Chapter 5. Cloud Models
In this chapter, you’ll learn about the foundational categories of cloud environments, often referred to as cloud models.
If you’re already familiar with this topic, you can skip ahead to Part II.
What Are Cloud Models?
Cloud models define how computing resources, such as servers, storage, and applications, are deployed, managed, and delivered in the cloud. These models dictate the level of access, control, and ownership of the infrastructure and services provided.
The main types of cloud models are:
-
Public
-
Private
-
Hybrid
-
Multi-cloud
Each cloud model has unique characteristics and deployment scenarios. Let’s look at each model in detail.
Public Cloud
Public cloud, as the name suggests, is a computing service that is made available to the general public over the internet. Typically, public cloud services and resources are built, managed, and controlled by a third-party cloud provider. With public cloud, anyone seeking cloud services can access and use these resources and services based on the access privileges granted to them. Table 5-1 compares the top three public cloud providers.
Tip
Microsoft Azure is a prime example of a public cloud provider. Azure owns and operates the underlying infrastructure, allowing individuals or organizations to easily subscribe and onboard to the service with a credit card transaction.
