Question 5

IaaS

Answer 5

Infrastructure as a service (IaaS) is the most flexible category of cloud services, as it provides you the maximum amount of control for your cloud resources.
With IaaS, you’re essentially renting the hardware in a cloud datacenter, but what you do with that hardware is up to you.
