Nimbus

DEPRECATED: The most recent version is Nimbus TP2.2

Version TP1.2.2 - Virtual Machines Technology Preview 1.2.2

This is a technology preview of the virtual machine based Workspace Service. The workspace service provides a gateway to a set of resources configured with the Xen (2.0.7 or 3.0.x) implementation of virtual machines.

The infrastructure is composed of:

1. The Workspace Factory Service implemented for the GT4 Java container that allows a grid client to deploy a Xen-based workspace (described by workspace metadata and a Xen image) according to a deployment request specifying resource allocation and length of deployment.

2. The Workspace Service implemented for the GT4 Java container that allows a Grid client to manage a workspace by starting, stopping, pausing, or destroying it.

Workspace metadata and the interfaces for the two Grid Services are discussed in the interfaces section. The Administrator's Guide discusses the installation of the service and the required backend component.

A discussion of the available plugins and an authorization overview is in this section.

The sample service client is distributed with several sample metadata files, deployment requests, and sample client invocations. Follow the User Guide through several sample invocations with conceptual explanations.

You can download the software from the downloads page.
