What Can I Do If a Subnet Cannot Be Deleted Because It Is Used By Other Resources?

5



The VPC service allows you to create private, isolated virtual network environments. In a VPC, you can manage private IP address segments, subnets, and network gateways. ECSs, BMSs, databases, and some other applications use secure networks created in VPCs.


Subnets in a VPC cannot be deleted if the subnets are used by the following resources:



  • ECS

  • Elastic load balancer

  • VPN

  • Private IP address


Check whether the subnet is used by the preceding resources. If yes, delete all resources in the subnet and delete the subnet.

Can Subnets Communicate with Each Other?

Subnets belong to VPCs. Subnets in the same VPC can communicate with each other. Subnets in different VPCs cannot communicate with each other by default. However, you can create VPC peering connections to enable subnets in different VPCs to communicate with each other.
