A company has developed an application that is running Windows Server on VMware vSphere VMs that the company hosts on premises. The application data is stored in a proprietary format that must be read through the application. The company manually provisioned the servers and the application.

The company wants the application to return to on-premises hosting after a disaster recovery event is complete. The RPO is 5 minutes.
