NDB deployments on NC2 use overlay networking created with Nutanix Flow Virtual Networking. Consequently, an appropriate Flow overlay subnet must be created for NDB and the database server VMs that it will manage. A floating IP address must also be created or assigned to the NDB VM so that the NDB interface and services are reachable through the cloud networking environment. A Flow underlay subnet is not the supported network type for this deployment. Although an NC2 environment ultimately operates within AWS networking infrastructure, creating a native AWS VPC is not the NDB-specific deployment step requested by the question. Nutanix’s NC2 networking documentation identifies Flow-created overlay networks, while the Flow integration guidance describes assigning a floating IP address to the NDB VM.
