The Ubuntu Enterprise Cloud documentation uses terminology that might be unfamiliar to some readers. This page is intended to provide a glossary of such terms and acronyms.
- Cloud - A federated set of physical machines that offer computing resources through virtual machines, provisioned and recollected dynamically.
- Cloud Controller (CLC) - Eucalyptus component that provides the web UI (an https server on port 8443), and implements the Amazon EC2 API. There should be only one Cloud Controller in an installation of UEC. This service is provided by the Ubuntu eucalyptus-cloud package.
- Cluster - A collection of nodes, associated with a Cluster Controller. There can be more than one Cluster in an installation of UEC. Clusters are sometimes physically separate sets of nodes. (e.g. floor1, floor2, floor2).
- Cluster Controller (CC) - Eucalyptus component that manages collections of node resources. This service is provided by the Ubuntu eucalyptus-cc package.
- EBS - Elastic Block Storage. http://aws.amazon.com/ebs/
