Docker and its container concepts quickly change the way people build applications in cloud computing environments. 　　These changes also have an impact on the network, and the container seems likely to use software to define the functionality of the network. This is because containers enable developers to rethink the way they use computer capabilities-new methods require higher levels of network abstraction technology. 　　This can be discerned from Google's Kubernetes project, which has been open source in June 2014, and can use a proxy technique (which can be categorized as SDN). "It seems to me that ...
