Week 4 Discussions

3. Discussion # 1
Supporting Activity: Virtual Machines
Describe the three types of virtualization and at least two
benefits of virtualization.
Discussion # 2
Supporting Activity: Virtualization
What experiences have you had with virtualization in the past?
What are the benefits of using virtualization? How is it
achieved? What effects would implementing virtualization have
on an organization?
Discussion # 3
Supporting Activity: Fault Tolerance
What are the multiple aspects of a system that fault tolerance
should address? What are some of the methods used to achieve
fault tolerance? How would you make a choice between them?
