Which scenario is the best use case for IaaS?

The best use case for Infrastructure as a Service (IaaS) is the scenario involving lifting and shifting on-premises systems to the cloud with minimal changes. This is because IaaS offers virtualized computing resources over the internet, allowing businesses to migrate their existing applications and systems with little to no modification. This model supports the replication of an existing infrastructure in the cloud, where organizations can take advantage of the scalability and flexibility of cloud resources while retaining their current operations and workflows.

By utilizing IaaS, organizations can effectively transition their workloads to the cloud without the need for extensive reconfiguration or redesign, thus minimizing disruption to their operations. The infrastructure provided is highly customizable, which means that businesses can tailor the computing environments to suit specific requirements while still benefiting from cloud advantages like remote access, automatic scaling, and infrastructure management.

In contrast, hosting websites without server management aligns more closely with Platform as a Service (PaaS), which abstracts server management tasks and simplifies application deployment. Rapidly creating complex applications in the cloud typically leverages PaaS or SaaS models, where the focus is on application development rather than infrastructure management. Finally, analyzing large datasets without needing local hardware often falls under the purview of specialized analytics services rather than Iaa
