  38. General Steps to deploy a simple web application

  39. Discussion Questions What are the differences between terminating an instance and stopping it on Amazon AWS? How to clean up an instance on AWS if you won't use the instance anymore? What's the differences between shutting down a virtual machine and deleting it on Windows Azure?  What are the general steps of deploying a simple web applications onto EC2 and Windows Azure? How to authorize network access in EC2 and Azure? What is the role of the "key pair" in EC2? What is "instance image" in cloud? Why is the relationship between an instance and an image.
