Removing the faults in a stage-coach may produce a perfect stage-coach, but it is unlikely to produce the first motor car.

This chapter focuses on exploring the questions to ask cloud providers when considering their services, the categories of applications that should be placed on the cloud, the type of cloud to be used, areas to obtain additional cloud information and assistance, and how to get started in cloud computing.
Three common questions come up when an organization is considering using a cloud:

Also, applications ...
