3 Leveraging the Cloud for Digital Transformation

AWS has come a long way since Amazon started in 2006 when it offered just two primary services. In this chapter, you will begin by understanding cloud computing models. Further, you will learn the differences between Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) and how AWS complements each model with its services and infrastructure. You will also learn how today’s businesses use AWS to transform their technology infrastructure, operations, and business practices completely.

In this chapter, we will cover the following topics:
