I attempted to spin up a DCOS cluster on AWS the day that you Mesosphere opensourced it. I followed the tutorial step by step and the installation failed, I was never able to log in to the admin console. It was completely opaque and I wasn't able to troubleshoot it in any meaningful way. After A couple of hours I gave up and went back to my Mesos setup. It was a very frustrating experience. I'm not sure how it is now but my experience was disappointing.
