This topic describes how to release an RDS SQL Server instance, which can use the pay-as-you-go or subscription billing method.

Note After an RDS instance is released, its data is deleted immediately. We recommend that you back up the instance data before you release the instance.

Release a pay-as-you-go-based RDS instance


If the RDS instance you want to release is the last read-only instance of a master instance, you must disable the cluster management function of the master instance before releasing the last read-only instance.


  1. Log on to the RDS console.
  2. In the upper-left corner, select the region where the target RDS instance is located.选择地域
  3. Use one of the following two methods to open the Release Instance dialog box:
    • Method 1:

      Find the target RDS instance and in the Actions column choose More > Release Instance.

    • Method 2:
      1. Find the target RDS instance and click the instance ID.
      2. On the Basic Information page, find the Status section and click Release Instance.
  4. In the Release Instance dialog box, click Confirm.

Release a subscription RDS instance

You can open a ticket to apply for releasing a subscription RDS instance.


Will my RDS services be affected if I release a read-only instance?

Yes. Before you release a read-only instance, we recommend that you set the read weight of the read-only instance to 0.
Note After you release a read-only instance, the cached connection still points to this read-only instance. To enable the system to distribute read requests to the other read-only instances, you must reestablish a connection.
