4 Background of Cloud Computing Drawbacks of current software application model Unused parts of software, a waste of money… Solution provided by cloud computing Simplified client side & Data centers Software is delivered by means of service— SaaS Users just pay for each use of service, i.e. pay per use  On-demand service

5 An example of cloud computing

6 Basic types and main user groups of cloud computing applications Extra service Extra service ： Improved function enabled by cloud service Cloud platform Cloud platform ： Applications built on top of the platform SaaS : Applications run in cloud Client （ From David Chappel, A Short Introduction To Cloud Platforms ， 2008 ） Local Deployment

7 Various kinds of cloud Different requirements lead to different kinds of cloud Google ： Application cloud  From improved searching engine to large scale infrastructure service Amazon, SalesForce ： Platform cloud  Brokered SaaS e- e-business platform  Providing infrastructure as service, on which people could build their own applications IBM ： Middleware cloud  Applications are supposed to be delivered on Internet by means of “service”.  Providing middleware based on Internet  Providing computing platform for sale  Blue Cloud Microsoft ： Windows on Internet ？  S+S  Azure ……

8 Standards for cloud computing Various clouds  Construction and connection of clouds should be well ensured. Interfaces defined in current cloud computing resolutions are not compatible with each other. E.g. IBM, Google. Salesforce… ISO standards are needed in this field. Standards about interoperation between cloud and client are missing. People’s confidence cloud computing may be hampered. Standards about interaction between cloud and client will be the focus in the competition between cloud services. RGPS will play an important role!

34 SC32’s Scope Standards for data management within and among local and distributed information systems environments. SC32 provides enabling technologies to promote harmonization data management facilities across sector-specific areas. Specifically, SC32 standards include: reference models and frameworks for the coordination of existing and emerging standards; definition of data domains, data types and data structures, and their associated semantics; languages, services and protocols for persistent storage, concurrent access, concurrent update and interchange of data; methods, languages, services and protocols to structure, organize and register metadata and other information resources associated with sharing and interoperability, including electronic commerce. from

37 MFI-TR: Using RGPS for on demand model selection From resolution of Wuhan Meeting, September, 2008 On-demand cloud selection based on RGPS and ROR

38 Summary Standards about interaction between cloud and client will be the focus in the competition between cloud services. SC32 should take a quick action to catch this opportunity! Wuhan University has foundation for the research on cloud computing standards. We need further support from ISO/IEC JTC1 SC32! We request the subdivision of MFI-8 and TR in the SC32 plenary this year!
