There's one viable solution to be able to run IPv6 only subnets in AWS, their (or your own) NAT gateways support v6->v4 NAT. So it allows you to create large IPv6 only subnets for your compute services (ec2, ecs, k8s, elb, all supports that), allowing your containers to scale without worrying about IP addresses. Then you use dual stack subnets for other AWS services that may not support IPv6 and your compute services can access them through the NAT gateway.

ECS, ELB and most other services do not support IPv6-only subnets, as mentioned in the article.

ECS does support dual-stack IPv6, but most other services do not support IPv6 at all.
