From the VMware vRealize Automation for ServiceNow ITSM application version 8.3, the Service Portal is available as a default portal for deployment. You can use the Service Portal to view Service Catalog, deployment, and resources. You can also perform various day-2 actions on associated deployments and resources. The ServiceNow users can either work on Service Portal or User Portal at a time.
To configure the User Portal, see Configure the User Portal.
