Which cloud service model provides the highest level of control over the underlying infrastructure?

Infrastructure as a Service (IaaS) provides the highest level of control over the underlying infrastructure because it allows users to manage both the operating systems and the applications running on the virtualized hardware. With IaaS, customers have the ability to provision and manage computing resources such as servers, storage, and networking, giving them significant flexibility and control over how those resources are configured and used.

In IaaS, users are responsible for managing the entire stack above the physical infrastructure, which includes the operating systems, middleware, and applications. This level of access allows organizations to optimize their infrastructure for their specific needs, implement custom security measures, and maintain better oversight of their resources.

In contrast, Software as a Service (SaaS) offers the least control, as users only access the software applications themselves without any management of the underlying infrastructure. Platform as a Service (PaaS) provides a balance, allowing users to manage applications and data without having to manage the underlying hardware and operating systems. Container as a Service (CaaS) provides a container management solution but is typically considered part of the PaaS or IaaS offering, limiting the level of control compared to IaaS.

Therefore, when looking for a cloud service model
