Many companies are undergoing server virtualization. This is the concept of putting multiple "virtual" servers onto one physical device. The payoffs can be significant: fewer servers, less electricity, less generated heat, less air conditioning, less infrastructure and administration costs, increased flexibility, less physical presence (that is, smaller server rooms), faster maintenance of servers, and more. There are costs, of course, such as licensing the virtualization software, labour costs in establishing the virtual servers onto a physical device, labour costs in updating tables, and access.

2. Many companies are undergoing server virtualization. This is the concept of putting multiple“virtual” servers onto one physical device. The payoffs can be significant: fewer servers, lesselectricity, less generated heat, less air conditioning, less infrastructure and administrationcosts, increased flexibility, less physical presence (that is, smaller server rooms), fastermaintenance of servers, and more. There are costs, of course, such as licensing thevirtualization software, labour costs in establishing the virtual servers onto a physical device,labour costs in updating tables, and access. But determining the return on investment can be achallenge. Some companies have lost money on server virtualization, while most would saythat they have gained a positive return on investment but have not really quantified theresults.(b) Is this a project that a systems analyst might be involved in? Why or why not?
Is there a downside to a two-tier architecture?A multitier client–server strategy may be able to address this issue.
Consider a data center heavily built on Hyper-V, and the ability to clone virtual machines from template VMs or from other existing VMs. How do the deployment options of such a highly virtualized data center change the deployment options from those available for traditional data centers? Is there any benefit from, or need for, the use of some traditional deployment options? What are the drawbacks of using VMs, if any?
