# AWS.Deployment.VNFDeployment
<a name="node-vnf-deployment"></a>

NF deployments are modeled by providing the infrastructure and the application associated to it. The [cluster](#node_vnf_deployment_cluster) attribute specifies the EKS cluster to host your NFs. The [vnfs](#node_vnf_deployment_vnfs) attribute specifies the network functions for your deployment. You can also provide optional lifecycle hooks operations of type [pre\$1create](#node_vnf_deployment_pre_create) and [post\$1create](#node_vnf_deployment_post_create) to run instructions specific to your deployment, such as calling an Inventory Management system API.
