IaaS takes existing technologies such as virtualization but delivers them on a subscription basis, such as provisioning servers, storage and networking.
With IaaS an organization doesn’t need to think about buying and provisioning hardware before being able to use the compute, storage or bandwidth.

In relation to the cloud computing stack, IaaS is the foundation of cloud, the plumbing if you like.
