Billing Mode

Description

There are yearly/monthly and pay-per-use billing modes. Each one has different advantages and disadvantages.

  • Yearly/Monthly

    You pay in advance for a subscription term, and in exchange, you get a discounted rate. This mode is ideal when the resource use duration is predictable. Billing

  • Pay-per-Use

    Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use. You can purchase or release an EIP at any time. Billing

    Billed Item Description

    If you buy a yearly/monthly EIP, you only need to pay for the bandwidth included in the subscription. You are billed based on your specified bandwidth size and usage duration. There is no limit on how much traffic you can use.

    • Bandwidth: You are billed based on your specified bandwidth size and usage duration. There is no limit on how much traffic you can use.

      After an EIP is purchased, you can change your specified bandwidth size. Although the total traffic is unlimited, your available bandwidth is limited to what was specified at the time of purchase.

    • EIP: If an EIP is not released, it will continue to be billed even if it is not bound to an instance.
    • Traffic: You are billed based on your EIP type and the total amount of traffic going out of the cloud.

      The bandwidth size you set is only used to limit the maximum data transfer rate. To prevent high fees caused by traffic bursts, specify a proper bandwidth size when you buy an EIP.

    • EIP: If an EIP is not released, it will continue to be billed even if it is not bound to an instance.
    If a pay-per-use EIP is added to a shared bandwidth:
    • Shared bandwidth: Only the shared bandwidth will be billed. There will be no additional bandwidth or traffic costs for EIPs added to the shared bandwidth.
    • EIP: If an EIP is not released, it will continue to be billed even if it is not bound to an instance.

    Changing the Billing Mode

    Yearly/Monthly can be changed to pay-per-use (by bandwidth).

    Pay-per-use can be changed to yearly/monthly.

    The new billing mode takes effect immediately.

    An EIP that is billed by traffic on a pay-per-use basis cannot be directly changed to be billed on a yearly/monthly basis. You need to change the EIP to be billed by bandwidth on a pay-per-use basis first, and then change the EIP to be billed on a yearly/monthly basis.

    The new billing mode takes effect immediately.

    The billing mode cannot be changed.
