A. Routing configuration, after creating a peering connection, you need to add the routing information of the peering connection, and the VPC terminal node service has already configured the corresponding routing information for the user, and the user does not need to configure it again

B. Communication direction, two-way communication is supported between two virtual private clouds that establish a peer-to-peer connection, and the VPC terminal node only supports the designated port of the VPC where the terminal node is located to access the back-end resource where the terminal node service is located

C. Security, all elastic cloud servers in the virtual private cloud can be accessed by peer-to-peer connections, while VPC terminal nodes can only access single cloud servers created with ndpoint Service, etc.

D. CDR overlap, both peering connections and VPC endpoints are supported
