Infrastructure Delivery Model. “Cloud computing” means the delivery of computer processing services via the Internet. It is a new form of traditional IT infrastructure outsourcing with a limited, commoditized scope (volumes of server processing and storage capacity) and with no right of the enterprise customer to change anything other than such volumes. Cloud computing “steals the thunder” from IT infrastructure outsourcing by removing a large chunk of services from the scope of what an IT infrastructure service provider would have otherwise delivered (e.g., tape backup, disaster recovery, testing and restoration).
Virtualization. Virtualization of computer servers – using new software that allows splitting processing amongst diverse computers – operates over the Internet.
