Cloud computing is a relatively new business model in the computing world. According to the official NIST definition, "cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction." The NIST definition lists five essential characteristics of cloud computing:

.2 Network Virtualization In computing, network virtualization is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external virtualization, combining many networks or parts of networks into a virtual unit, or internal virtualization, providing

Switching Technology Cassandra Anton Bellevue University Abstract Switching is a technology that has been used since the first communication networks were invented. In order to understand switching, we must first discuss switches. A switch is a device that connects other devices on a network. Switches can also prevent "bad" packets from spreading by not forwarding them on. While switches can be helpful to a network they should not be seen as an instant fix for network issues. There are many benefits

Virtualization is being able to give a physical device the power, through the use of software, to do more than that physical device was technically designed and able to do (Santana, 2014, p. 12). For example, a server can only run one operating system at a time. However, when a hypervisor is used in a server, the hypervisor is a layer of software that acts like the server itself so that many operating systems can be run from that one server. The hardware, in this case a server, has been virtualized
