The example above shows one of the possible ways to implement a node type, through implementation script artifacts. These scripts may include a special logic that communicates to a "factory" node inside the service. In this example, the capability of being a firewall and the capability of providing firewall are combined in one node. More elaborate designs may separate these functionalities and have a dedicated node for each of them. 

All other TOSCA ways to implement an abstract node are also valid. Foe For example, a vendor may choose to have an implementing (substituting) topology for this node type.
