The Japan adoption of cloud IaaS is no surprise in the wake of global trends, especially those in the United States. Amazon Web Services (AWS), boasting an overwhelming share of the US, currently leads the public cloud market worldwide. Meanwhile Rackspace and other cloud service providers are driving OpenStack and CloudStack projects, developing new competitive criteria based on the “Cloud Ecosystem” as they move forward.

The release of the Amazon Elastic Compute Cloud (Amazon EC2/S3) by AWS has had a significant impact on the global IT industry. With the emergence of Eucalyptus, compatible with the Amazon EC2 API, open-source cloud infrastructure software for building IaaS layer cloud environments (like OpenStack and CloudStack) are emerging around the globe. Japan is no exception. There are many services based on OpenStack and CloudStack in the market. In April 2009, axsh Co., Ltd. created the Wakame-vdc software as Japan’s first project.

Let me introduce a few specific implementation cases of OpenStack and CloudStack in Japan.


CyberAgent, Inc.

The internet-related services company, CyberAgent, uses an OpenStack-based private cloud for its own development environment. Development speed was one of the reasons they implemented OpenStack. They were able to reduce costs by consolidating their servers with virtualization technology.


Hokkaido University

The Information Initiative Center at Hokkaido University, one of many national universities in Japan, implemented CloudStack for the “Hokkaido University Academic Cloud” in November 2011. The academic cloud has the ability to operate 2,000 virtual machines simultaneously, and is one of the biggest private cloud systems among Japanese universities. Hokkaido University has also opened this resource to other universities and research institutes to support their activities.


NTT Communications Corporation

One of the top telecommunications service providers in the world, NTT Communications, started the CloudStack-based public cloud service called Cloudn in March 2012. NTT Communications offers this low-cost, scalable service with about 150 APIs.

In addition to the above implementation cases, IDC Frontier Inc.’s cloud service, KDDI Corporation’s “Cloud Platform Service” and SCSK Corporation’s “netXCloud” are other great examples of public cloud services in Japan. SCSK’s private cloud appliance “Cloud System Enabler,” UNIADEX’s “U-Cloud,” NISSHO ELECTRONICS and CREATIONLINE, Inc’s cloud services are noteworthy  private cloud services in Japan.

Many cloud service providers have implemented CloudStack technology that are leading partnerships among those providers in the service development phase. The more CloudStack services and solutions that are created by third parties, the more the Cloud-ecosystem accelerates. User-driven environments are gradually created based on those backgrounds.

Upcoming articles will feature trends and the promotion of CloudFoundry and OpenShift (Open-source based PaaS infrastructure software) in Japan.
