Your company is considering a move to in-house virtualization or maybe a cloud platform.  The application that is being moved is a web app that does not contain any sensitive data.  The apps usage pattern is very unpredictable and the company wants to be able to easily add/remove capacity as needed.  Make a recommendation for in-house virtualization or the cloud.  Explain why you think that is the correct choice.  Explain anything you might do to mitigate any obvious risks of your choice.
