IaaS is where we find the system administrators (SysAdmins). In a typical IaaS offering, the IaaS service provider is responsible for the provisioning of the hardware, networking, and storage, as well as any virtualization necessary to create the IaaS environment. The SysAdmin is responsible for everything built on top of that, including the operating system, developer tools, and end-user applications as needed.

The IaaS service may be created to handle resource surge needs, to create a development environment for a distributed DevOps team, or even to develop and offer SaaS products.
