Can I Unsubscribe from a CBH Instance?

If you do not need to use CBH instances anymore, or the configured VPC or security group information for an instance is incorrect, you can unsubscribe from the CBH instance.

You can unsubscribe from a purchased cloud service and apply for a full refund unconditionally within five days of the purchase. Each account can request five-day unconditional full refund for 10 times in a year. Handling fees are required if you unsubscribe from a service over 5 days after it is purchased.

Prerequisites

You have the CBH operation permissions.
You have stopped all operations in the mapped CBH system and unbind the EIP from the CBH instance.

Unsubscription Process

To prevent data loss, unsubscribe from a CBH instance by performing the following operations:

Before the unsubscription, back up the system configurations by referring to Backing Up and Restoring System Configurations.
Unsubscribe from the CBH instance. For details, see Procedure.
(Optional only when you have purchased another CBH instance of the same edition as the one you unsubscribed) Restore the new CBH system with system configurations you backed up. For details, see Restoring System Configurations.

After you unsubscribe from a bastion host, the residual resources will be cleared at 03:00 the next day. If you want to delete a security group, wait until the residual resources are cleared.

Procedure

Log in to the management console.
Choose Security & Compliance > Cloud Bastion Host.
Locate the row where the instance you want to unsubscribe from resides, and click More > Unsubscribe in the Operation column.
In the Unsubscribe Instance dialog box, click OK.
Complete the unsubscription.
- The EIP can only be unbound when the instance is unsubscribed. If you want to release the EIP, go to the EIP console and release it manually.
