Which service category allows customers to purchase servers and storage?

IaaS
PaaS
SaaS
TaaS

The correct answer is: IaaS

The correct answer is Infrastructure as a Service (IaaS). This service category provides customers with virtualized computing resources over the internet. IaaS allows businesses to rent servers, storage, and networking capabilities, making it easier to scale and manage their IT infrastructure without the need for physical hardware. Customers can provision and manage these resources on-demand, which enhances flexibility and reduces the costs associated with maintaining physical infrastructure. In contrast, Platform as a Service (PaaS) focuses on providing a platform that allows developers to build, deploy, and manage applications without having to deal with the underlying hardware and software layers. Software as a Service (SaaS) refers to software that is hosted and managed by a third-party provider and accessed through the internet, which does not typically involve purchasing servers or storage directly. Technology as a Service (TaaS) encompasses various technology services but does not specifically cater to the purchasing of servers and storage resources. Hence, IaaS is the most suitable option for acquiring servers and storage in a cloud environment.
