  1. An SLA framework for the GT4 Grid middleware Igor Rosenberg Atos Origin Spain In collaboration with René Heek (HLRS) Ana Juan (Atos Origin)

  2. Motivation, problem area • Recognised problem of assuring a decent Quality of Service (QoS) • Service Level Agreements (SLAs) are probably the most important documents in every business-aware framework –at least they should be. • Existing implementations supporting full SLA management?

  3. Research Objectives • State-of-the-art of SLA frameworks • Discover business needs based on real experiences • Define and implement the missing pieces.

  4. Research approach, Methodology … BE25 Other projects BE2 BE3 BE1 ... • BEinGrid SLA Cluster: • horizontal look at SLA best practices and gap-analysis Middleware 1 Mdw -n Middleware 2

  5. The BEinGRID Methodology • Extract SLA Common Technical Requirements Needs expressed in a given scenario • Define Common Capabilities A functionality which answers this technical need • Define Design Patterns The middleware-agnostic architecture needed to provide this functionality • Define Components Middleware-specific implementations

  6. Major Outcomes/Results • SLA Common Technical Requirements • Common Capabilities • Design Patterns • Components • SLA Template Specification • Publication and Discovery • Negotiation • Optimization of Resource Selection • Monitoring • Evaluation • Re-negotiation • Accounting • SLA Negotiation for GT4 • SLA Optimisation of Resource Selection for GRASP, and for GT4 • SLA Monitoring and Evaluation for GRASP, and for GT4 • SLA Accounting for GRIA and GT4 • Results: • Requirementsforgeneric SLA frameworks • A gap analysis • A set of components • Justifiedbybusinessbenefits

  7. BEinGrid SLA Software components

  8. Global view of the SLA Framework for GT4 v4.0.5 Most BEinGrid capacities are in the SLA framework • Negotiation • Optimisation • Monitoring and Evaluation • Accounting Not yet contemplated Ganglia + MDS included

  9. Gap analysis, comparing various frameworks

  10. Conclusion and outlook • Conclusion • generic technical requirements, common capabilities, design patterns, and components. • Justify a simple architecture based on components: a framework for SLAs for GT4 • Compared it to other existing frameworks • Futurework: • Finishimplementation (November2008?) and validate • Add extra capabilities • Publication and Discovery (marketplace?) • Brokering of templates/negotation • Proposeexamplesfor • Negotiationstrategies • Crisis Handling (changingstrategiesbasedonviolations) • Proveinteroperabilitywithotherframeworks(GRASP, GRIA, UNICORE)

  11.  Game over  Thank you for your attention Any questions?
