Description: Stack update in cloud infrastructure management refers to the process of modifying an existing stack, which is a set of cloud resources managed as a single unit. This process allows users to make changes to resource configurations, add new resources, remove obsolete resources, or modify properties of existing resources. Stack updates are essential for keeping cloud infrastructure aligned with changing business needs and for implementing improvements or fixes efficiently. During an update, the management system evaluates the new desired state of the stack and applies the necessary changes, ensuring that resources are updated in an orderly and controlled manner. This process can be performed manually through a graphical user interface, using a command line interface (CLI), or through automated scripts. The ability to update stacks safely and predictably is one of the most valued features of modern cloud management solutions, as it allows developers and system administrators to manage infrastructure as code, facilitating continuous deployment and change management in production environments.
