Alibaba Cloud Preemptible Instance Survival Intelligent Inspection

Background

Since the market price of the preemptible instances fluctuates with the change of supply and demand, it is necessary to specify the bid mode when creating the preemptible instance, and only when the real-time market price of the specified instance specification is lower than the bid price and the inventory is sufficient can the preemptible instance be successfully created. Therefore, it is particularly important to inspect the preemptible instance of cloud assets. When the preemptible instance is found to be about to be released through inspection, the latest price of all available zones of the current specification of the preemptible instance and the historical price of the changed preemptible instance will be indicated and appropriate treatment advice will be given.
