How do you believe virtualization could help in datacenter consolidation?

1. Virtualization allows us to place the functionality of many servers into a single host while maintaining configurable levels of separation between all virtual machines. How do you believe virtualization could help in datacenter consolidation? What would you be leery about during and after any transition? 2. Does virtualization increase the cybersecurity posture of the organization? If so, describe how and why. If not, describe how and why not. 3. There are various virtualization options. Bare-metal (type 1) whereby the hypervisors run directly on the hardware as their own operating systems, and User-space (type 2) hypervisors that run within the conventional operating systems. Which of these options is more secure? Describe the vulnerabilities you believe exist in either type 1, type 2, or both configurations. Given that, what do you believe can be done to mitigate these vulnerabilities? 4. In the scholarly publication Xen and the Art of Virtualization, the authors describe a virtualization solution. Read the article and visit https://www.xenproject.org/ to gain a perspective on this open source solution, those that support it, and what it offers today. Why should organizations consider Xen as an open-source virtualization solution when they can purchase a solution for virtualization service providers such as Amazon?
