AWS Native Peering vs IGW to Build Aviatrix Peering Connection

Aviatrix uses two different techniques to build encrypted peering connection (tunnel). It depend whether Aviatrix HPE (High Performance Encryption) is enabled or not

  1. If HPE is enabled then AWS native peering is used and encrypted tunnel is built over the private network link
    1. Documented here: https://docs.aviatrix.com/HowTos/insane_mode.html#how-does-insane-mode-work
      1. For Insane Mode (HPE) between two gateways, between a Transit GW and a Spoke gateway, or between two Transit GWs (Transit Peering), the Aviatrix Controller automatically creates the underlying AWS Peering connection and builds the tunnels over it
      2. It means 1 cents per GB for send and receive (that is 2 cents per GB)
  2. If HPE is not enabled, then AWS-IGW is used to build the encrypted tunnel
