Tokai Academic Cloud ConsortiumA Virtual Consortium Among Six ITCs in National Universities

Contributions to ICA Community1. Describe the current experiences of Tokai

Academic Cloud under development2. Propose a proxy type of Federated Shibboleth

Authentication Handler for Identity Management of Consortium Cloud

3. Present our current activities on the use of VCL for teaching and learning at Nagoya U

Emphasizing cultural aspects on implementing intra and inter-institutional cloud infrastructure

Tokai Academic Cloud

Challenges for Higher Educational Institutions

• Severe Competition among H.E. institutions in the world– Due to the globalization of economics supported

by Information and Communication Technologies

• Severe Budget Cuts– Due to the economic downturn caused by the

world’s economic crisis of 2008

Each institution must strengthen its organizational power

with clear foresight and strategic visions

“Academic Cloud”

• We need to develop ``Academic Cloud'' as cloud computing of the academia, by the academia and for the academia

• The aim is to fulfill diverse needs from constituencies and to accommodate the complexity of academic and administrative computing requirements with affordable costs

Tokai Academic Cloud ConsortiumA Virtual Consortium Among Six ITCs in National Universities

• June, 2009– Having a meeting with the directors

(or the delegation) from each ITC• October, 2009

– Slected as a research project in the grant program of Joint Usage/Research Center for Interdisciplinary Large-scale Informa-tion Infrastructure

– PI: The Director of Nagoya Institute of Technology

– Center: Nagoya U• September, 2009

– IBM Shared University Award• April, 2010

– Grant-in-Aid for Scientific Research for 3 Yrs. (200K US$)

Background Started as a Research

• Most of national universities in Japan, a lot of faculty in IT Center have been getting involved in these operational issues

• Operation itself is the matter of Cloud Computing

• Best practices are still unclear and research issues must be there

For institutional users

Three Main Reasons

1. CAS is better than Shibboleth within organization– Various services provided through Consortium Cloud

require fine-grained authentication and authorization rather than application container delegated authentication

2. LDAP authentication is not allowed for outside services (Shibboleth Authentication only)– Strict security policy in Japanese institutions

3. VCL cannot use other authentication method (Shib and LDAP) when using CAS

• Still under development • Could be an issue against security policy because it may

(3) Current Activities on Use of VCL for Teaching and Learning

at Nagoya University

Tokai VCL

+100 Concurrent Uses Available Potentiallyon About 30 IBM BladeCenters

Nagoya University VCL Pilot

• Currently, five professors have been investigating the use in 2012 semesters:– Mathematics (Mathematica on Linux)– Signal Processing (Scilab on Linux)– Image Processing (Scilab and OpenCV on Linux)– Bio Informatics (PyMOL and Yasara on Linux)– Media Literacy (OpenCast on Linux)

• See Paper for detailed background and scenarios

PyMOL on Ubuntu

Cultural Aspects on Pilot

1. A Very Small Pilot– Again, due to the lack of operation staff and budgets

2. Use of Linux only– A strong opposition to enter Campus Agreement for

dominant OS product

3. Use of Open Source and Shareware-based Applications– Limit of Budget– Scalability
