Information processing by computers has evolved by repeating 

centralization and distribution.  However, the current trend is toward a “slight centralization.”

That is called “Cloud Computing.”

The cloud services market  was worth 363 billion yen（4.5 billion U.S. dollars*） in 2010. It will increase more than six times in size to reach approximately 2.3 trillion yen （27.9 billion U.S. dollars*） in 2015.Note: The market is expected to expand by approximately 560 billion yen （6.9 billion U.S. dollars*）through policy support for diffusion of cloud services in government, medical care, education, etc . *Converted at the rate of 81yen/U.S. dollar （as of June 1,2011）

Advantages of Cloud Computing 3

■ While Not Being Used → Wasted

■ Unexpected Demand  Increase

→ Cannot be Met

■ Sudden Growth

→ Expansion Can’t Keep Up

■ Periodic Needs

→ Useless During  Off‐season

■ During Emergency Disasters → Outage

■ Security Issues

→ Must be Dealt With Alone

Data Management Backup methods/timing, storage period for backup data, requirements for data deletion, compensation/insurance at times of data leakage/destruction, etc.

SecurityRequirements for public authentication acquisition, encryption level for communication, restrictions for information receivers, confirmation of Information security‐related matters in audit reports, safety measures for secondary storage media, etc.

＜Formulation of A Guide for Protection of Cloud Service Users and Securing of Compliance＞“Guide for Protection of Cloud Service Users and Securing of Compliance” (July, 2011)

・(1) Complementary Protection of Trade Secrets

(2) Securing of Compliance

In Companies Using Cloud Services

・Clarify important matters to be confirmed beforehand

prior to the contract

＜Standardization of Technical Requirements Required in Inter-cloud Collaboration＞

・Research and development has been promoted toward providing cloud computing technology in which multiple, including medium and small, clouds perform advanced collaboration in highly reliable, high-quality, power-conserving cloud services.

・On the basis of the results of the research and development, a proposal was submitted to ITU-T in January, 2011, for technical requirements for functionality for collaborating across multiple cloud systems.

・This proposal has been officially incorporated as an agenda candidate at ITU-T.

＜Implementation of International Dialogue on Cloud Computing＞

・Concerning cloud computing, open data distribution across borders is important, and discussion with many countries is vital.
