What are the handling methods for expired resources under different payment models?

Prepaid Mode: After a resource instance expires, it will be automatically shut down at 00:00 the next day, and the resource will be deleted at 00:10 fifteen days after shutdown. The system will send in-site message reminders to users 7 days, 3 days, 1 day before the expiration date and on the expiration day. If the system is connected to a mail server and the user's email address is valid, in addition to in-site messages, the system will also send reminder emails to the user's mailbox at 9 a.m. 7 days, 3 days, 1 day before the expiration date and on the expiration day. On the day the resource instance is deleted, the system will also send both in-site messages and email reminders. 

 Postpaid Mode: Taking real-time hourly billing as an example, resource instances will be shut down automatically 2 hours after arrears occur and deleted 24 hours afterwards. The system will send a shutdown notification at the full hour following shutdown, a deletion reminder within 12 hours prior to deletion, and a deletion notification after deletion is completed. Both in-site messages and emails are available for all reminders and notifications.
