Overview
This document describes how to manage data centers, clusters, and hosts in a ZStack Cube Virtualization Edition environment, and how to maintain host status and host hardware devices.
Data centers, clusters, and hosts are core objects for organizing and providing virtualization resources in ZStack Cube Virtualization Edition. A data center groups resources, a cluster pools host compute capacity, and a host provides the physical compute resources required to run virtual machines.
| Object | Description |
|---|---|
| Data Center | A data center is the top-level resource namespace in ZStack Cube Virtualization Edition. It organizes resources such as clusters, hosts, storage, networks, and virtual machines. |
| Cluster | A cluster is a collection of hosts in a data center. It pools compute capacity and hosts virtual machines. |
| Host | A host is a physical compute node managed by ZStack Cube Virtualization Edition. It provides CPU, memory, hardware devices, and network connectivity for virtual machines. |
