Explanation

Infrastructure as a Service (IaaS) provides virtualized computing resources-servers, storage, and networking-over the cloud. Because VMs are a core IaaS deliverable, it is the natural fit for a VM-based disaster recovery solution. Organizations can spin up VM replicas in the cloud and fail over to them when on-premises systems go down. PaaS abstracts away the underlying infrastructure, SaaS delivers finished applications, and Security as a Service is a security-management model-none of them give direct control over virtual machines the way IaaS does.
