Architectural Concepts

Cloud computing is the most transformative development in information technology in the past decade. This chapter introduces the basic concepts of cloud computing and help readers understand the foundational material they will need to know as they begin their journey toward the Certified Cloud Security Professional certification. Once you have a clear picture of what your organization does in terms of lines of business and processes, you can get a better understanding of what benefits the organization might derive from cloud migration as well as the costs associated with the move. Conducting a cost/benefit analysis helps you understand this trade‐off in clear financial terms. Cloud deployment models describe different approaches to the way that organizations might implement cloud services. Essentially, they describe the place where the assets are hosted and who has access to them. The major cloud deployment models are private cloud, public cloud, hybrid cloud, multi‐cloud, and community cloud.
