Comment from Tadahiro Yasuda, President of Creationline Inc.

We are very happy to present KUSANAGI RoD, the Docker version of the super fast virtual machine KUSANAGI, that we developed with Prime Strategy. We decided on dogfooding our corporate site with a migration to KUSANAGI RoD. The results were much more than we even expected. We hope that many people can experience the merits of Docker by using KUSANAGI RoD.
