How does this compare to Redhat's Atomic Host?
Tectonic would be closer to RedHat's Openshift project/product, but that's not quite right either since Tectonic is not a full blown PaaS solution.
Granted, but let's be serious for a moment.
Nobody with widely-recognised components is going to just stop moving up the value chain to selling turnkey systems. That's where the serious bucks are waiting.
I expect that before too long, my employers' sales team will be seeing CoreOS and Docker sales folk as well as the existing competition from Apprenda, Salesforce/Heroku, IBM and Red Hat.
(And, again, I don't speak for my employers).
