EGEE Partners

• 71 leading institutions in 27 countries, federated in regional Grids

• 32 M Euros EU funding (2004-5), O(100 M) total budget

• Aiming for a combined capacity of over 20’000 CPUs (one of the largest international Grid infrastructures ever assembled)

• ~ 300 dedicated staff

OMIISC, London 3

EGEE Activities

• 48 % service activities (Grid Operations, Support and Management, Network Resource Provision)

• 24 % middleware re-engineering (Quality Assurance, Security, Network Services Development)

• 28 % networking (Management, Dissemination and Outreach, User Training and Education, Application Identification and Support, Policy and International Cooperation)

Emphasis in EGEE is on operating a productiongrid and supporting the end-users

Deployment of Applications

Pilot New

• Pilot applications– High Energy Physics– Biomed applications

• Generic applications –Deployment under way– Computational Chemistry– Earth science research – EGEODE: first industrial application– Astrophysics

• With interest from – Hydrology– Seismology – Grid search engines – Stock market simulators– Digital video etc.

EGEE Grid strategy

• Continue to deploy and operate a production oriented Grid infrastructure application agnostic

• Validation performed by Biomedical and HEP applications

• Interoperability with other major Grid international infrastructures (OSG in the US, NorduGrid etc.)

• Supporting new Grid infrastructure consortia being created in Baltic countries, Mediterraneum bacin, Latino America and Asia (Japan, China, Taiwan, Korea, Singapore…)

• Supporting new Virtual Organisations (implement the EGEE “virtuous cycle”)

• Developing a long term sustainability plan

EGEE Standards Activities

• EGEE is active in several standardisation and forum bodies (e.g. IETF, OASIS, GGF, OMII)

• Interesting standards we are currently tracking includeWS-Security, WS-Addressing, WS-Notification, WS-Agreement, WSRF, SRM, GMA, GFS, JSDLWS-Trust, SAML, XACML…

• EGEE is mainly a consumer (user) of basic standards (e.g. WS-*)

• Actively contributing to best practices (e.g. SRM) which may evolve into standards

EGEE and eIRG

• EGEE strongly supports the work of the eInfrastructures Reflection Group (eIRG), which is a forum for practitioners and policymakers exchange information about state of the art of the technology and policy-level issues that need to be solved. The support consists of:– Editorial support (Fotis Karayannis)– "Virtual Office" support at CERN– Active involvement in the startup phases of each White Paper

project together with the eIRG steering committee and EU representative.

• eIRG is exploring a closer relation to ESFRI• http://www.e-irg.org/

EGEE Concertation Activities

• EGEE participated in the European Grid Technology Days 2004, an IST-FP6 Grid Projects Launch and Concertation event in Brussels, Sept. 2004http://www.nextgrid.org/events/

• EGEE hosted the First Concertation Meeting on eInfrastructures with participation from both Grid research and infrastructure project groupsin The Hague, The Netherlands, Nov. 2004http://public.eu-egee.org/concertation/

Web Service Standards

• The promise from Web-Services is huge – e.g.– Seamless integration between heterogeneous systems over the

Internet– Self-described API and automatic client generation (multi-

languages)– Strong model for rich and clear semantics (security, policy, etc)

• Strong support from the industry (e.g. Microsoft, IBM), which in turn promises the development of good tools

• Few Web-Service standards are stable and have production quality tooling support for a variety of languages

• Web-Services are still to be proven as a viable solution in a production quality environment

gLite and Web-Services

• EGEE is about production, not R&D – EGEE has to deploy production quality middleware now

• We believe that Web-Services will be a key technology for gLite (EGEE Grid middleware)

• Since standards haven’t solidified yet, EGEE is however taking a cautious approach towards WS-*

• We are committed to WS-I (Basic Profile) compliance to maximise interoperability

• More WS-* standards will be used as their maturity is demonstrated

OMIISC, London 12


INFSO-RI-508833

gLite and Web-Services roadmap

• gLite v1 (expected in March 2005) will have services partially exposing Web-Service interfaces– Data management– Logging and Bookkeeping– CE (partially)

• More services will expose WS interfaces in future releases

• Current security solution is based on TLS (SOAP over HTTPS)– due to performance reasons– due to lack of support (e.g. no good WS-Security for Perl clients)

• We are actively pursuing MLS based solutions (e.g. WS-Security)

Summary

• EGEE considers standards to be paramount– Interoperability (incl. with other Grid infrastructures)– Industry support

• EGEE is collaborating with several other Grid related projects on standards and best practices (e.g. Condor, Globus, OMII)

• EGEE identifies “gaps” for which no standards exist(e.g. delegation and application interaction with infrastructure components/firewalls)

• EGEE is, in particular, tracking progress of WS-* standards and related tooling
