Since the Alibaba Cloud public cloud was released in 2011, the classic network architecture is used to host ECS instances and serve numerous users in the cloud. In 2014, Alibaba Cloud released VPC-based cloud services, which are more secure, consistent, flexible, and performant than classic network-based cloud services. After years, the VPC network architecture increasingly became the default choice of Alibaba Cloud users. Against this backdrop, Alibaba Cloud starts the end of life (EOL) process for PolarDB clusters in the classic network.
To minimize the impacts on your workloads, Alibaba Cloud provides sufficient time prior to the EOL dates to allow you to devise, test, and execute plan for migrating PolarDB clusters from the classic network to VPCs. Alibaba Cloud provides necessary migration tools, help documents, and technical support to assist in your migration.
Note
The EOL process will not affect PolarDB clusters that are deployed in VPCs.
If you have any questions about this EOL notice for PolarDB classic network clusters, you can contact us.
Dates and impacts
Cloning, renewal, and configuration change for PolarDB classic network clusters unavailable as of 00:00:00 on October 30, 2024
You cannot perform operations such as cloning, renewal, or configuration change on PolarDB classic network clusters any longer. You cannot renew PolarDB classic network clusters that use the subscription billing method.
EOL as of 00:00 on February 28, 2025
PolarDB classic network clusters will be forcibly shut down and released. The following clusters are affected:
Note
You can still use the unexpired PolarDB classic network clusters that use the subscription billing method. Those clusters will not be forcibly shut down and released. However, we recommend that you switch their network type to VPC soon because you cannot renew them any more. For more information, see Switch the network type of an affected PolarDB classic network cluster.
Query all affected PolarDB classic network clusters
Query affected clusters by calling the API operation
You can call the DescribeDrdsInstances operation to query the details of all clusters that belong to your account. If the NetworkType value of a cluster is CLASSIC, the PolarDB cluster uses the classic network.
Query affected clusters in the console
Log on to the PolarDB-X 1.0 console.
In the top navigation bar, select the region where the target instance is located.
In the left-side navigation pane, click Instances.
Click the PolarDB-X 1.0 tab and view the Network Type value of the instance.
