Virtual Domain (VDOM) and Administrative Domain (ADOM)

A Virtual Domain (VDOM) is a complete FortiADC instance that runs on the FortiADC platform. VDOM configuration objects contain all of the system and feature configuration options of a full FortiADC instance and can be used to divide a FortiADC into two or more virtual units that function independently, allowing it to support multi-tennant deployments.

The VDOM feature supports two Virtual Domain Modes that allow the VDOMs to function independently with its own networking or as Administrative Domains (ADOMs) with shared networking between all ADOMs. When the VDOM is in the Independent Network mode, you can provision an administrator account with privileges to access and manage only their assigned VDOM. The VDOM user can then configure their VDOM as desired untethered to other VDOMs. Alternatively, when the VDOM is in Share Network mode, it functions as an ADOM that shares the same networking interfaces and routing between all the ADOMs. The ADOM functionality enables the administrator to constrain access privileges to a subset of server load-balancing servers by defaulting all interface settings to the root ADOM.
