Too true that Mesos isn't a drop-in replacement. Far from it. There is quite a lot of complexity as well in Mesos.. But looking at it, there are also less moving parts with Mesos compared to OpenStack. As a test, I set up a Mesos Cluster in 3 VM's. It wasn't terribly hard at all. But at work, we had an alarm thrown in nagios about critical ram consumption on a node. So I go and do the migrate. It works.... And it doesn't. It migrated the VM to the same node. I had to do 2 extra flags to tell OpenStack to migrate the node properly. That's just ridiculous, and dumb. And not to mention, but Mesos supports proper handling of VMs and migration. It frustrates me to no end the amount of hand-holding I have to do with anything OpenStack based. Whereas Mesos was "Install, configure, run".. With a large amount of work on Configure.
