Which of the following allows companies to pass the operation of their computer systems to another company?
A. BPaaS
B. SaaS
C. PaaS
D. Virtualization
E. IaaS
The correct answer and explanation is:
The correct answer is E. IaaS (Infrastructure as a Service).
Explanation:
IaaS is a cloud computing model that provides virtualized computing resources over the internet. It allows companies to outsource the operation of their computer systems and infrastructure to a third-party provider. This includes services such as computing power, storage, networking, and the virtualization of hardware.
When a company chooses IaaS, it doesn’t need to manage physical servers, storage, or networking hardware. Instead, it can access these resources over the cloud on-demand. IaaS providers typically offer a flexible pay-as-you-go pricing model, which can be scaled up or down according to the company’s needs. This flexibility is a significant advantage, especially for businesses that may have fluctuating demand or those that don’t want to invest heavily in physical infrastructure.
Companies using IaaS only need to manage the software they install on the virtual infrastructure, like operating systems and applications, while the cloud provider takes care of the physical infrastructure and virtualization layer. This helps businesses reduce their IT costs, minimize hardware management complexity, and increase operational efficiency.
IaaS is ideal for companies that need to scale their operations without having to invest in and maintain their own physical servers. It also facilitates greater focus on innovation, as companies can leverage the cloud’s flexibility and resources without worrying about maintaining the underlying infrastructure. Popular IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
In contrast to other models like SaaS (Software as a Service) and PaaS (Platform as a Service), which offer specific software and platform tools, IaaS provides the most fundamental layer of IT infrastructure, giving businesses the freedom to build and customize their systems as needed.
