You need to migrate an on-premises server using a lift-and-shift approach. To which cloud service model should you migrate?

A lift-and-shift migration involves moving an existing application and its associated data to the cloud with minimal changes. IaaS is the most suitable cloud service model for this approach because it provides virtualized computing resources (servers, storage, networking) that closely resemble an on-premises environment. This allows you to migrate your existing server operating systems, applications, and data without significant re-architecture. PaaS would require modifying the application to fit the platform's specific frameworks and services, which contradicts the "minimal changes" aspect of lift-and-shift. SaaS involves consuming a fully managed application, offering no control over the underlying infrastructure, making it unsuitable for migrating an existing server.
