I would say that my experience with Docker has been fantastic. I run over 10 Ubuntu Trusty instances on EC2 as 8G instances, mounted with NFS4 to EFS. This makes it super simple to manage data across multiple hosts. From that you can run as many containers as you like, and either mount them to the EFS folder, or just spawn them with data-containers, then export backups regularly with something like duplicity.
I use rancher with it, and it's retarded simple using rancher/docker compose.
Just want to add that I also use it on windows without barely any issues (win 10 x64). I'm not sure how stable it is on Mac OSX but Kitematic is pretty sweet.
The only problems I've had with Docker container are those where processes get stuck inside the container and the --restart=always flag is set. When this happens it means that if you can't force the container to stop, when you reboot the defunct container will restart anyway and cause you the same issue...
My solution to this has been to just create a clean AMI image with ubuntu/rancher/docker and then nuke the old host when it gives me problems. This is made even easier if you use EFS because it's literally already 100% setup once you launch a replacement instance.
