If you have an NSX instance integrated with vRealize Automation, you can configure your vSphere blueprints to leverage NSX for network and security virtualization.
If you have configured vRealize Automation integration with NSX, you can use network, security, and load balancer components in the design canvas to configure your blueprint for machine provisioning. You can also add the following NSX network and security settings to the overall blueprint when you create a new blueprint or edit an existing blueprint.
Transport zone - contains the networks used for the provisioned machine deployment
Routed gateway reservation policy - manages network communication for the provisioned machine deployment
App isolation - allows only internal traffic between machines used in the provisioned machine deployment
NSX settings are only applicable to vSphere machine component types.
