Cloud Computing Service Models Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
Cloud Delivery Models Private Public Community Hybrid
Virtualization Type I model is known as “bare metal.” Can boot without the operating system Type II model is known as “hosted.” Requires the operating system and is dependent on it
Virtualization Continued Containers and application cells Alternative to hypervisor; sometimes referred to as “Docker containers.” A piece of software is bundled with everything that it needs to run and deployed without the need to launch an entire VM for each application. Containers are an operating system–level virtualization method for running multiple isolated systems on a control host using a single kernel.
