Agreed. I'm not sure that dotcloud and App Engine though were the right products though. They have shown that a fully managed cloud solution is not the answer. Barely no company could use it, let alone migrate existing software to a whole new platform. It's limited to a very small niche. Docker and Kubernetes are standalone products. Companies can use them internally and make it work with what they already have.
