Cloud consumers try to find solutions to their business and technical needs while searching for cloud service provider offerings that meet their functional and non-functional requirements. Cloud customers look at the service models that the cloud service providers offer and their pricing, and based on that information they are able to conduct a cost and benefit analysis for their business case. The ISO/IEC 17788:2014 (https://www.iso.org/standard/60544.html) standard provides an overview of cloud computing along with a set of terms and definitions for cloud computing, which makes it easier to learn about and discuss the many facets of this technology. You will see this later in the chapter.

The standard describes the following three primary types of cloud service models:

• Software as a Service (SaaS)
• Platform as a Service (PaaS)
• Infrastructure as a Service (IaaS)

You will now review each one of these capabilities separately and examine...

Cloud computing services are often provided as one of three main service models, also known as service categories. In order to pass the CCSP exam, the (ISC)2 CBK requires you to know the cloud service models and be able to describe their differences.

The NIST Special Publication 800-145 titled The NIST Definition of Cloud Computing defines three fundamental cloud computing service models as follows:

• IaaS: IaaS is the capability provided to the cloud consumer to provision processing, storage, networks, and other fundamental computing resources where you are able to deploy and run arbitrary software that can include operating systems and applications. The consumer not only manages or controls the underlying cloud infrastructure but also has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls).
• PaaS: PaaS is the capability provided to the...

Another perspective for looking at cloud computing has to do with the ownership level of cloud infrastructure components rather than looking at the service types being provisioned and utilized. For the CCSP exam, you will be expected to know and learn the following cloud deployment models:

• Public cloud
• Private cloud
• Hybrid cloud
• Community cloud
• Multi-cloud

At a high level, you have the first two opposing models, with clear differences in the approach to the ownership level of cloud computing infrastructure components: the public cloud versus the private cloud. Then there are the hybrid and community clouds, with varying levels of ownership and co-sharing of the cloud infrastructure components between customers. The last cloud deployment model, recently introduced to the CCSP CBK, is the multi-cloud deployment model, which is a result of the fact that many cloud customers utilize cloud services from multiple cloud service providers...

The adoption of cloud computing involves several considerations that will lead to a combination of technical and business decisions for both cloud service providers and cloud customers. In this section, you will explore several key considerations for cloud deployments:

• Interoperability: In cloud computing, interoperability can be defined as the capacity of cloud ecosystem components to operate together in achieving desired outcomes. The components of a cloud computing ecosystem may come from several sources, including traditional and cloud sources, as well as public and private cloud implementation (known as hybrid cloud).
• Portability: This is the capability of cloud components to be moved or reused in different cloud deployment models, providers, platforms, infrastructures, and locations, with little or no modification (e.g., without converting the program to a different language). When choosing cloud providers, portability is...

Cloud computing characteristics such as resource pooling, automation, scalability, and the innovative use of virtualization allowed for the development of many new and emerging technologies that provide businesses around the world with new capabilities. You will review some of the most notable new technologies that were developed as a result of growing cloud adoption, or which are taking cloud computing into new emerging areas.

Data Science

Data science has revolutionized how businesses analyze, process, and utilize vast amounts of data in order to gain insights and make decisions based on that knowledge. With cloud computing’s continuing evolution in offering more services and platforms for data scientists to collaborate on their work, innovate within their field, and scale operations, data scientists now have an ideal environment in which they can collaborate, innovate, and scale operations.

Cloud computing is seeing the emergence...

In this chapter, you learned about cloud service capabilities and how they relate to cloud service models. You also learned about the different types of cloud deployment models and how responsibilities change depending on the cloud deployment models and cloud service models being offered and used. Many new and emerging technologies which are related to cloud computing were also introduced.

For your CCSP exam, make sure you grasp the definitions that are introduced in this chapter. Many CCSP exam questions focus on key cloud terms and definitions. You need to be able to describe different cloud service models. It is very important that you know the differences between the three cloud service models—IaaS, PaaS, and SaaS—and the different features and characteristics associated with them. It is vitally important that you grasp the features of the five cloud deployment models—public, private, community, hybrid, and multi-cloud—as well as being able...

Apart from a solid understanding of key concepts, being able to think quickly under time pressure is a skill that will help you ace your certification exam. That is why working on these skills early on in your learning journey is key.

Chapter review questions are designed to improve your test-taking skills progressively with each chapter you learn and review your understanding of key concepts in the chapter at the same time. You’ll find these at the end of each chapter.
