Each layer encapsulates on-demand resources
Each layer comes with its own application development model
Three service layers:
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)

Cloud provider offers IT infrastructure (compute, storage, network, etc.) to customers
Virtualization is leveraged to dynamically combine resources in order to build and deliver ad hoc systems to the customer
Customers deploy their own software environment (i.e. virtual machine images) to run on these systems
Resources used by customers can grow and shrink on demand
