Discussion questions

 Discussion Points 1. Do some Internet research to identify businesses who have suffered because of cloud security weaknesses or failures. What can companies who are contemplating cloud computing services learn from the negative experiences of these businesses?
 2. Do some Internet research on security mechanisms associated with virtualization. How can virtualization be used by cloud service providers to protect subscriber data? C11-5 
3. Choose one of the following cloud services categories: SaaS, IaaS, PaaS. Do some Internet research that focuses the security issues associated with the selected cloud service category.
