Description
A templates of this type are atoms of application logic, and they must be hosted, as they are atomic applications. .
They are expected to have connection point bindings and are used to compose a Network Function, particularly a virtual one.
Nodes of this type are normally concrete, implemented using deployment artifacts.

Capabilities
Types derived from onap.nodes.NetworkFunctionComponent normally extend it by at least one capability of type onap.capabilities.Bindable.
Requirements
| Name | Required | Type | Description |
|---|---|---|---|
| host | yes | tosca.capabilities.Container | A Network Function Component must be hosted. This requirement is normally paired with the host capability of a Compute-typed node. It can also be paired with the host capability of a Container-typed node. |
