15 May 2015 JA-SIG Winter Conference 2002 Orlando, Florida Michael R Gettes Principal Technologist Georgetown University Michael R Gettes Principal Technologist Georgetown University National Science Foundation Middleware Initiative (NMI)

2 NSF Middleware Initiative Purpose To design, develop, deploy and support a set of reusable, expandable set of middleware functions and services that benefit applications in a networked environment

3 NMI Organization GRIDS Center – ISI, NCSA, U Chicago, UCSD & U Wisconsin EDIT Team (Enterprise and Desktop Integration Technologies) –EDUCAUSE, Internet2 & SURA Core NMI Team Grants for R & D Year grants Year grants

4 Experimental Software & research applications Middleware deployment Consensus - disciplines - communities - industries Early Implementations - GRID services, directories, authentication, etc MiddlewareTestbeds - experimental, Beta, scaling & “hardening” Early Adopters Dissemination & Support Research & Education NMI Process

5 First Deliverables: NMI Release 1 Software (Globus, Condor, Network Weather Service, KX.509, CPM, Pubcookie) Object Classes (eduPerson, eduOrg, commObject) White Papers (Shibboleth, video directories, etc) Best Practices (Directories, LDAP) Policies (campus certificates, account management) Services (certificate profile registry)

6 GRIDS Center, Part of the NSF Middleware Initiative One of two NMI teams, the GRIDS Center (Grid Research, Integration, Development & Support) In late 2001, GRIDS created to: Define, develop, deploy, and support an integrated national middleware infrastructure for 21 st Century S&E Create robust, tested, packaged, & documented middleware for S&E, including large NSF projects (e.g., NEES, GriPhyN, TeraGrid) Work with middleware research community to evolve architecture & integrate other components Provide dedicated operations capability for 24x7 support and monitoring of Grid infrastructure

7 Elements of Grid Computing Resource sharing as a fundamental pursuit Computers, storage, sensors, networks Sharing is always conditional, based on issues of security, trust, policy, negotiation, payment, etc. Coordinated problem solving Beyond client-server: distributed data analysis, computation, collaboration, etc. Dynamic, multi-institutional “virtual organizations” Community overlays on classic org structures Large or small, static or dynamic

8 Grid-Oriented Projects in eScience

9 Grid Applications Science portals Help scientists overcome steep learning curves of installing and using new software Distributed computing High-speed workstations and networks as aggregated computational resources Large-scale data analysis Computer-in-the-loop instrumentation Grids permit quasi-real-time analysis of data from telescopes, synchrotrons, and electron microscopes Collaborative work Grids enable collaborative problem formulation, data analysis, and discussion

11 Size distribution of galaxy clusters? Sloan Digital Sky Survey Analysis Galaxy cluster size distribution Chimera Virtual Data System + iVDGL Data Grid (many CPUs)

12 Grids and Industry Grid computing has much in common with major industrial thrusts to decentralize (e.g., B2B, P2P, ASP, etc.) Sharing issues are not adequately addressed by existing technologies Companies like IBM, Platform Computing and Microsoft are now substantively involved with the open-source Grid community (e.g., OGSA, which combines Web services and Grid services)

13 NMI-EDIT: Goals Much as at the network layer, create a ubiquitous common, persistent and robust core middleware infrastructure for the R&E community In support of inter-institutional and inter-realm collaborations, provide tools and services (e.g. registries, bridge PKI components, root directories) as required

14 A Map of Middleware Land

15 NMI-EDIT: Core Middleware Scope Identity and Identifiers – namespaces, identifier crosswalks, real world levels of assurance Authentication – campus technologies and policies, inter-realm interoperability via PKI, Kerberos Directories – enterprise directory services architectures and tools, standard object classes, inter- realm and registry services Authorization – permissions and access controls, delegation, privacy management Integration Activities – common management tools, use of virtual, federated and hierarchical organizations

16 NMI-EDIT: Organization Overall technical direction set by MACE Middleware Architecture Committee for Education (MACE) Campus IT architects and representatives from Grids and International Communities Directions set via NSF and NMI management team Internet2 Network Planning and Policy Advisory Council PKI and Directory Technical Advisory Boards Internet2 members

17 Sample NMI-EDIT Process (Directories ) MACE-DIR Working Group prioritizes needed materials Subgroups established: revision of basic documents (LDAP Recipe) new best practices in groups and metadirectories standards development for eduPerson 1.5 and eduOrg 1.0 Subgroups work in enhanced IETF approach: scenarios, requirements, architectures, recommended standards stages Working group deliverables announced; input and conference call review/feedback processes start; work groups reconvene as needed Process takes around 4-6 months, depending on product 6-8 people drive the process with schools participating

18 A Few Year-One NMI-EDIT Milestones Sept 1, 2001 – Grant awarded Oct 2001– eduPerson 1.0 finalized; outreach begins with multiple workshops Jan 2002 – HEBCA tested; first CAMP workshop held Feb 2002 – PKI Lite CP/CPS; e-Gov and Management and Leadership Best Practice Awards April 2002 – Shibboleth alpha ships; NMI testbed selected; NIST/NIH PKI workshop May 2002 – NMI release, with eduPerson 1.5, pubcookie, KX.509, groups and metadirectories, video white papers June 2002 – affiliated directories begins; Base CAMP; testbed kickoff July 2002 – Shibboleth alpha v 2 ships; Advanced CAMP August 2002 – LDAP Analyzer testing begins; Shibboleth pilot-sites selected; Work with content providers begins September 2002 – Grant renewed; supplemental grant awarded for outreach; Shibboleth beta ships October NMI Release 2 (see itemized list;
