Spot Instances Are a Mock
Spot Instance Requests are a mock over the on-demand RunInstances path. A request synchronously launches real VMs on the operator's own compute and is then reported active and fulfilled. There is no spot market: no bidding, no price rejection, no interruption and no reclamation, and instances are never taken back.
AMI Launch Permissions Are Refused
An AMI cannot be shared with another account or made public. ModifyImageAttribute refuses LaunchPermission, UserIds, UserGroups, OrganizationArns, OrganizationalUnitArns and OperationType, and ResetImageAttribute resets only description, not launchPermission. Each refusal is InvalidParameterValue. Terraform's aws_ami_launch_permission therefore cannot be created. description is the only image attribute that can be modified or reset.
