Anti-DDoS:Anti-DDoS Origin 2.0 (Subscription)

Instance types and selection guide

Anti-DDoS Origin 2.0 provides best-effort protection for assets that are assigned public IP addresses. You can select one of the following instance types:

• Anti-DDoS Origin 2.0 instance of Inclusive Edition for Small and Medium Enterprises: If you have no more than 30 assets that are assigned public IP addresses, the assets reside in the same region, and no more than two DDoS attacks occur on the assets per month, you can select this instance type.

• Anti-DDoS Origin 2.0 Enterprise instance: If you have more than 30 assets that are assigned public IP addresses, the assets reside in multiple regions, and both IPv4 addresses and IPv6 addresses are used, you can select this instance type.

The instance types support both the Insurance and Unlimited protection modes. The following table describes the differences in the mitigation sessions and supported network protocols of the two instance types.

Scenarios that support upgrade

The following section describes the scenarios in which you can increase the number of mitigation sessions and supported regions. You can also increase the clean bandwidth and the number of assets that are assigned public IP addresses based on your business requirements.

• Inclusive Edition for Small and Medium Enterprises (Insurance)

  • If you require more than two mitigation sessions per month, you can upgrade your instance to Inclusive Edition for Small and Medium Enterprises (Unlimited).

  • If you want to protect assets that are assigned public IP addresses and reside in multiple regions, you can upgrade your instance to Anti-DDoS Origin 2.0 Enterprise (Insurance) or Anti-DDoS Origin 2.0 Enterprise (Unlimited).

• Inclusive Edition for Small and Medium Enterprises (Unlimited)

  If you want to protect assets that are assigned public IP addresses and reside in multiple regions, you can upgrade your instance to Anti-DDoS Origin 2.0 Enterprise (Unlimited).

• Anti-DDoS Origin 2.0 Enterprise (Insurance)

  If you require more than two mitigation sessions per month, you can upgrade your instance to Anti-DDoS Origin 2.0 Enterprise (Unlimited).

Billable items

Total fee for an instance = Subscription fee (Fee for the protection mode + Fee for the clean bandwidth + Fee for protected assets that are assigned public IP addresses) + Pay-as-you-go fee (Fee for the burstable clean bandwidth feature)

Subscription

• Fee for the protection mode

  The basic protection fee of the instance. The fee varies based on the protection mode of the instance.

  Protection mode	Unit price (USD per month)
  Inclusive Edition for Small and Medium Enterprises (Insurance)	1,950
  Anti-DDoS Origin 2.0 Enterprise (Unlimited)	6,000

• Fee for the clean bandwidth

  You are charged based on the clean bandwidth. The actual fee is calculated based on the tiered prices and varies based on the protection mode of the instance. If the clean bandwidth values that are listed in the following table cannot meet your business requirements, Contact us.

  Protection mode	Clean bandwidth	Unit price (USD per month per Mbit/s)
  Inclusive Edition for Small and Medium Enterprises (Insurance) and Anti-DDoS Origin 2.0 Enterprise (Insurance)	[0,800]	10
  	(800,4000]	8
  	(4000,8000]	6
  	(8000,12000]	4
  Inclusive Edition for Small and Medium Enterprises (Unlimited) and Anti-DDoS Origin 2.0 Enterprise (Unlimited)	[0,800]	5
  	(800,4000]	4
  	(4000,8000]	3
  	(8000,12000]	2

  For example, you purchase an Anti-DDoS Origin 2.0 Enterprise (Unlimited) instance and select 1,000 Mbit/s for the clean bandwidth. You can calculate the fee for the clean bandwidth by performing the following steps:

  • The fee for 800 Mbit/s of clean bandwidth is calculated based on the pricing tier [0,800]. The monthly fee is calculated by using the following formula: 5 x 800 = USD 4,000.

  • The fee for the additional 200 Mbit/s of clean bandwidth is calculated based on the pricing tier (800,4000]. The monthly fee is calculated by using the following formula: 4 x 200 = USD 800.

  The total monthly fee for the clean bandwidth is calculated by using the following formula: 4,000 + 800 = USD 4,800.

• Fee for the protected assets that are assigned public IP addresses

  You are charged based on the number of protected assets that are assigned public IP addresses. The actual fee is calculated based on the tiered prices and varies based on the protection mode of the instance. If the numbers of protected assets that are assigned public IP addresses listed in the following table cannot meet your business requirements, contact us. For more information, see Contact us.

