Explanation

Infrastructure as a service (IaaS) is the correct service model for moving App1 to the cloud because it requires access to a specific operating system and database environment. IaaS provides the flexibility to host legacy applications and databases without having to make changes to the underlying architecture. With IaaS, you can manage the infrastructure and the application while the cloud provider manages the underlying hardware.
