Title: Evolution of a Service Oriented Grid foreGovernment


1
Public InfoStructure
  • Evolution of a Service Oriented Grid
    for eGovernment
  • Third Emerging Components Conference
  • March 24, 2004 at FOSE
  • Washington, D.C.

Peter Gallagher

Public InfoStructure Evolution of a
Service Oriented Grid
  • What is the Grid
  • Interoperability Driving Force in Public
    InfoStructure
  • Example of Federal investment, standards and Open
    Source EZ Reusable Objects (EZRO)
  • InfoStructure People, Processes working with
    Technology - or - Systems that support
    interaction between people and computers

3
Grid Checklist / Issues
  • Coordinates resources that are not subject to
    centralized control..
  • Uses standard, open, general-purpose protocols
    and interfaces
  • Delivers nontrivial qualities of service
  • Broader than strictly computational grid rather
    coordinated use of resources to deliver service
  • Service distribution not centralization
  • Resource Sharing not just Re-use
  • What is the Grid? Ian Foster, Argonne
    National Lab/U. of Chicago, July 20, 2002

Perspective IT Solutions Provider
  • Design, develop, manage and operate custom
    eGovernment solutions
  • US Federal, UN, and private consulting firms
  • DoS, DoL, GSA, USAID, FDA, HHS, etc.
  • Small business in a hyper-competitive IT market
  • 40 Staff/5 mil. Revenue
  • Over 10 years experience in Federal IT market

5
Interoperability and Governmental Coopetition
- Ideal to Promote the Grid
  • Horizontal Federal, State and Local
  • Vertical Health, safety, security, etc.
  • Unlike the private sector no one is injured by
    sharing knowledge
  • Not competition but coopetition
  • Ideal environment for shared investments in
    public infostructure need flexible mechanism
  • Share not just data/standards but implementing
    code for Grid enabling Web services/components

EZ Reusable Objects (EZRO) Department of Labor
Workforce Connections
  • SCORM (Shareable Content Object Reference Model)
  • Standard for eLearning content authoring (see
    http//adlnet.org/)
  • SCORM-compliant software evolved over two years
    into production software powering 100 sites
    including high-volume DOT-GOV sites
  • Usable accessibility Section 508
    (disabilityinfo.gov)
  • OSS technology
  • Python, Zope, Apache, Debian GNU/Linux, etc.
  • Also runs in Windows
  • Released via General Public License (GPL) same
    as license as used by the popular Linux operating
    system

Open Source Software (OSS) Benefits for Small
IT Services Provider
  • Discourages Vendor Lock-in Small business
    poses less risk to Agency hence easier to buy
    services/products
  • Bidding Lower cost initially and TCO
  • Outsourcing - less complex pricing re.
    licensing/upgrades
  • Complete and simple ownership/transfer
  • Intra-agency Federal
  • Inter-governmental Federal/State/Local and
    International
  • Public/Commercial
  • Replication Costs Lower / Massive Efficiency
    Gains
  • Published approaches/Standards Based by
    definition cheaper experimentation by vendors
  • New model! Good for small business / competition

15
What made EZRO Possible / Grid?
  • Standards SCORM / many internet protocols
  • Low cost open source software to build on (Zope,
    Apache, Python, Linux, etc.)
  • Investment s mostly Federal, several Agencies,
    and private (devis)
  • License vehicle to clarify commercial usage
  • Someday move from re-use to resource sharing for
    content/elearning presented just-in-time and via
    a services Grid Holy Grail?

16
Closing Issues
  • Agreements in place
  • Mechanism (TCD/IP, HTTP, etc.) - YES
  • Syntax (XML, EDI, etc.) - YES
  • Semantics (Meaning Identification) Always
    Difficult
  • How can OSS and Federal investment promote
    services grid and ensure interoperability?
  • Think differently about our systems and
    distributed computing
  • Public infostructure is inevitable
