Subscription Tair (Redis OSS-compatible) instances must be renewed before they expire to avoid service interruption. Pay-as-you-go instances do not require renewal — keep enough balance in your account to cover ongoing costs.
Two renewal methods are available:
| Auto-renewal | Manual renewal | |
|---|---|---|
| How it works | The system renews the instance automatically before it expires. | You initiate renewal on demand before the instance expires. |
| Best for | Production environments and long-running workloads where forgetting to renew would cause outages. | Short-term projects, test environments, or workloads with specific billing control requirements. |
| Billing | The system charges your account for the selected renewal cycle (for example, 3 months) each time it renews. If the auto-renewal charge fails 7 days before expiration, you receive a text message or email alert. | You choose the renewal period at the time of payment. |
| Failure behavior | If the auto-renewal charge fails due to insufficient balance, the instance expires and the system does not attempt another auto-renewal. Manually renew the instance before it is released. | N/A |
