Transit Gateway Data Processing Charges #123

Closed rbracewell closed 1 year ago

rbracewell commented 1 year ago

When you centralize NAT gateway using Transit Gateway, you pay an extra Transit Gateway data processing charge — compared to the decentralized approach of running a NAT gateway in every VPC. In some edge cases when you send huge amounts of data through NAT gateway from a VPC, keeping the NAT local in the VPC to avoid the Transit Gateway data processing charge might be a more cost-effective option.

Refer to AWS whitepaper.

It would be nice to surface a control to track this if possible.

Hey @rbracewell , sorry for the long silence on this issue, but thanks for creating an issue for this suggestion!

Is there any way you track these charges or have a way to determine when it's better to have the NAT local for costs? If so, is there any specific cost or billing data you use in that determination? Or any specific AWS CLI commands or APIs to get specific data?

Havent looked at ways to surface this yet was hoping tools like Steampipe and this mod had such a control.

Hey @rbracewell, sorry for the delayed response.

I have checked various docs and API responses of aws_ec2transit and other vpc_ tables but could not find a way to map or track the above information. Please help us with your insights and findings if you have any.
