The answer is: Not needing to manage physical servers, Using a server for a short amount of time.
Step-by-step explanation:
Infrastructure as a service (IaaS) is a form of cloud computing that provides virtualized computing resources through the Internet.
Organizations choose IaaS because it is often easier, faster and more profitable to operate a workload without having to buy, manage and support the underlying infrastructure. With IaaS, a company can simply rent or lease that infrastructure from another company.
IaaS is an effective model for workloads that are temporary, experimental or unexpectedly changing.
