Differentiate between Infrastructure as a Service (IaaS), enhanced IaaS (Iaas+) and Platform as a Service (PaaS). We define IaaS+, which remains an infrastructure virtualization solution, and make clear the benefits of providing making the application (instead of the virtual machine) the first class abstraction with which developers and operations teams interact. When enough functionality is available around the *application* devops practices provide greater value.
