1 May 9, 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 May 9, 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 May 9, PlanetLab Installation Comparison DSMTAppma nager PLuSHStorkPldepl oy CoMonroll your own Node selection Sliver allocation Instance installation Integrated with resource allocation Automatic re-installation Decentralized Monitoring

4 May 9, 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 May 9, 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 May 9, 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 refresh=3600 Run monitor to view PsEPR status events

7 May 9, DSMT in Operation Your Application PsEPR Deployment-agent Sliver manager Container manager dsmtc manage –slice my_slice dsmtc setplan –plan limit count=100 Application supervisor STORK SWORD Bellagio CoMon PLC

8 May 9, DSMT Toolkit Version 1.0 Infrastructure PsEPR Service –Event message overlay »loosely coupled, publish/subscribe’ish –http://psepr.org/ for documentation and statushttp://psepr.org/ DSMT Service –Container monitoring –Resource (Container) Planner –Container-Mgr –Deployment-agent

9 May 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 May 9, Join the Testing Crew Release in second week of May
