What is one of the primary advantages of using Infrastructure as a Service (IaaS)?

One of the primary advantages of using Infrastructure as a Service (IaaS) is the scalability of resources on-demand. IaaS allows organizations to access virtualized computing resources over the internet, enabling them to scale up or down based on their current needs without having to invest in physical hardware. This flexibility is particularly valuable during peak usage times or when launching new projects, as companies can quickly provision additional resources, such as storage, computing power, and networking capabilities. As their needs change, they can also deallocate resources to save costs, making IaaS a highly efficient and cost-effective solution for managing IT infrastructure.

The other options do not accurately represent the core benefits of IaaS. While there may be scenarios where hardware costs can be significantly reduced, the complete elimination of all hardware costs isn’t feasible since the underlying infrastructure still exists, albeit virtualized. Complete control over application code is more aligned with Platform as a Service (PaaS) offerings, where the focus is on application development rather than the underlying infrastructure. Lastly, IaaS typically requires internet connectivity to access resources remotely, which is inconsistent with the concept of removing the need for internet access.
