Term Description
availability zone Collection of infrastructure components. Each availability zone is isolated from other availability zones to prevent the propagation of failure or outage across the data center.
Application virtual networks (AVNs)

Virtual networks backed by overlay segments using the encapsulation protocol of NSX-T. Virtual Networks use a single IP network address space, to span across data centers.

bring-up Initial configuration of a newly deployed VMware Cloud Foundation system. During the bring-up process, the management domain is created and the VMware Cloud Foundation software stack is deployed on the management domain.
cluster image Precise description of the software, components, vendor add-ons, and firmware to run on a host. With this new functionality, you set up a single image and apply it to all hosts in a cluster, thus ensuring cluster-wide host image homogeneity.
commission host Adding a host to VMware Cloud Foundation inventory. The host remains in the free pool until it is assigned to a workload domain.
composability Ability to dynamically configure servers to meet the needs of your workloads without physically moving any hardware components. You bind disaggregated hardware components (compute, network, storage, and offload components) together to create a logical system based on the needs of your applications.
dirty host A host that has been removed from a cluster in a workload domain. A dirty host cannot be assigned to another workload domain until it is decommissioned, reimaged, and commissioned again.
decommission host Remove an unassigned host from the VMware Cloud Foundation inventory. SDDC Manager does not manage decommissioned hosts.
Edge cluster A logical grouping of NSX-T Data Center Edge nodes. These nodes run on a vSphere cluster, and provide north-south routing and network services for the management and VI workload domains.
free pool Hosts in the VMware Cloud Foundation inventory that are not assigned to a workload domain
host An imaged server.
inventory Logical and physical entities managed by VMware Cloud Foundation.
Kubernetes - Workload Management With Kubernetes - Workload Management, you can deploy and operate the compute, networking, and storage infrastructure for vSphere with Tanzu workloads. A vSphere with Tanzu workload is an application with containers running inside vSphere pods, regular VMs, or Tanzu Kubernetes clusters.
Lifecycle Manager (LCM) Automates patching and upgrading of the software stack.
management domain Cluster of physical hosts that contains the management component VMs
network pool Automatically assigns static IP addresses to vSAN and vMotion vmkernel ports so that you don't need to enter IP addresses manually when creating a VI workload domain or adding a host or cluster to a workload domain.
patch update bundle Contains bits to update the appropriate Cloud Foundation software components in your management or VI workload domain.
region Regions are geographically separate locations, that can provide disaster recovery between data centers. Latency between them must be 150 ms or lower. A region can consist of one or more VMware Cloud Foundation instances.
SDDC Manager Software component that provisions, manages, and monitors the logical and physical resources of a VMware Cloud Foundation system.
SDDC Manager VM Virtual machine (VM) that contains the SDDC Manager services and a shell from which command line tools can be run. This VM exposes the SDDC Manager UI.
server Bare metal server in a physical rack. After imaging, it is referred to as a host.
unassigned host Host in the free pool that does not belong to a workload domain.
vSphere Lifecycle Manager (vLCM) A vCenter service, which is now integrated with Cloud Foundation, that enables centralized and simplified lifecycle management of ESXi hosts.
workload domain A policy based resource container with specific availability and performance attributes that combines vSphere, storage (vSAN, NFS, or VMFS on FC) and networking (NSX-T) into a single consumable entity. A workload domain can be created, expanded, and deleted as part of the SDDC lifecycle operations. It can contain cluster(s) of physical hosts with a corresponding vCenter to manage them. The vCenter for a workload domain physically lives in the management domain.
