  1. Distributed Services Management Toolkit Subu Iyer, Dejan Milojicic, Vanish Talwar, and Sandro Rafaeli Robert Adams and Paul Brett PlanetLab User’s Meeting May 1, 2005

  2. Distributed Services Management Toolkit • The Problem • we have: cool virtual machines, cool locations in the Internet, cool resource allocation systems, cool distribution systems • no framework for integrating their use • The Solution: DSMT • Installation and monitoring system • Framework for managed resource use • Node selection and control • Plug-ins for interesting research areas: • distributed application management, • resource negotiation • container installation

  3. PlanetLab Installation Comparison

  4. DSMT • Create a framework for distributed application operation • Selection of resources • Allocation and provisioning of resources • Installation and running of application instances • Monitoring of application operation • Base services • Event messaging systems (PsEPR) • Generalized ‘application manager’

  5. DSMT Goals • Wrap services with existing services • Structure which includes resources allocation, resource negotiation, PLC interface, … • Solves “first problems” • Allocation of PlanetLab nodes and slivers • Installation of application components • Monitoring application operation • Collection of results data • Termination • Targeted at new PlanetLab users

  6. Distributed Service Deployment and Monitoring • PI creates managed slice • dsmtc create –slice my_slice –user PLuser • Application writer makes application installable • rpmgen –file ball.tar … • dsmtc depot put rpmfile • dsmtc setagent –agent deployment-agent • Slice user specifies destinations • dsmtc setplan –base sword –plan myplan query=@sword.xml refresh=3600 • Run monitor to view PsEPR status events

  7. DSMT in Operation dsmtc manage –slice my_slice dsmtc setplan –plan limit count=100 Your Application Application supervisor PsEPR Deployment-agent Container manager Sliver manager CoMon STORK SWORD PLC Bellagio

  8. DSMT Toolkit Version 1.0 Infrastructure • PsEPR Service • Event message overlay • loosely coupled, publish/subscribe’ish • http://psepr.org/ for documentation and status • DSMT Service • Container monitoring • Resource (Container) Planner • Container-Mgr • Deployment-agent

  9. DSMT Evolution Plans • Version 1: May • Solve PlanetLab first app problem • sample solution based on YUM and centralized service planner • Version 2: September • Long term, complex services • Success = we win 3 existing services • Web Services based (GGF CDDLM standard) application specification • Address service dependencies, service-based APIs • Version 3: December • models and adaptation • open APIs for service composition • Version 4: • distributed models

  10. Join the Testing Crew • http://dsmt.org/ • Release in second week of May
