AWS has come a long way since Amazon started in 2006 when it offered just two basic services. In this chapter, you will begin with understating of 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:
- A brief introduction to cloud computing
- Cloud computing models PaaS, IaaS, and SaaS
- Cloud migration strategy
- Implementing a digital transformation program
- AWS Cloud Adoption Framework (CAF)
Without further ado, let's get down to business.
