No trend is currently as hot as containers and particularly the popular container management system Docker. Although arguably just maturing, it has already reached almost mythical proportions of cloud hype. Docker would make virtualization superfluous, replace PaaS all together and thanks to unparalleled portability will put a final end to decades of platform and vendor lock-in. As a result there currently is no start-up or cloud provider who has not incorporated Docker prominently in its 2015 strategy.
