What is AWS Transit Gateway (TGW) Connect?
AWS transit gateway can have different attachments for different use cases. Following are the different attachments that you can terminate on TGW:
- VPC attachment – Terminates VPCs to TGW directly
- VPN attachment – IPSec connection into TGW over Internet
- TGW peering attachment – Peering with another TGW for inter-region traffic
AWS TGW Connect is also a type of TGW attachment which provides an option to connect TGW to a third party appliance inside a VPC over a GRE tunnel. Before setting up the TGW connect attachment to the appliance, you need to have a VPC attachment to the VPC where the appliance is deployed. BGP is used to advertise routes between the TGW and the appliance over the GRE tunnel.
The figure below shows how TGW connect attachment can be used as a transit to connect branches over SD-WAN or any other technology with the cloud workloads inside AWS VPCs.
