Concepts and Terminology
- Infrastructure: The compute and storage resources in a cloud or infrastructure service (AWS, etc) that an NDS Labs cluster runs on. The NDS Labs reference architecture is OpenStack.
- Site: A site is an administrative organization that provides resources to and operates one or more NDSLabs clusters.
- Cluster/NDS Labs cluster: The NDS Labs software platform that runs on the infrastructure.
- Project/Namespace: An isolated, named environment within the cluster that contains a set of services that are managed and operated independently of other projects. Projects typically implement the equivalent of a "website".
- Administrator: An authenticated person that manages and operates a part of the system.
