What does Infrastructure-as-a-Service (IaaS) provide access to?

Infrastructure-as-a-Service (IaaS) provides access to virtualized computing resources over the internet. This model allows users to manage and utilize virtual servers, storage space, and networking capabilities without needing to invest in physical hardware. With IaaS, organizations can quickly spin up or scale down resources according to their needs, offering flexibility and efficiency.

Unlike cloud-based software applications, which fall under Software-as-a-Service (SaaS), IaaS primarily focuses on the foundational infrastructure that supports applications and data rather than providing specific software solutions. Similarly, development platforms are associated with Platform-as-a-Service (PaaS), which allows developers to build and deploy applications without dealing with the underlying infrastructure. While security is paramount in cloud environments, security for web applications is typically addressed by additional services or solutions rather than being a core offering of IaaS. Thus, the correct answer highlights that IaaS is fundamentally about delivering essential computing resources such as virtual servers, networks, and storage.
