Anti-DDoS:Manage instances

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.

1. Log on to the Anti-DDoS Pro console.
2. In the left-side navigation pane, choose Assets > Instances.
3. Find the instance that you want to manage and click the icon to the right of Protection Bandwidth in the Status column.
4. 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.

   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

1. Log on to the Anti-DDoS Pro console.
2. 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.

4. Find the instance that you want to upgrade and click Upgrade in the Actions column.
5. On the Upgrade/Downgrade page, configure the parameters based on your business requirements. Read and select Terms of Service, click Buy Now, and then complete the payment.

Renew an instance

Before your instance is released, you can manually renew the instance to extend the subscription period. To avoid the adverse effects of instance expiration on your services, you can also enable auto-renewal before your instance expires. This way, Alibaba Cloud automatically renews the instance when the instance is about to expire.

Manually renew the instance

Before your instance is released, you can manually renew the instance and retain the original configurations of the instance. After the instance is released, you cannot manually renew the instance.

1. Log on to the Anti-DDoS Pro console.
2. 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.
3. In the left-side navigation pane, choose Assets > Instances.
4. Find the instance that you want to renew and click Renew in the Actions column.
5. On the Renew page, configure Subscription, which specifies the renewal duration. Read and select Terms of Service. Then, click Buy Now and complete the payment.

Enable auto-renewal

You can enable auto-renewal only within two or more calendar days before the instance expires. If your instance is about to expire on the following day, you must manually renew the instance.

1. Log on to the Anti-DDoS Pro console.
2. In the top navigation bar, choose Expenses > Renewal Management.
3. On the Manual tab, find the instance that you want to renew and click Enable Auto Renew in the Actions column.
4. In the Enable Auto Renewal dialog box, select an auto-renewal period and click Auto Renew.

After you enable auto-renewal for the instance, you can view the auto-renewal settings of the instance on the Auto tab. Alibaba Cloud automatically deducts fees from your account balance to renew your instance nine calendar days before the expiration date. If you no longer require auto-renewal for your instance, you can enable manual renewal for your instance on the Auto tab.
