After the one-hour protection period ends, the system compares the bid price with the market price and checks the resource inventory to determine whether to retain or release the instance.
• 0: After a preemptible instance is created, Alibaba Cloud does not ensure that the instance runs for one hour. The system compares the bid price with the market price and checks the resource inventory to determine whether to retain or release the instance.
