Answer: infrastructure as a service (IaaS)

The lift-and-shift migration approach, also known as rehosting, involves moving existing on-premises servers to the cloud with minimal or no modifications. This strategy is best suited for Infrastructure as a Service (IaaS) because IaaS provides virtual machines that closely mimic on-premises infrastructure, allowing organizations to migrate their servers directly without significant architectural changes. The community discussion strongly supports this with 100% consensus on answer A, with comments highlighting that lift-and-shift is a key feature of IaaS and involves moving workloads to Azure Virtual Machines. Platform as a Service (PaaS) and Software as a Service (SaaS) are less suitable because they require more application-level changes or complete abstraction of infrastructure management, which contradicts the minimal-change principle of lift-and-shift.
