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
• Data storage, transfer and synchronisation
• Resource scheduling, monitoring and management
• Workflow management
• Federated identity access management
• Authentication, authorisation, access control,
  certification
• Goal is single sign-on for distributed resources

6
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

7
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

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

21
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

22
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

23
What happens now?

• Researchers use project websites, wikis and email
• Ad hoc workspaces are created for individual
  projects
• Organisational tools cant be used for
  collaboration with external partners
• Technical expertise to set up and maintain

24
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

25
Sakai

• http//sakaiproject.org/
• International open source development
• Software for e-learning and e-research
• 149 production RE organisations
• 115 pilots
• Auckland Universitys BeSTGRID hosts a Sakai
  Collaboration Server for KAREN at
  http//sakai.bestgrid.org/portal

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.

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

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! Im Lisa. (Identity)
• and heres my NetID / password to prove it.
• (Authentication)
• I want to do some E-Reserves reading.
• (Authorization ? Allowing Lisa to use
  the services for which shes authorized)
• And I want to change my grade in last semesters
  Physics course.
• (Authorization ? Preventing her from doing
  things shes 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

41
Tomorrows 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

42
Shibboleth

• Authenticate at home organisation
• Authorise at resource provider without knowing
  users identity

Credit Ken Klingenstein, Director, Internet2
Middleware and Security
43
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

44
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
