'''Nimbus''' is an [[open-source]]a toolkit that, once installed on a [[Cluster (computing)|cluster]], provides an [[Infrastructureinfrastructure as a Serviceservice]] [[cloud computing|cloud]] to its client via [[Web Services Resource Framework|WSRF]]-based or [[Amazon Elastic Compute Cloud|Amazon EC2]] [[Web Services Description Language|WSDL]] [[web service]] [[Application programming interface|APIs]]. Nimbus is [[free and open-source software]], subject to the requirements of the [[Apache License]], version 2.
*Nimbus Allowssupports both the [[hypervisor]]s [[Xen]] and [[Kernel-based Virtual Machine|KVM]] and virtual machine schedulers [[Portable Batch System]] and [[Oracle Grid Engine]]. It allows deployment of self-configured virtual clusters via contextualization .<ref> [[Kate Keahey | Keahey, K. ]], Freeman, T. (2008).
