There is a huge difference running on VMs that you have zero access to, and actually owning your own VM infrastructure. Yes AWS Lambda runs on Firecracker, however, it could as well running on a FireCheese VM platform and you would be none the wiser, unless AWS publishes this somewhere. I am also not running on Kubernetes, because Kubernetes. AWS ECS and AWS Batch also only handle containerised applications. Even when deploying on EC2 I tend to use containers, as it ensures they keep working consistently if you apply patches to your EC2 environment.
