Cloud Service Models

Abstract

This chapter covers the various cloud service models. The three main service models outlined by NIST are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). We go over these three service models and a few of the newer service models that are starting to be become prominent, including Database as a Service (DbaaS), Desktop as a Service (DaaS), and Security as a Service.
