What it shows

  • AWS Direct Connect provides deterministic low latency and zero packet loss.
  • BGP dynamic routing with AS prepending enables automatic failover.
  • IPsec Site-to-Site VPN acts as a resilient backup over public transit.

The takeaway

BGP route prioritization ensures automatic, zero-touch failover from dedicated fiber to encrypted VPN tunnels.
