CAS is a leading academic institution and comprehensive research and development center in natural science, technological science and high-tech innovation in China. • It was founded in Beijing on 1st November 1949 on the basis of the former Academia Sinica (Central Academy of Sciences) and Peiping Academy of Sciences.
a public support institution for consistent construction, operation and services of information infrastructure of CAS. • a pioneer, promoter and participator for informtion of domestic scientific research and scientific research management
Operation and Services in CNIC —— Provided by 7 Business Departments Respectively
Scientific Data Center • Scientific Data Center (SDC) is the support facility in charge of the construction, management, operation and maintenance of CAS Informatization Data Application Environment, and has been taking the lead in implementing the CAS Scientific Database Project for more than 20 years. • SDC provides storage services, data services and related application technology services for the entire CAS • SDC hosts the Secretariat of Committee on Data for Science and Technology (CODATA) and the CAS Secretariat for World Wide Web Consortium (W3C). • The vision of SDC is striving to become an important facilitator of exchange and application of scientific data resources, key technology supplier during lifecycle of scientific data, and leader in transforming scientific data into knowledge service.

Hotter and hotter in data research • Mar.29, 2012, the Obama Administration “ Big Data Research and Development Initiative ”($200 Million) : improving our ability to extract knowledge and insights from large and complex collections of digital data • Feb. 11, 2011, 《Science》issued a Special Online Collection: “Dealing with Data” • Sep., 2009, 《Nature》 issued “Data’s shameful neglect”: Research cannot flourish if data are not preserved and made accessible. All concerned must act accordingly. • The Second International Symposium on Dataology & Data Science was held 3 days ago in China • Difficult to discover • Difficult to access • Being lost
Data Driven Scientific Discovery • Data is regarded as the most valuable thing. Scientific discovery based on data intensive computing is now considered as the ''fourth paradigm'' after theoretical, experimental, and computational science. “The impact of Jim Gray’s thinking is continuing to get people to think in a new way about how data and software are redefining what it means to do science." — Bill Gates
Over Moore’s Law in Data • IDC: Data doubles less every 18 months • Huge volume • Rapid increase • Various types and formats
Data Challenge • Scientists are being overwhelmed with exploding scientific data. • Much scientific research needs data distributed in different locations. • There is a growing gap between ability of modern scientific instruments and that of scientists. • It has been a great challenge to view, manipulate, store, move, share, and interpret the massive data.
Scientific Data Deluge in CAS • Large scientific facilities produce huge data • +20 being operation • +20 under construction • Long-Term field observation stations • +100 stations including Ecology, Environment, Space, etc. • Long-Term Research data need to be archived and shared • 100+ institutes Field observation stations Large Scientific facilities

Cloud Computing • It is mixed evolution of grid computing, distributed computing, parallel computing, utility computing, network storage technologies, virtualization, and etc. • It has the characteristics of large-scale, virtualization, high reliability, generality, expandability, on-demand service, extremely cheap, which enables it a popular computing paradigm. • It can bridge the scientists and massive data. • Chinese Academy of Sciences Scientific Data Cloud (CASSDC) is focused on cloud technology to provide facilitated ways for scientists to make use of powerful information infrastructure, massive scientific data and rich scientific software.
