Speaking of Amazon, I thought that docker was going to hit their bottom line as now people could easily fully utilize their ec2 instances and thus cutting into their already thin margins. However they jumped past this problem with Lambda. Because in the end I don't want to run an operating system. I don't even want to run tomcat. I just want to run a function in tha cloud. Docker makes it easier to shovel around your application while lambda is the next phase of cloud development.
