What is the maximum supported throughput of a transit gateway

1

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)?

https://docs.aws.amazon.com/vpc/latest/tgw/transit-gateway-quotas.html

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

    According to the price in Oct-23. Each TGW VPC attachment supports 100 Gbps. There would be still upper limit of TGW itself bandwidth. But would you please elaborate on the use case why the customer needs such large amount of bandwidth per VPC? We should adjust the answer matching to the real scenario - I reckon

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.

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.

    At the scale of the network you mention in the question there are many variables; please reach out to your account team as they can give you far more detailed information than can be shared in this forum.
