What is a key feature of Infrastructure as a Service (IaaS)?

A key feature of Infrastructure as a Service (IaaS) is the provisioning of virtualized computing resources over the internet. This aspect highlights the fundamental nature of IaaS, which provides users with access to a range of scalable and flexible computing resources, such as virtual machines, storage, and networks. Unlike traditional data centers, IaaS enables users to deploy and manage their infrastructure without the need for physical hardware, allowing for greater efficiency, reduced costs, and improved agility in responding to varying workloads. By leveraging IaaS, businesses can easily scale resources up or down based on their evolving needs, ultimately enhancing their operational capabilities and responsiveness.

The other options do not align with the core offerings of IaaS. For instance, managing software applications typically falls under Software as a Service (SaaS). Integration of development environments is more specific to Platform as a Service (PaaS), which provides tools and platforms for developers. Data analytics capabilities can be part of various cloud services but are not a defining feature of IaaS. Therefore, the correct identification of IaaS focuses prominently on its ability to deliver virtualized infrastructure resources, making option B the most appropriate choice.
