What Are the Differences Between Cloud Connect and VPC Peering?

Cloud Connect differs from VPC Peering in the following ways:

  • Interworking capabilities: VPC Peering can only connect two VPCs in the same region, but Cloud Connect can connect multiple VPCs either in the same region or in different regions.
  • Network capabilities: After you create a VPC peering connection, you need to manually configure routes. With Cloud Connect, you do not need to configure routes.
  • Th bearer network: VPC Peering uses the data center network, but Cloud Connect uses a DCI backbone network.
  • Billing: VPC Peering is free. With Cloud Connect, communications between VPCs in the same region is also free, but cross-region communications require a bandwidth package, which is not free.

Table 1 compares these differences.
