Template	A reusable VM image used to deploy new VMs quickly.
ISO	A bootable installation image that can be mounted to a VM.
Appliance	A pre-packaged image deployed as a ready-to-run VM.
Image Library	The collection of templates, ISOs and appliances available to deploy.
vCPU	A virtual CPU presented to a VM.
Compute pool	A pool of physical CPU and memory capacity that quotas draw from.

Term	Definition
Network (VNet)	A virtual network that provides isolated connectivity for VMs.
VLAN	A tagged layer-2 segment (ID 1–4094); created under Networks (root only).
Subnet	An address range (CIDR) within a network.
Firewall	A virtual firewall protecting a network, with rules, NAT, routing and DHCP.
SNAT / DNAT	Source / destination network address translation rules on a firewall.
OSPF	A dynamic routing protocol configurable on a firewall.
VPN	A WireGuard VPN gateway providing secure remote connectivity.
CIDR	Notation for an IP range, e.g. 10.0.0.0/24.

Term	Definition
Backup policy	A schedule and retention rule set applied to VMs.
Backup job	A single execution of a backup policy.
Restore point	A recoverable snapshot produced by a backup job.
Proxmox Backup Server (PBS)	The backup server a storage pool is backed by so it can hold VM backups.

Term	Definition
Account / Tenant	An organisational unit that owns resources; a tenant is a child account.
Root account	The top-level account with platform-wide administration.
Account context	The account you are currently acting within; root users can switch down into a tenant.
Quota	A per-tenant allocation of compute or storage capacity (0 or unset = unlimited).
Guarantee vs Max	The reserved amount vs the burstable ceiling for a quota dimension.
PAYG	Pay-as-you-go: a dimension billed on usage rather than a fixed allocation.
Shared resources	Networks, ISOs, appliances or templates assigned from a parent to a tenant.
Resource group	A tag-based grouping of resources across compute, networking and data protection.
Tag	A key/value label attached to resources for grouping and filtering.
User group	A collection of users that roles can be assigned to together.
Role	A named set of permissions assigned to users or user groups.
Permission	An action-based access key in the form category.module.action — see Permissions reference (click here).
RBAC	Role-based access control — the model governing who can do what.

Term	Definition
Cluster	A managed group of hypervisor nodes providing compute and storage.
Node	A single physical host within a cluster.
Physical NIC	A physical network interface on a node, mapped during cluster setup.
Syslog destination	A remote target that platform logs are forwarded to.
Audit log	The platform-wide record of administrative events.
Task	An asynchronous unit of work queued by the API and executed by a worker.
Alert	A read-only, root-cause finding raised by the ITSM engine — see Alerts (click here).
