A parks department proposes renting virtual machines in a cloud datacenter to run a legacy permit database. Which cloud service type describes that proposal?
Select an answer to reveal the explanation.
Short Explanation
Think of IaaS like renting the empty warehouse and the power—then you still stock the shelves. The cloud gives you VMs, storage, and network; the parks team still installs and patches the OS and that legacy permit database.
Full Explanation
Infrastructure as a service provides foundational compute, storage, and networking while the customer retains responsibility for the guest operating system, middleware, and applications. Running a legacy permit database on rented VMs is a classic IaaS use case. SaaS would mean consuming a fully hosted application, and PaaS would shift OS/runtime management to the provider for an application platform—not raw VMs the customer hardens.
