# CreateSolNetworkInstance
<a name="API_CreateSolNetworkInstance"></a>

Creates a network instance.

A network instance is a single network created in AWS TNB that can be deployed and on which life-cycle operations (like terminate, update, and delete) can be performed. Creating a network instance is the third step after creating a network package. For more information about network instances, [Network instances](https://docs.aws.amazon.com/tnb/latest/ug/network-instances.html) in the * AWS Telco Network Builder User Guide*.

Once you create a network instance, you can instantiate it. To instantiate a network, see [InstantiateSolNetworkInstance](https://docs.aws.amazon.com/tnb/latest/APIReference/API_InstantiateSolNetworkInstance.html).
