Currently there is no way to query the state of VM-based resources managed by Vcycle and Vac. GridPP is prototyping publishing the state of tenancies and VMs on OpenStack etc which are managed by Vcycle, using the JSON representation of GLUE 2.0. This talk will outline how Vcycle’s concepts of spaces and machinetypes have been mapped to GLUE 2.0 ComputingServices, ComputingShares etc, and represented in JSON documents.
