Cloud Service Models (IaaS / PaaS / SaaS) for Tech+
Short answer
Cloud computing provides resources/services over a network. IaaS (Infrastructure as a Service) - You rent compute/storage/network building blocks. - You manage the OS and applications. PaaS (Platform as a Service) - You rent a platform to deploy/run apps. - Less server/OS management; more focus on your app. SaaS (Software as a Service) - You use a finished application delivered as a service. - Provider manages the underlying infrastructure and platform. Scenario logic: - Want control of OS/config? -> IaaS - Want to deploy code without managing servers? -> PaaS - Just want to use the app?
