OpenStack replacement?

[Ken D'Ambrosio]

Hey, all.  We're looking to replace our (woooo deprecated) OpenStack 
install.  And while we could absolutely do it with new OpenStack, our 
needs, if anything, have decreased -- K8 is eating a lot of what we used 
to use OpenStack for.  So I was wondering if we really needed to do a 
new OpenStack, or... if there might be an alternative, perhaps a simpler 
one.  I need:
* API interaction
* scheduling
* network-awareness
* flavors of some sort
And, well, it sounds like CloudStack might be exactly what we need.

Any comments, gotchyas?

Thanks!
