To minimize disruptions when integrating a new virtual server that requires a specific pre-configured server image into an AWS environment, what is the best practice when altering an existing CloudFormation template?
Introduce a new resource definition within the Resources section, specifying the required server image through its properties.
Directly adjust the existing resource definitions that provision virtual servers to reference the new server image.
Implement a condition in the Conditions section to trigger the creation of a new virtual server instance upon template update execution.
Incorporate a new mapping in the Mappings section to associate all virtual server resource types with the new server image.
