如提,我在 EC2 設定裡面看到這個選項:persistent request

Persistent Requests: Spot Instance requests can be one-time or persistent. A one-time request will only be satisfied once; a persistent request will remain in consideration after each instance termination. This means that with a persistent request, after your request has been satisfied and your instance has been terminated—by you or by Amazon EC2—your request will be submitted again automatically with the same parameters as your initial request. A persistent request will continue submitting the request until you cancel it. A persistent request is useful when you have a large amount of computing that you want to get done but only below a certain price. By using a persistent request, you can launch instances any time the Spot Price is below your maximum price and steadily work through your task.
