Define the cloud, and discuss its attributes. Answer: The cloud is defined as the elastic leasing of pooled computer resources over the Internet. The term cloud is used because most early diagrams of three-tier and other Internet- based systems used a cloud symbol to represent the Internet, and organizations came to view their infrastructure as being "somewhere in the cloud." The term elastic means that the computing resources leased can be increased or decreased dynamically, programmatically, in a short span of time and that organizations pay for just the resources that they use. Cloud resources are pooled because many different organizations use the same physical hardware; they share that hardware through virtualization. The cloud resources are accessed over the Internet , which refers to a set of standard ways of requesting and receiving services over the Internet_._ AACSB: Information Technology Difficulty: 2: Moderate Course LO: Discuss the key issues involved in managing the components of IT infrastructure LO: 6: Why is the cloud the future for most organizations?

Explain the relevance of cloud-based hosting today. Answer: Three factors have made cloud-based hosting advantageous today. First, processors, data communication, and data storage are so cheap that they are nearly free. Because data communication is so cheap, getting the data to and from that processor is also nearly free. Second, virtualization technology enables the near instantaneous creation of a new virtual machine. The customer provides (or creates in the cloud) a disk image of the data and programs of the machine it wants to provision. Virtualization software takes it from there. Finally, as stated, Internet-based standards enable cloud-hosting vendors to provide processing capabilities in flexible yet standardized ways.

What is a digital subscriber line (DSL)? Answer: Digital subscriber lines (DSLs) operate on the same lines as voice telephones, but they operate so that their signals do not interfere with voice telephone service. Because DSL signals do not interfere with telephone signals, DSL data transmission and telephone conversations can occur simultaneously. A device at the telephone company separates the phone signals from the computer signals and sends the latter signal to the ISP. Digital subscriber lines use their own protocols for data transmission.
