Service Level Agreements In Virtualised Service Platforms

  1. 1. Service Level Agreements in Virtualised Service Platforms Georgina Gallizo 1 , Roland Kübert 1 , Karsten Oberle 2 , Andreas Menychtas 3 , Kleopatra Konstanteli 3 Presenter: Roland Kübert High Performance Computing Centre Stuttgart University of Stuttgart Germany 1 : High Performance Computing Center Stuttgart, University of Stuttgart 2 : Alcatel-Lucent, Bell Labs, 3 : National Technical University of Athens
  2. 2. Introduction <ul><li>http://irmosproject.eu </li></ul><ul><li>IRMOS is an FP7 project with partners from all over Europe. The project started in February of 2008 and will run for 36 months. </li></ul>
  3. 3. Table of Contents <ul><li>Introduction </li></ul><ul><li>Motivation and problem area </li></ul><ul><li>Research objective </li></ul><ul><li>Research approach and methodology </li></ul><ul><li>Major outcomes and results </li></ul><ul><li>Conclusion and outlook </li></ul>
  4. 4. Motivation, problem area <ul><li>Interactive real-time applications, either for soft or hard real-time, require strong QoS guarantees </li></ul><ul><li>Nowadays, RT is only achievable through distinct hardware and software </li></ul><ul><li>IRMOS strives to combine Service Oriented Infrastructures (SOIs) with real-time applications </li></ul>Graphic from http://www.irmosproject.eu/
  5. 5. Research Objectives <ul><li>How to combine RT and SOI (Virtualisation) </li></ul><ul><li>SLA Management Framework covering the complete value chain </li></ul><ul><li>Mapping of high-level application parameters to low-level resource provision attributes </li></ul><ul><li>Validation through application scenarios </li></ul>
  6. 6. Research approach, M ethodology <ul><li>Using applications as an example for the requirements </li></ul><ul><li>Virtual and augmented reality as a scenario using the COVISE (COllaborative VIsualization and Simulation Environment) software </li></ul><ul><li>Identification of actors in the value chain (IRMOS, ISONI, …) for the scenario </li></ul><ul><li>Identification of use cases for the scenario </li></ul>
  7. 7. Major O utcomes /Results <ul><li>One SLA is not enough: identified different types of SLAs </li></ul><ul><li>Each SLA corresponds to one contact point between actors in the value chain </li></ul>IRMOS Project, D7.2.1 Initial version of Path Manager: Architecture, ALUD and other partners, May 2009
  8. 8. Major Outcomes / Results II <ul><li>Union of SOI and RT offers major business benefits </li></ul><ul><li>Usability for other scenarios, e.g. where </li></ul><ul><ul><li>massive collaboration with real-time constraints is expected, such as e-learning applications with high numbers of users interacting with the application and with other users; </li></ul></ul><ul><ul><li>high volumes of data need to be processed, supporting real-time interaction with end users, such as film post-production applications.   </li></ul></ul>
  9. 9. Conclusion and outlook <ul><li>Distinct contracts depending on the actors (A-SLA, T-SLA) necessary </li></ul><ul><li>Enhancing SOI with RT is a novel approach </li></ul><ul><li>It‘s challenging but possible </li></ul><ul><li>Implementation is performed now for the first demonstrator (finished in Feb. 2010) </li></ul>
  10. 10. Questions? <ul><li>? </li></ul>
