If you were to look at SmartOS and Smart Data Center, you'd realize that it does have ALL of those components. The place I feel SDC and SmartOS fall short (of DCOS) is in application deployment/orchestration which I think is huge for devs who've had to manage VMs in the cloud.

Another win for DCOS is that it can run anywhere while SmartOS only runs on baremetal. SmartOS does come with some nice goodies like the Manta object storage platform and Manatee, a Postgres replication and failover platform. Application orchestration would make it a contender IMHO.
