Cloud Services Virtualization (IaaS) An online business’s website receives higher traffic during peak holiday shopping times. Purchasing and configuring additional servers to meet this demand for the short term can be an expensive task for companies managing complex computing environments. To minimize cost and maximize performance, companies often use virtualization software rather than purchasing and installing additional memory, storage, or processing power. Virtualization software allows one physical machine to emulate the capabilities of one or more servers. Virtualization is an example of infrastructure as a service (IaaS), a service of cloud computing that allows users to configure a computing environment’s hardware, devices, storage, and operating systems using software. Amazon Web Services and Microsoft Azure are two cloud providers of virtualization services. (To learn more about virtualization, visit Chapter 9’s free resources and read the High-Tech Talk article on this topic.) Research This: (1) Use a search engine to find current articles, websites, or reviews of the virtualization offerings of Microsoft Azure and Amazon Web Services. (2) Find a case study about a company using Microsoft Azure or Amazon’s virtualization services, summarize the problem the company was trying to solve, and describe how virtualization played a part in solving it. (3) Refer to the Chapter 6 Internet Research activity on private, public, and hybrid clouds. Why is running a private cloud in a virtualized environment a popular cloud computing solution?
