Starting October 10, 2022, ApsaraDB RDS for PostgreSQL will roll out instances based on a new architecture. This update significantly improves operational efficiency, elastic management, and overall product stability.
Changes
Starting October 10, 2022, all new instances will use the new architecture.
When you create your first instance that uses the new architecture, you must grant SLR authorization by using an Alibaba Cloud account or a RAM user with the AliyunRAMFullAccess permission. This allows ApsaraDB RDS for PostgreSQL to access the elastic network interface (ENI) service and create a managed ENI on your behalf. If the SLR authorization status is Unauthorized, click Go to Authorize to authorize the service-linked role (SLR).
The managed ENI allows your ApsaraDB RDS for PostgreSQL instance to access other services within your virtual private cloud (VPC). For more information about ENIs, see ENI overview.
Effective date
October 10, 2022
Important notes
-
You only need to grant SLR authorization once.
-
If you call the CreateDBInstance API to create an ApsaraDB RDS for PostgreSQL instance, you must grant SLR authorization before making the call. For more information about SLR authorization, see Service-linked roles. If SLR authorization is not granted, your payment is automatically refunded.
