After you purchase an Anti-DDoS Pro or Anti-DDoS Premium instance, you can manage the instance based on your business requirements. For example, you can modify the burstable protection bandwidth of the instance, configure the burstable clean bandwidth for the instance, and upgrade and renew the instance. This topic describes how to manage instances.
Instance type | Supported operations | Description |
---|---|---|
Anti-DDoS Pro | Modify the burstable protection bandwidth of an instance | The burstable protection bandwidth determines the maximum capability of the instance to defend against DDoS attacks, which indicates the peak traffic of the DDoS attacks that the instance can mitigate. For more information about the burstable clean bandwidth feature, see Burstable protection bandwidth. |
Enable the burstable clean bandwidth feature | After you enable the burstable clean bandwidth feature, you can specify a burstable clean bandwidth to increase the upper limit of the total bandwidth that is supported by the instance. You are charged for the burstable clean bandwidth based on the pay-as-you-go billing method. For more information about the billing for the burstable clean bandwidth feature, see Billing of the burstable clean bandwidth feature. | |
Upgrade an instance | If the specifications of the instance cannot meet your business requirements, you can upgrade the specifications of the instance in the Anti-DDoS Pro console. The specifications include the function plan, clean bandwidth, and the numbers of protected domain names and ports. | |
Renew an instance | If the instance expires, the instance is released. We recommend that you manually renew the instance before the expiration date or enable auto-renewal. | |
Purchase global advanced mitigation sessions | Only Anti-DDoS Pro instances of the Advanced mitigation plan support global advanced mitigation sessions. If the number of advanced mitigation sessions that are provided free of charge by an Anti-DDoS Pro instance of the Advanced mitigation plan per month cannot meet your business requirements, you can purchase global advanced mitigation sessions. For more information about the billing of global advanced mitigation sessions, see Billing of advanced mitigation sessions. | |
Manage tags of instances | After you create a custom tag, you can add the tag to instances that have the same purpose or attribute. This allows you to classify instances and query multiple instances at a time. | |
Anti-DDoS Premium | Upgrade an instance | If the specifications of the instance cannot meet your business requirements, you can upgrade the specifications of the instance in the Anti-DDoS Premium console. The specifications include the function plan, clean bandwidth, and the numbers of protected domain names and ports. |
Renew an instance | If the instance expires, the instance is released. We recommend that you manually renew the instance before the expiration date or enable auto-renewal. | |
Purchase global advanced mitigation sessions | Only Anti-DDoS Premium instances of the Insurance, Secure Chinese Mainland Acceleration (Sec-CMA), and Sec-CMA (Basic) mitigation plans support global advanced mitigation sessions. If the number of advanced mitigation sessions that is provided free of charge by instances of the preceding types per month cannot meet your business requirements, you can purchase global advanced mitigation sessions. For more information about the billing of global advanced mitigation sessions, see Billing of advanced mitigation sessions. |
Modify the burstable protection bandwidth of an instance
You can specify the basic protection bandwidth and burstable protection bandwidth for an Anti-DDoS Pro instance. The burstable protection bandwidth must be greater than or equal to the basic protection bandwidth. To modify the basic protection bandwidth, you must upgrade your instance. To modify the burstable protection bandwidth, you can change the bandwidth value in the Anti-DDoS Pro console or upgrade your instance at any time.
- Log on to the Anti-DDoS Pro console.
- In the left-side navigation pane, choose .
- Find the instance that you want to manage and click the
icon to the right of Protection Bandwidth in the Status column.
- In the Change Burstable Bandwidth dialog box, select a value and click OK. The maximum burstable protection bandwidth that you can specify varies based on the basic protection bandwidth of the Anti-DDoS Pro instance. If the maximum burstable protection bandwidth that you specified cannot meet your business requirements, we recommend that you increase the basic protection bandwidth of the Anti-DDoS Pro instance. For more information, see Upgrade an instance.
Enable the burstable clean bandwidth feature
If your service traffic occasionally spikes, we recommend that you enable the burstable clean bandwidth feature for your Anti-DDoS Pro or Anti-DDoS Premium instance. This helps prevent packet loss when the peak service traffic exceeds the clean bandwidth of your instance.
Limits
Instance type | Maximum clean bandwidth |
---|---|
Anti-DDoS Pro instance of the Profession or Advanced mitigation plan | 5 Gbit/s |
Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan | 1 Gbit/s |
Anti-DDoS Premium instance of the CMA 2.0 mitigation plan | 2 Gbit/s |
Anti-DDoS Premium instance of the CMA, Sec-CMA or Sec-CMA (Basic) mitigation plan | 500 Mbit/s |
- If the clean bandwidth of the instance is 100 Mbit/s, the maximum burstable clean bandwidth is 900 Mbit/s. In this case, the instance can process service traffic of up to 1 Gbit/s.
- If the clean bandwidth of the instance is 1 Gbit/s, the maximum burstable clean bandwidth is 4 Gbit/s. In this case, the instance can process service traffic of up to 5 Gbit/s.
- If the clean bandwidth of the instance is 5 Gbit/s, you cannot enable the burstable clean bandwidth feature.
Procedure
- Log on to the Anti-DDoS Pro console.
- In the top navigation bar, select the region where your instance resides.
- Anti-DDoS Pro: If your instance is an Anti-DDoS Pro instance, select Chinese Mainland.
- Anti-DDoS Premium: If your instance is an Anti-DDoS Premium instance, select Outside Chinese Mainland.
You can switch the region to configure and manage Anti-DDoS Pro or Anti-DDoS Premium instances. Make sure that you select the required region when you use Anti-DDoS Pro or Anti-DDoS Premium. - In the left-side navigation pane, choose .
- Find the required instance and click the
icon to the right of Burstable Clean Bandwidth in the Instance Type column.
- In the Burstable Clean Bandwidth dialog box, configure the parameters and click OK.
Operation Procedure Enable the burstable clean bandwidth feature Turn on Enable Burstable Clean Bandwidth and configure the Metering Method and Burstable Clean Bandwidth parameters. Modify the burstable clean bandwidth Modify the values of the Metering Method and Burstable Clean Bandwidth parameters based on your business requirements. After you change the metering method and re-open the Burstable Clean Bandwidth dialog box, the value of the Metering Method parameter changes to the metering method that you select, and the message "The metering method is changed and the new metering method takes effect next month" is displayed.
Note The new metering method takes effect at 00:00 on the first day of the next month. You can change the metering method up to three times each calendar month. The last metering method that you select takes effect in the next month. You cannot change the metering method on the last day of a calendar month.Disable the burstable clean bandwidth feature Turn off Enable Burstable Clean Bandwidth. Note You can disable the burstable clean bandwidth feature only once a month.Important The burstable clean bandwidth feature is automatically disabled in the following scenarios:- Your instance expires. Expired instances do not provide services.
- Your Alibaba Cloud account has an overdue payment. In this case, all services that are charged based on the pay-as-you-go billing method become unavailable.
To continue using the burstable clean bandwidth feature, you must renew your instance, or settle the overdue payment and enable the feature.
Upgrade an instance
An instance upgrade indicates an upgrade of the instance specifications. After you upgrade your instance, you must pay the price difference for the remaining validity period of the instance.
Procedure
- Log on to the Anti-DDoS Pro console.
- In the top navigation bar, select the region where your instance resides.
- Anti-DDoS Pro: If your instance is an Anti-DDoS Pro instance, select Chinese Mainland.
