I've worked on a fargate + lambda migration to Nomad. At this point I definitely would have preferred to have gone with k8s. Nomad is still relatively complex, to the point where K8s is only somewhat more complex but made up with a bigger community and more tooling and features.

Features I miss: - ephemeral containers - dns integration with cloud providers - Up to date tutorials/examples, especially complex examples - Better out of the box validation/linting
