Overview of ExoGENI Auxiliary Infrastructure

Besides the ORCA actors ExoGENI is supported by a number of additional elements of auxiliary infrastructure. Those include

  • ImageProxy agents on each head node (port 8080) responsible for managing user boot images for virtual machines.
  • ORCA Actor Registry - a global registry of known Orca actors.
  • NDL-OWL/RSpec conversion service - a distributed service responsible for converting between internal ORCA NDL-OWL resource representations and GENI RSpec. This service is hosted in a number of locations and is used transparently by ORCA actors as needed.
