Nomad is that. We run Nomad quite successfully at SeatGeek, and I know of several Very Large Companies™ doing so at scale as well. One of them even has a fruit logo.
We are running the OSS version of Consul, Nomad, and Vault. While the enterprise versions provide some items that could be interesting, they are not necessary given our workflow, and I'd bet that the majority of development shops out there wouldn't need them either (though I am certainly more than happy to play with them!).
