3. BREIN in a Nutshell (ubs) Coordinated by Telefonica I+D and technically lead by U. Stuttgart –Best combination for exploitation and research success 16 partners with end-user involvement –Proven complementarity and experience 9.3M (6.6M funding) for 3 years –Challenging results with clear value for money Highly innovative integrating Multiagent and Semantic Web concepts in the grid –a significant step forward High strategic impact thanks to business orientation 4.

5. BREIN in a Nutshell Main Objectives: –Autonomy and Automation Integration of Multiagent, Grid, Semantic Web and Security concepts –Optimisation with respect to the individual business goals and needs –Semantic-Aware Security Enhance security mechanisms with semantic web technology –Reduced Complexity Simplified provisioning and usage of services Increased support for defining and enacting business objectives –Foster existing Results No start from scratch –Public Awareness (visit our really really really empty cool booth in the Exhibitors hall – booth 21) 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 5

7. SLAs in BREIN With the integration of Multiagent and Semantic Web concepts in BREIN, we foresee to enable –discovery on basis of SLA capabilities Customers will be able to define their requirements in their language, whereas the system understands this and is able to perform discover accordingly – a clear understanding of different SLA "languages" (term definitions) Current solutions require in-depth knowledge from the Users about the used SLA language too much efforts, especially for SMEs –mapping between contractual terms and system terms Contractual terms are on a much higher level then system terms. (timetocomplete vs 4CPUs, 2days running…) 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 7

8. SLAs in BREIN (ii) Enable to…. –Dynamically negotiate QoS terms From discrete offer negotiation (one phase) to a multiphase negotiation, with offers and re-offers –Automatically understand the infrastructure capabilities for negotiation purposes Can I or can´t I offer this value (and I need to know this quick) –Optimize negotiation wrt business goals & policies Is it in my interest to negotiate this Service If I agree on an SLA of a high value customer, do I take the risk (intentionally) to violate an already running SLA of another –Compare current SLAs to prioritize (intentionally violation) –Optimize resource usage whilst still meeting the SLA 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 8

9. SLAs in BREIN (iii) Enable to: –Automate the setup of the infrastructure according to the SLA and other requirements In general, BREINs aim is with that to optimize perfomance and resource usage of Service Providers 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 9

11. 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 11 Towards a Discovery and SLA Negotiation Protoype BREIN has the first 12 months a Rapid Prototyping Activity Take what is there No big implementations Only Glue code Goal: Validation of concepts and technologies Prototype Definition Partners: TID, HLRS, CRMPA, ATOS, DATAMAT Collaboration planning Semantically enhanced service discovery Intelligent SLA negotiation Workflow adaption and optimization

12. Capabilities of the Prototype Discovering Services with respect to SLA capabilites Negotiate SLA in a single-round phase Setup a monitoring and evaluation system Monitor system status and convert it into SLA information Evaluate SLA status wrt. agreed SLA Support asynchronous topic-based messaging 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 12

13. 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 13 Towards a Discovery and SLA Negotiation Protoype (ii)

14. What will be used: –SLA Negotiation Components from NextGRID & TrustCoM –WSLA/WS-Agreement –WSRF –Protége-OWL –JADE 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 14 Towards a Discovery and SLA Negotiation Protoype (iii)

15. Conclusion Dynamic SLAs in focus Current State of the Art NOT sufficient Business Grid needs business oriented solutions 8.May 2007 OGF20 – Workshop on Dynamic SLAsPage 15
