Its working pretty well for our 8 person team. We started with ECS, but at some point it wasnt enough, and kubernetes would be too much for our size and expertise (We have around 100 services and do not need autoscaling).

Nomad/Consul/Vault/Fabio are super easy to setup, and its like 10% of the effort of handling your own kubernetes.

Documentation could be worked on, but its getting better.
