How to Connect to AWS in a Quick & Inexpensive way Part 1: Comparing Connection Types

-

 


Why Connect Your DC to AWS?

  1. Connect to your Internal Web Apps in AWS.
  2. Database Synchronization in AWS.
  3. File Transfers to & from AWS.
  4. Encrypt Traffic between Onprem & AWS.
  5. Temporary (DX) or Backup connection
  6. SDWAN Entry Point

Key differences between the two vpn connection types

S2S IPSEC VPN To TGW

  1. 1.25Gbps per IPSec Tunnel.
  2. IPSec from On-Prem Terminates on the TGW.
  3. Lower Cost & Simpler Architecture.
  4. Quick Setup.

S2S IPSEC VPN Using GRE Tunnels to the TGW


  1. 5.6Gbps per IPSec Tunnel.
  2. IPSec from On-Prem Terminates on an NVA.
  3. Need 1+ NVA ( PA CloudBlade, PA Firewalls, Cisco CSR).
  4. Higher Cost, but Higher Throughput.
  5. More Complex Setup, but Quicker than Using Direct Connect.

    This breakdown of VPN connection options is really clear and practical. I’ve personally struggled with deciding between S2S IPSEC VPN and GRE tunnels for AWS connections, and seeing the trade-offs in cost and throughput helps a lot. Curious to see if you’ll cover Direct Connect options in a future post.
