Can Subnets Communicate with Each Other?

  • Subnets in the same VPC can communicate with each other by default.
  • VPCs are isolated from each other. Subnets from different VPCs cannot communicate with each other. You can use a VPC peering connection to enable communication between VPCs in the same region.

If subnets have network ACLs associated, network ACL rules should allow communication between the subnets.
