题目
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. As part of its disaster recovery plan, the company wants the ability to host its application on AWS temporarily if the company's on- premises environment becomes unavailable. The company wants the application to return to on-premises hosting after a disaster recovery event is complete. The RPO is 5 minutes. Which solution meets these requirements with the LEAST amount of operational overhead?
