| Question | Answer |
|---|---|
| cloud access security broker | On-premise or cloud-based security policy enforcement points. |
| cloud bursting | Moving the execution of an application to the cloud on an as-needed basis. |
| cloud computing | A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. |
| community cloud | Cloud delivery model in which the infrastructure is shared by organizations with something in common. |
| hybrid cloud | Any cloud delivery model that combines two or more of the other delivery model types. |
| hypervisor | The software that allows virtual machines to exist. The machine running the hypervisor is known as a host, while the instances of virtual machines are known as guests. |
| Infrastructure as a Service (IaaS) | A model of cloud computing that utilizes virtualization; clients pay an outsourcer for the resources used. |
| National Institute of Standards and Technology (NIST) | An agency that has been involved in developing and supporting standards for the U.S. government for over 100 years. Involved in cryptography standards, systems, and technology in a variety of areas. It’s primarily concerned with governmental systems. |
| Platform as a Service (PaaS) | A cloud service model wherein the consumer can deploy but does not manage or control any of the underlying cloud infrastructure. |
| private cloud | A cloud delivery model owned and managed internally. |
| public cloud | A cloud delivery model available to others. |
| QoS (quality of service) | A collection of technologies that provide the ability to balance network traffic and prioritize workloads. |
| sandboxing | Isolating applications to keep users of them from venturing to other data. |
| Security as a Service | A subscription-based business model intended to be more cost effective than smaller individuals/corporations could ever achieve on their own. |
| Software as a Service (SaaS) | A model of cloud computing in which the consumer can use the provider’s applications, but they do not manage or control any of the underlying cloud infrastructure. |
| Type I hypervisor | Virtualization method that is independent of the operating system and boots before the OS. |
| Type II hypervisor | Virtualization method that is dependent on the operating system. |
| VDE A virtual desktop environment (VDE) | stores everything related to the user (wallpaper, folders, windows, and so on) remotely and client software locally simulates the user’s desktop environment and capabilities while running them on the host. |
| VDI Virtual desktop infrastructure (VDI) | is the process of running a user desktop inside a virtual machine that lives on a server in the datacenter. It enables fully personalized desktops for each user yet maintains centralized management and security. |
| virtualization | Emulating one or more physical computers on the same host. |
| VM escape | The act of breaking out of one virtual machine into one or more others on the same physical host. |
| VM sprawl | Growth that occurs on a large number of virtual machines and requires resources—usually administration related—to keep up with. |
