Joyent. + DTrace available + Great predictable performance + Solaris + no VM + fast non-capped network - client tools are written in node.js (but you can write your own if you really care) Doesn't matter to me, but might to some people: - Relatively few datacenters - Solaris (they do have KVM too, so you can run whatever, but then you lose the many benefits of zones) Also don't matter to me, but might to some people: + completely open source stack, so you could install the same environment in your private datacenter + it does not use openstack
