Disclaimer • These slides have been drafted based on the current version of the EGI Blueprint proposal (v1.2, 25 June 2008). • The purpose of this blueprint is to assess a possible model for the future sustainable grid infrastructure in Europe. • The aim of these slides is to support the discussions in the EGI Geneva Workshop (30 June 2008). • The EGI_DS project will modify this draft blueprint on the basis of feedback provided. EGI Operations and Security
Outline • Players • Activities: EGI.org critical services and NGI international tasks • Funding • EGI Operations Model • Effort • Summary EGI Operations and Security
EGI Operations and Security Players: EGI.org • EGI.org: • coordination of operations and security across countries • central user support • operation/maintenance of central operational tools and services EGI Operations and Security
EGI Operations and Security Players: NGIs • NGIs are expected to: • operate secure Grid infrastructures in the countries • coordinate Grid operations in the countries • collaborate to the definition of common operational procedures, policies, standards/specifications • adhere to standards/specifications to ensure interoperability • support users and operational problems EGI Operations and Security
Federation of NGIs • Operation of the European Grid infrastructure is currently guaranteed by the Regional Operations Centres (ROCs) – one ROC for several countries (NGIs) or corresponding to a single large NGI • Increasing push towards increasing responsibility and autonomy of the NGIs, but federation continues to be a viable model in EGI for economy of scale EGI Operations and Security
Outline • Players • Activities: EGI.org critical services and NGI international tasks • Funding • EGI Operations Model • Effort • Summary EGI Operations and Security
EGI.org Critical Services • Mandatory services needed to ensure: • inter-domain interoperation in the pan-European infrastructure, i.e. to keep a consistent operational model across European countries • ease of access and effective usage of the infrastructure by international user communities • can be delegated to one or more NGIs or other organizations as deemed necessary: many critical services already under the responsibility of many Regional Operations Centres in EGEE • EGI.org Operational Unit will be responsible of: • coordination • running those critical services for which central operation will be decided (list to be defined) EGI Operations and Security
NGI International Tasks • technical services under the responsibility of the NGI which are needed • to support international user communities • to ensure cooperation with EGI.org and other NGIs • to allow the integration, operation and sharing of NGI resources at pan-European and international level, as adherence to common policies and specifications/standards is highly needed in a distributed environment • Note: NGI tasks to support local user communities and to satisfy local needs, areout of the scope of EGI EGI Operations and Security

Funding • EGI.org critical services: • Initially fully funded by the EC • after transition also sustained by the NGIs (for example via service charges) • EGI.org critical services are a bundle which must be provided in year one of EGI • NGI international tasks: • funding of the NGI local infrastructure including national IT resources and user communities, and NGI management, is a responsibility of the NGI • EC and NGI co-funding to promote the integration of NGIs resources into the European e-Infrastructure • NGI funding: national funding body, fee-for-service contracts, ...

EGI Operations Model (1/2) • Aims • Autonomy for NGIs using a common infrastructure for local and international work for greater efficiency • Sustainability • Subsidiarity: do things at as local a level as possible (EGI.org pulls things together) • Increased reliability through pushing responsibility down to sites • Preserving current scalability in presence of more middleware stacks to be supported, more non-EGEE Grids integrated, ... EGI Operations and Security
EGI Operations Model (2/2) • Risks • Autonomy leads to diversity (different procedures that don't interface across national boundaries) • More staff required as we lose the economies of scale of the centralised model • Insufficient effort in EGI.org spec leads to ineffective coordination. • Mitigation • Middleware interoperability via common interfaces • common solutions and procedures for efficiency • Federation of NGIs • Agreement on sharing of EGI.org responsibilities with NGIs EGI Operations and Security
EGI Operations Model and EGEE III • EGI model needs to be consistent with the evolution trend in EGEE III • EGEE-III contains already the implementation of structural changes required to allow for a seamless transition from the current project-based EGEE model to a stable EGI model based on NGIs • preparation work for a smooth transition already started in EGEE III EGI Operations and Security
Outline • Players • Activities: EGI.org critical services and NGI international tasks • Funding • EGI Operations Model • Effort • Summary EGI Operations and Security
Resource estimates • Effort estimated to cope with the EGI transition phase • Efficiency after a few years might reduce the staff requirement • we expect this to be matched by the requirement for new services to meet the evolving requirements of new communities. • Estimates do not take into account: • activities which require tool development work (monitoring and accounting tools, Grid service management tools, etc.), which will be part of the Middleware Function • additional tasks directly related with the Middleware Function (i.e. the deployment and management of experimental and pre-production Grid testbeds) • these are still expected to be run under the responsibility of operations staff EGI Operations and Security
EGI.org Mandatory Services • Three cathegories: • Operation of tools and services • User Support • Coordination EGI Operations and Security

NGI International Tasks (2/2) EGI Operations and Security
Catch-all services for NGIs • NGIs free to choose the most suitable provisioning model for the requested international tasks: • under the responsibility of the NGI (or a federation of NGIs) • devolution to a third party • service purchased from EGI.org (catch-all) • to facilitate NGIs, especially during the transition phase • economy of scale: number of FTEs needed by EGI.org to run catch-all services scales well with the number of NGIs requesting it EGI Operations and Security
NGI Resource Estimates • resource estimation carried out during the preparation phase of EGEE III for the SA1 activity (Operations) • Different levels of complexity of NGIs and ROCs • Large ROC: 16 FTEs (5 Grid Management, 6.5 Operations and Support, 3.5 Support to VOs, Users and Applications, and 1 Grid Security) • Small ROC: 6 FTEs (2 Grid Management, 2 Operations and Support, 1 Support to VOs, Users, Applications, 1 Grid Security) • sustainability of Asia-Pacific ROC?

Overall NGI Effort EGI Operations and Security
Summary • EGI Operations: a joint effort of NGIs and EGI.org • Funding: • full EC funding for EGI.org critical services, co-funding for NGI international tasks • Effort: • EGI.org: 16 FTE • NGIs: from 200 to 300 FTEs • Increasing autonomy of NGIs is a challenge • transition started in EGEE III EGI Operations and Security
