We were thinking of using VyOS for our customer gateway firewalls in AWS for a large infrastructure project, but the AMI image that is available is ancient, we need an updated version of the VyOS AMI in AWS.
Here are our AMI build scripts: https://github.com/vyos/build-ami/
They should be fairly straightforward to use, but if you run into problems, don't hesitate to ask.
The reason for the ancient AMI on the marketplace is that marketplace updates take over a month, while image update after AMI deploy takes minutes. ;)
