I suspect an announcement re: Docker's acquisition by a major tech player may follow closely on the heels of this news.
For Docker the question is: can they carve out enough of the enterprise IT budget to reach IPO-level revenue growth before either A) their direct competition (Red Hat and Vmware) catches up to them, or B) Big Cloud commoditizes the entire container platform space, eventually nuking the growth of Docker, Red Hat and Vmware alike.
Docker is in a kind of weird place in the market where they're selling as-a-service for on-premise. Puts them in the same place as OpenStack and CloudFoundry for me - the former is already squished; jury's out on the second (IMHO). I don't see their current strategy succeeding, personally.
