To provide more secure cloud environments and better user experience, Alibaba Cloud no longer supports the feature to change the network type of an RDS instance that resides in a virtual private cloud (VPC) to the classic network from March 22, 2022.
ApsaraDB RDS supports the following network types:
Virtual private cloud (VPC): Each VPC is an isolated virtual network. VPCs provide higher security than the classic network. We recommend that you select the VPC network type. You can configure route tables, CIDR blocks, and gateways in a VPC. You can also connect your data center to a VPC by using Express Connect circuits or virtual private networks (VPNs). The data center and the VPC comprise a virtual data center. You can use the virtual data center to migrate your workloads to the cloud with no downtime. For more information, see What is a VPC?
Classic network: RDS instances of the classic network type cannot be isolated by using network settings. You can block unauthorized access to the RDS instances of the classic network type only by configuring IP address whitelists or security groups.
For more information about network types, see FAQ about network types.
Discontinued feature
The feature to change the network type of an RDS instance from VPC to classic network is discontinued.
Effective date
March 22, 2022
Impacts and suggestions
Impacts
You cannot change the network type of an RDS instance from VPC to classic network from March 22, 2022.
RDS instances that reside in the classic network are not affected.
Suggestions
VPCs are better than the classic network because VPCs provide you with more secure cloud network environments and better user experience. If you are using the classic network, we recommend you change the network type from classic network to VPC.