  Protection mode	Number of protected assets that are assigned public IP addresses	Unit price (USD per month per asset)
  Inclusive Edition for Small and Medium Enterprises (Insurance) and Inclusive Edition for Small and Medium Enterprises (Unlimited)	[0,100]	24
  Anti-DDoS Origin 2.0 Enterprise (Insurance) and Anti-DDoS Origin 2.0 Enterprise (Unlimited)	[0,30]	0
  	(30,100]	24
  	(100,300]	19.2
  	(300,500]	14.4
  	(500,700]	12
  	(700,1000]	9.6

  For example, you purchase an Anti-DDoS Origin 2.0 Enterprise (Unlimited) instance and select 200 protected assets. You can calculate the fee for the protected assets by performing the following steps:

  • The fee for the 30 protected assets is calculated based on the pricing tier [0,30]. The monthly fee is USD 0.

  • The fee for the 70 protected assets is calculated based on the pricing tier (30,100]. The monthly fee is calculated by using the following formula: 24 x 70 = USD 1,680.

  • The fee for the additional 100 protected assets is calculated based on the pricing tier (100,300]. The monthly fee is calculated by using the following formula: 19.2 x 100 = USD 1,920.

  The total monthly fee for the protected assets is calculated by using the following formula: 1,680 + 1,920 = USD 3,600.

Pay-as-you-go

Pay-as-you-go includes the fee for the burstable clean bandwidth feature.

After enabling the Metering Method of 95th Percentile Burstable Clean Bandwidth, the burstable clean bandwidth is five times the clean bandwidth. For example, if the clean bandwidth is 1 Gbit/s, after enabling this option, the clean bandwidth can increase by 4 Gbit/s, totaling 5 Gbit/s.

Traffic that exceeds the allowed peaks for the instance will incur postpaid fees, while traffic within the clean bandwidth will not. The usage of burstable clean bandwidth can be monitored in the Billing Center. For more information, see Query usage details on the Billing Management page.

The following table shows the billing and settlement times, with specific timings subject to the system:

Mitigation sessions

The system logs attack traffic every 5 seconds, resulting in 12 logs per minute. When attack traffic surpasses N Gbit/s, the system calculates the attack duration by summing the values of X and Y, as depicted below. When the total duration exceeds 15 minutes, or 180 logs, a session of best-effort protection is formed.

The red curve in the figure represents the inbound bandwidth of an asset with a public IP address.

• For assets within the Chinese mainland, N is set at 20 Gbit/s.

• For assets outside the Chinese mainland, N is set at 10 Gbit/s.

Business scale estimation

You can estimate your business scale by using the following method:

Sample inbound and outbound bandwidth at five-minute intervals. Calculate the average inbound and outbound bandwidth. Use the greater average value as the bandwidth of the sample point. At the end of each month, sort all sample points in descending order, ignore the top 5% of sample points, and then use the first value of the remaining 95% of sample points as the 95th percentile bandwidth.

Bandwidth overuse

Anti-DDoS Origin allows your clean bandwidth to exceed the clean bandwidth of your Anti-DDoS Origin instance for a short period of time. If the period exceeds 36 hours, the Anti-DDoS Origin mitigation becomes invalid and only basic mitigation capabilities are provided. You can view the details of the overuse in the Billing Center. For more information, see Query usage details on the Billing Management page.

There are two ways to restore Anti-DDoS Origin mitigation capabilities:

1. Wait for automatic restoration in the next billing cycle.

2. Upgrade the Anti-DDoS Origin instance's bandwidth. Once upgraded, protection will automatically restore, and the overuse time will reset.

Overdue payments

Anti-DDoS Origin 2.0 (Subscription) instances use the subscription billing method. Therefore, no overdue payments occur for Anti-DDoS Origin 2.0 (Subscription) instances. Before you can purchase, upgrade, or renew an instance, make sure that your account balance is sufficient. To prevent your services from being adversely affected by instance expiration, we recommend that you enable auto-renewal for your instance.

Expiration

Refunds

After you purchase an Anti-DDoS Origin 2.0 (Subscription) instance, you cannot request a refund for the instance.

Bill query

You can query bills in the Expenses and Costs console. For more information, see Overview of Monthly Bill.
