subsequently executing a stack update, ensuring that changes are implemented in a controlled and predictable manner. Additionally, AWS CloudFormation offers options to manage how these updates are performed, allowing users to choose between different strategies, such as in-place updates or replacement updates, depending on the nature of the change and service availability requirements. The ability to efficiently and safely update resources is one of the features that makes infrastructure as code tools a powerful method for managing cloud infrastructure.
