A wastewater utility wants full control of guest OS hardening on cloud servers that run a SCADA support tool. Which service type best matches that control need?
Select an answer to reveal the explanation.
Short Explanation
If you still need to lock down the OS yourself, you are in IaaS territory. PaaS and SaaS hide or remove that guest-OS knob on purpose. Rent the VM, keep the hardening playbook—that is the trade-off.
Full Explanation
Organizations choose IaaS when they need OS-level control—hardening, patching, and installing specialized software—while still renting compute from a cloud provider. PaaS and SaaS shift more of that stack to the provider and are poor fits when guest OS control is a hard requirement.
