Hello,

I recommend checking the below link which describes all the options you have for all the VIF Types. Specifically the scenario you are looking at is shown as **Option1** Or **Option 2**. In general, if your network is going to expand globally or multi-region we recommend using Direct Connect Gateway which is a global construct you can use to consolidate your connectivity.

Answer

Thanks for the clear description.

If you have only one VPC, you create one VGW and attach it to the VPC (instead of AZs). Direct Connect Gateway is not necessary unless you plan to connect to more than one VPCs in any account that are located in the same or different Regions.

Attaching here the reference architecture from https://docs.aws.amazon.com/whitepapers/latest/aws-vpc-connectivity-options/aws-direct-connect.html and check the document for additional diagrams.
