Overview

Introduction

If an IoTDA instance is about to expire but you want to continue using it, renew the subscription within a specified period. Otherwise, resources will be automatically released, and data will be lost and cannot be restored.

Only yearly/monthly IoTDA instances can be renewed. Pay-per-use IoTDA instances can run as long as you have sufficient account balance.

If your subscription is renewed before it expires, all resources are retained and your instances are not affected. For details about the statuses of an IoTDA instance after it expires, see Impact of Expiration.

Renewal Methods

You can renew a yearly/monthly IoTDA instance manually or automatically.

You can renew your subscription across the lifecycle of your IoTDA instance, as shown in Figure 1.

Figure 1 Lifecycle of an IoTDA instance

1. An IoTDA instance is in the Running status from the time when it is purchased to the time when it expires. After the instance expires, its status changes to Expired.
2. If the instance is not renewed upon expiration, it enters the grace period. If it is not renewed after the grace period ends, the status changes to Frozen.
3. If you do not renew your subscription after the grace period ends, your resource enters a retention period. If you do not renew the subscription within the retention period, your resource is automatically deleted.

Both the grace period and retention period for Huawei Cloud International are 15 days.

You can enable auto-renewal anytime before an IoTDA instance expires. By default, the system will make the first attempt to charge your account for the renewal at 03:00, seven days before the expiry date. If this attempt fails, it will make another attempt at 03:00 every day until the subscription is renewed or expires. By default, renewal charges are deducted from your account seven days before the new expiration date. You can change this auto-renew payment date as required.
