What is the maximum supported throughput of a transit gateway

Question

Hi All,

I wanted to know about the actual supported bandwidth by a single TGW!
As per the document linked below, a TGW supports VPC attachments up to 5000 and TGW provides 50Gbps of throughput per VPC.

So should I assume a TGW can give throughput of 5000x50Gbps = 250Tbps (Approx)?

Please help me in getting the clear information, it will help me designing the efficient architecture.

Answer

Hello,
I agree to the above suggestion provided regarding reaching out to the Accounts team/AWS Premium Support Team for TGW.

The reason being that Transit gateway works with multiple elements VPC, DX, VPN and hence there can be a lot of design implications & improvements that can be recommended to you by the AWS team to maximize your throughput without increasing the costs on your account.

Answer

Given the magnitude of the network you're designing I strongly recommend that you reach out to your local AWS account team (and Solutions Architect) to discuss your requirements.
