Cloud Enterprise Network (CEN) connects network instances that are deployed in regions on a global scale. You are charged based on the region where a network instance is deployed. The Alibaba Cloud account that owns the network instance does not affect how fees are charged. You do not need to purchase a bandwidth plan to connect network instances that are deployed in the same region. In this case, you can use the CEN service for free. To connect network instances across regions, you must purchase a bandwidth plan and allocate bandwidth for the cross-region connection. This topic describes the billing of bandwidth plans.

Billing of bandwidth plans

  • Billable item: bandwidth limit.

    The minimum bandwidth limit that you can specify for a bandwidth plan is 2 Mbit/s.

  • Billing methods:
    • Subscription: If you select the subscription billing method, you must complete the payment before you can use the bandwidth plan.

      Subscription bandwidth plans cannot be deleted and are automatically released upon expiration.

    • Pay-as-you-go: If you select the pay-as-you-go billing method, you are charged based on the amount of resource that you use.

      By default, you cannot purchase pay-as-you-go bandwidth plans. If you want to use pay-as-you-go bandwidth plans, submit a ticket.

      We recommend that you delete the pay-as-you-go bandwidth plans that you no longer need. The billing of a pay-as-you-go bandwidth plan stops after you delete the bandwidth plan.

  • Billing cycles:
    • Subscription bandwidth plans: 30 days.
    • Pay-as-you-go bandwidth plans: one day.

      If you use a bandwidth plan for less than one day, the usage duration is rounded up to one day. For example, if you purchase a bandwidth plan at 23:00 and you use the bandwidth plan for less than one day, you are still charged for one day.
