ReleaseInstance - Anti-DDoS - Alibaba Cloud Documentation Center

Release an expired Anti-DDoS Proxy instance.

Operation description

After an Anti-DDoS instance expires, it stops providing DDoS attack protection services. Seven days after expiration, it stops forwarding service traffic.

We recommend that you renew your instance before it expires to avoid impacts on service protection and forwarding. You can call DescribeInstances to query the expiration time of an instance. To renew the instance, go to the Anti-DDoS console to perform the operation.
If you do not plan to renew the instance, we recommend that you restore the protected service IP (no longer use the Anti-DDoS IP as the service IP) or service DNS parsing (no longer parse service traffic to the CNAME address of Anti-DDoS) before the Anti-DDoS instance expires. This prevents service traffic from being forwarded to the Anti-DDoS instance and avoids disruption to normal service forwarding when the instance expires.

After the instance expires, you can call this operation to release the specified Anti-DDoS instance.

Note

Before releasing the specified instance, ensure that you have restored the protected service IP or service DNS parsing.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
