Differences between the subscription and pay-as-you-go modes

Subscription: You can use services only after you have paid for them. For example, you need to purchase a resource package before using it.

  • Note: Assume that you have purchased a resource package in the subscription mode. After the quota of the resource package is exceeded, the excess resources will be billed in the pay-as-you-go mode.

Pay-as-you-go: By default, the pay-as-you-go mode is used after you activate the business edition with your Alibaba Cloud account.

  • Note: In the pay-as-you-go mode, your consumption on the current day will be billed on the next day. Therefore, you must keep your account balance sufficient. If you do not pay an overdue bill within seven days, Alibaba Cloud will send you a notification and deactivate the corresponding services.
