This topic describes the billing methods of Anti-DDoS Premium instances of the Mainland China Acceleration (MCA) mitigation plan.

Overview

An Anti-DDoS Premium instance of the MCA mitigation plan can be used only together with an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan. You can use an Anti-DDoS Premium instance of the MCA mitigation plan to reduce access latency for users in the Chinese mainland. If no attacks occur, an Anti-DDoS Premium instance of the MCA mitigation plan accelerates service delivery to users in the Chinese mainland.

After you add your services that are deployed outside the Chinese mainland to an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan, we recommend that you purchase an Anti-DDoS Premium instance of the MCA mitigation plan. To accelerate cross-border service access, you can use an Anti-DDoS Premium instance of the MCA mitigation plan together with an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan. If no DDoS attacks occur, the Anti-DDoS Premium instance of the MCA mitigation plan forwards service traffic to the origin servers. If DDoS attacks occur, traffic is forwarded to the Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan for traffic scrubbing. For more information, see Configure Anti-DDoS Premium MCA.

Notice An Anti-DDoS Premium instance of the MCA mitigation plan does not deliver protection capabilities. An Anti-DDoS Premium instance of the MCA mitigation plan must be used together with an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan.

An Anti-DDoS Premium instance of the MCA mitigation plan supports only the subscription billing method. Before you can use an Anti-DDoS Premium instance of the MCA mitigation plan, you must purchase an Anti-DDoS Premium instance of the MCA mitigation plan. When you purchase an Anti-DDoS Premium instance of the MCA mitigation plan, specify the specifications and the subscription period, and then complete the payment. An Anti-DDoS Premium instance of the MCA mitigation plan provides access acceleration for services that are added to Anti-DDoS Premium within the subscription period.

Pricing

Two versions of the MCA mitigation plan are offered based on the clean bandwidths that are available.
  • MCA V1.0: If no attacks occur, an Anti-DDoS Premium instance of the MCA V1.0 mitigation plan can use up to 100 Mbit/s of bandwidth to process service traffic.

    By default, MCA V1.0 is available on the Anti-DDoS Premium buy page. To purchase MCA V1.0, set Plan to MCA on the buy page.

  • MCA V2.0: If no attacks occur, an Anti-DDoS Premium instance of the MCA V2.0 mitigation plan can use up to 2 Gbit/s of bandwidth to process service traffic.

    MCA V2.0 delivers higher acceleration capabilities than MCA V1.0. Only clean bandwidths that are no less than 1 Gbit/s are available for purchase in MCA V2.0.

    If you want to purchase MCA V2.0, submit a ticket. After your ticket is approved, you can purchase MCA V2.0 on the Anti-DDoS Premium buy page. To purchase MCA V2.0, set Plan to MCA V2.0 on the buy page.

The following table lists the prices of an Anti-DDoS Premium instance of the MCA mitigation plan at different clean bandwidths.

Warning The clean bandwidth of an instance must be greater than the peak volume of the inbound or outbound traffic, whichever is larger, of protected services.

If the actual bandwidth exceeds the clean bandwidth of the instance, throttling and packet loss may occur. In this case, your services may become unavailable, respond slowly, or have high latency for a period of time.

If the clean bandwidths that are listed in the following table cannot meet your business requirements, submit a ticket.
