Edge Services
  • Services executing on the edge of the public and
    private network

Edge Service Requirements
  • Configuration Issues
  • The configuration requirements can vary widely
    per Edge Service per community.
  • We need an easy way to upgrade Edge Services
  • Alternative Edge Services
  • Resource allocation issues
  • Flexibility in dynamically managing resource
    assignments as load demands fluctuate
  • Fair usage between communities
  • Incentives

4
Virtual Machines
  • Excellent isolation, security, fine-grain
    forensics
  • Promising enforcement properties
  • More control to the site great recoverability
  • Flexible configuration
  • The ability to serialize and migrate
  • Modern implementation are fast

5
Virtual Workspaces
  • Virtual Workspaces environments that can be made
    available dynamically on the Grid
  • Different possible implementations
  • Workspace Service
  • Enables secure deployment and management of a
    workspace within a trusted computing base
  • Authentication and authorization
  • Deployment configuration
  • Resource allocation enforcement
  • Workspace deployment meta-data image
  • More information and technology preview download
    available at http//workspace.globus.org

ESF Project
  • Phase 1 objective create a proof-of-concept
    dynamic deployment of Edge Services
  • Progress
  • Implement and release the Workspace Service
  • Bubbly test static deployment and test of a real
    Edge Service on a production site
  • Dynamic deployment of an Edge Service and
    integration into OSG infrastructure
  • Configuring more testbeds
  • Deploying and testing more Edge Services

19
Testbed Images
  • Testbed
  • SDSC (Abhishek)
  • OSG production site, 150 worker nodes
  • Intel 2.6, 4GB, RAID device, Xen 2.0.7
  • FNAL (Burt)
  • Xeon 3.2, 4GB, RAID device, Xen 2.0.7
  • UC (Rob, Borja)
  • TeraPort, Xen 3
  • ANL, PIOCON coming online
  • Images
  • SDSC SL3.0.3, FC4, CentOS4.1
  • FNAL SL3.0.3, SL4, LTS 3, LTS 4
  • Edge Services
  • ATLAS mysql-gsi db built by the DASH project

Summary
  • Growing ESF testbed
  • Xen capabilities / ESF requirements
  • Installation woes getting worked out
  • Growing library of images with useful
    configurations
  • Growing infrastructure
