  • Tools of the trade!


Today’s Plan



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

  • High quality video and sound, multiple cameras

  • 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…



Sakai

  • http://sakaiproject.org/

  • International open source development

  • Software for e-learning and e-research

  • 149 production R&E organisations

    • 115 pilots
  • Auckland University’s BeSTGRID hosts a Sakai Collaboration Server for KAREN at http://sakai.bestgrid.org/portal



Sakai Foundation Members



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
  • Other

    • AgResearch
    • VUW


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

  • No user registration or maintenance at resource

  • 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


Closing Observations

  • 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
