Today’s Plan Introduction Lunch Tools Capability Development Wrap up
eResearch infrastructure
Middleware Software programs that provide essential access, communication, accounting, security, trust, and coordination services between the (computational and data) resources of the grid and the higher-level services that use them.
Some types of middleware Collaborative research environments - Video conferencing
- Support for collaboration
Grid services Federated identity & access management - Authentication, authorisation, access control, certification
- Goal is single ‘sign-on’ for distributed resources
Videoconferencing Widely used in CRIs and universities Can be ISDN or IP-based IP-based videoconferencing can be routed over KAREN Different tools for different situations - Access Grid – groups
- EVO – desktop
- High definition
Access Grid Group-to-group collaboration between potentially large numbers of sites Room-based advanced videoconferencing suite with shared applications - Visualisation
- Remote control of instruments
- Data-sharing
- Shared whiteboard
- Shared browser
Access Grid New Zealand nodes
NEES at Auckland
Personal Access Grid
Desktop Collaboration - EVO User operated Web cam and head set on desktop Collaborators go to a web link Cross platform Shared whiteboard and desktop Recorded session No associated costs
EVO (Enabling Virtual Organisations)
Want to try EVO? All the information you need is at http://www.bestgrid.org/index.php/Getting_Started_with_EVO_in_New_Zealand You need a webcam and headset (BeSTGRID offers recommendations) EVO is at http://evo.caltech.edu Email us if you would like to meet in EVO for a quick demo
Videoconferencing interoperability Different systems in use - Different requirements
- Historical
Collaboration requires interoperability Multipoint Control Units (MCUs) and ‘bridging services’ enable different systems to talk to each other Few of these services available in NZ now, but should develop in next couple of years
Virtual Research Environments (VREs), or ‘Collaboratories’ Researchers want spaces where they can easily and securely - Communicate
- In real time, e.g. instant messaging
- Asynchronously, e.g. email, bulletin boards
- Share documents and other resources
- Manage a "virtual organisation" e.g. meeting calendar
What happens now? Researchers use project websites, wikis and email Ad hoc workspaces are created for individual projects Organisational tools can’t be used for collaboration with external partners Technical expertise to set up and maintain
Example VRE: Sakai Web based and researcher driven Announcements Chat rooms Discussion boards Email lists and archive Shared resources (documents and files) Calendar Wiki And more…

My Workspace Tools
Shared Project Workspace
Shared Resources
VREs: Future vision Support day-to-day work by integrating access to - Communication, including audio and video
- Hardware and scientific equipment
- Software applications, e.g. analysis tools
- Automated workflows
- Data repositories and library resources
- Common desktop applications, e.g. email.
Sakai’s Future Vision
What is Grid Computing? The next generation computing infrastructure to support the growing need for computational based science Analogy with power grid User has no knowledge of resource (data or computational) location
A Grid in Action
Driving a Grid Grid tools - Globus, Condor, SunGrid Engine
Scripts Workflows Portal Web service
Kepler Workflow Tool Example of the 'R' system in a Kepler workflow
myExperiment.org
The NZ Grid Scene BeSTGRID - Auckland, Massey and Canterbury with funding from TEC
- Data grid 100 Tbytes
- Computational Grid
- Canterbury
- Massey cluster

Identity Management Defined What is Identity Management? - “Identity management is the set of business processes, and a supporting infrastructure, for the creation, maintenance, and use of digital identities.” The Burton Group (a research firm specializing in IT infrastructure for the enterprise)
Identity Management in this sense is often called “Identity and Access Management” (IAM) What problems do Identity and Access Management address?
Identity and Access Management “Hi! I’m Lisa.” (Identity) “…and here’s my NetID / password to prove it.” (Authentication) “I want to do some E-Reserves reading.” (Authorization : Allowing Lisa to use the services for which she’s authorized) “And I want to change my grade in last semester’s Physics course.” (Authorization : Preventing her from doing things she’s not supposed to do)
Identity Management Today Tedious registration Inconsistent user data Different login processes Different passwords Unprotected resources because of difficulty Expensive inter-institutional access
Tomorrow’s Vision Single login process Many new resources available to users Enlarged user community for resources Authorization independent of location Efficient implementation of inter-institutional access
Shibboleth Authenticate at home organisation Authorise at resource provider without knowing user’s identity
Trust Federations Technologies like Shibboleth need the resource provider and home organisation to trust each other. Australia - Functioning trial federation
- Funding to develop national trust federation (AAF)
New Zealand - Universities looking to join Australian federation
- Project starting to assess organisational IAM capability within the KAREN community
Key tools and technologies are available NZ organisations must start aligning with standards to achieve interoperability Not just technical issues – sharing requires policies and processes, and these can be even more difficult and time-consuming ‘Trust federations’ are emerging - NZ must be part of these if we want to collaborate internationally
