To save cost, we recommend that you release a Pay-As-You-Go instance if you no longer need it.
For a Subscription instance, the instance is automatically released after the billing cycle expires.
To release a Pay-As-You-Go instance, follow the steps below:
Log on to the TSDB console.
Enter the Instances page, and in the Actions column of the instance, click Release.
On the confirmation page, click OK.
