Workspace service: is web services based and provides security with the GSI
authentication and authorization. Currently, Nimbus supports two frontends:
Amazon EC2 and WSRF.
• Workspace control: is responsible for controlling VM instances, managing and
reconstructing images, integrating a VM to the network and assigning IP and
MAC addresses. The workspace control tools operate with the Xen hypervisor
and can also operate with KVM5.
• Workspace resource management: is an open source solution to manage
different VMs, but can be replaced by other technologies such as OpenNebula.
• Workspace pilot: is responsible for providing virtualization with few changes in
cluster operation. This component handles signals and has administration tools.
