Section 1: virtualization uses software-based partitions to create multiple virtual servers- called virtual machines-on a single physical server. The major benefit of this system is that each server no longer has to be dedicated to a particular task. Instead, multiple applications can run on a single physical server, with each application running within its own software environment. As a result, virtualization enables companies to increase server utilization. In addition, companies realize cost savings in two areas. First, they do not have to buy additional servers to meet peak demand. Second, they reduce their utility costs because they are using less energy. Answer the below Questions 1. Give some companies / technologies that are making Virtualization possible. Section 2: There are three major types of cloud computing that companies provide to customers or groups of customers: public clouds, private clouds, and hybrid clouds. ORGANIZATION A cloud Hybrid cloud Private cloud Public doud INTERNET ORGANIZATION B ORGANIZATION C Private Private cloud cloud 1. What is a public cloud? 2. What is a private cloud? 3. What is a hybrid cloud? Give some examples of the above implementations and also list benefits and drawbacks of each implementation. 4. Describe how cloud computing can help organizations expand the scope of their business operations. 5. Describe how cloud computing can help organizations respond quickly to market changes. Section 3: Cloud computing services are based on three models: infrastructure-as-a-service (laaS), platform-as-a-service (PaaS), and software-as-a-service (Saas). These models represent the three types of computing generally required by consumers: infrastructure to run software and store data (laaS), platforms to develop applications (PaaS), and software applications to process their data (Saas).
