2Public 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
3Grid 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
4Perspective 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
5Interoperability 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
6EZ 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

14Open 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
15What 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?
16Closing 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
