A key distinction between Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) is the type of service offered by each segment. With IaaS, consumers usually work with virtualized servers, which they can configure themselves, whereas with PaaS, the consumer uses and works with services that are created and maintained by the cloud service provider. Figure 1 captures the basic differences between IaaS and PaaS.
