Explain the concept of Infrastructure as a Service (IaaS).

Infrastructure as a Service (IaaS) is a cloud computing model where a third-party provider offers virtualized computing resources over the internet. It allows users to access and manage fundamental computing resources such as virtual machines, storage, and networking infrastructure, without the need to invest in physical hardware or infrastructure. With IaaS, users have the flexibility to scale their resources up or down based on their needs, pay for only the resources they use, and have the provider handle the maintenance and management of the underlying infrastructure.
