When deploying a new VMware Cloud Foundation (VCF) environment, the VMware Cloud Builder Virtual Appliance must be deployed on an ESXi host, and it can be placed on either an ESXi host designated for the Management Domain or on a separate ESXi host that is not yet assigned to any specific domain. These options allow for flexibility in the initial deployment process and ensure the Cloud Builder appliance is hosted within a compatible and stable environment.
Other options, such as deploying Cloud Builder on systems running non-ESXi platforms like VMware Workstation, VMware Fusion, or other operating systems (e.g., Windows or Red Hat Enterprise Linux), are not supported for deploying Cloud Builder in VCF.
