DOCOMO Develops New Technology that Improves Cloud Service Performance 
Enables Up to 50% Reduction in Service Response Time 
Tokyo, Apr 8, 2013 - (JCN Newswire) -  NTT DOCOMO, INC., Japan's leading
mobile operator and provider of integrated services centered on mobility,
announced today that it has developed a cloud server management technology that
shortens the service response time of cloud services by up to 50%. The source
code that enables this technology to be used with a variety of cloud services
was provided by DOCOMO to the OpenStack Foundation and is a standard feature of
Grizzly, the new version of the OpenStack cloud platform announced on April 4. 
OpenStack is a cloud platform-based software that utilizes server
virtualization technology to virtually operate a single physical server like
multiple servers, and assigns virtual servers to individual cloud services
utilized by customers. The server management technology developed by DOCOMO
enables physical servers that do not utilize server virtualization technology,
which normally slow cloud service response, to be directly assigned to
individual services via OpenStack, thereby speeding up the response time by 10%
to 50%. 
DOCOMO's new technology also offers the following features: 
1. Depending on service usage conditions, the cloud platform can be switched
between virtual and physical servers. 
2. Software conventionally used for virtual server control can be used with
physical servers without altering the software, thanks to compatibility with
the OpenStack application programming interface (API) for virtual servers. 
3. Up to several hundred physical servers can be managed through OpenStack
scalability. Operating systems can be simultaneously installed and updated on
multiple servers. 
As a member of the OpenStack Foundation since 2012, DOCOMO has contributed
source codes and created specifications for physical server management
technologies. The company looks forward to continuing to contribute actively to
the organization and the advancement of cloud services for the mobile
The OpenStack Foundation, a nonprofit organization created to standardize open
