CHAPTER 15Cloud Computing

This chapter provides an overview of cloud deployment models, cloud computing attributes and benefits, the cloud transformation and migration framework, the enterprise's roadmap and strategy to move to cloud‐based applications, and some of the typical use cases that trigger an enterprise to take the transformation journey to the cloud and make the enterprise intelligent.

Cloud Overview

The C‐suite executive of an enterprise purchases solutions to a complex problem faced by the organization and not the technology itself. While traditionally organizations have managed all their IT infrastructure internally, cloud computing allows the IT and business users to access data, applications, and services over the internet, where the infrastructure is managed by cloud service providers such as Amazon, Microsoft, Google, etc.
