In recent years, a remarkable transformation has taken place in the business landscape as organizations of all sizes and industries are increasingly embracing cloud technology. Cloud computing has emerged as a game changer, reshaping the way companies operate, make decisions, and design their architectural frameworks. This paradigm shift is driven by many factors, with two prominent reasons standing out: cost savings and the ability to accomplish more with fewer resources. At the forefront of this cloud revolution is Microsoft Azure.

One of the primary drivers compelling business decision makers and architects to adopt cloud solutions is the potential for substantial cost savings. Traditional on-premises infrastructure demands substantial upfront investments in hardware, software licenses, and dedicated IT staff to maintain and manage the infrastructure. With Azure, organizations can opt for a pay-as-you-go model, where they only pay for the resources and services they use. We will learn more about this in Chapter 11, Cost governance on Azure.

Azure enables companies to do more with less, amplifying the impact of their resources. Businesses can tap into virtually unlimited computing power and storage capacity, allowing them to scale their operations seamlessly. We will learn more about this in Chapter 2, Achieve availability, scalability, and monitoring with Azure.

Within the realm of cloud computing, Microsoft Azure provides three distinct cloud models, each defining the level of control and maintenance responsibilities for customers. These cloud models facilitate the segregation of responsibility. In the upcoming section, we will examine each of these models, exploring how they help businesses to effectively manage their cloud resources.

Segregation of responsibility is an important concept in cloud computing, particularly in environments where multiple teams or individuals have access to shared resources. Understanding how segregation of responsibility works in different Azure cloud models can help ensure that your organization’s data and resources are protected and managed effectively.

There are three different deployment patterns that are available in Azure:

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

The differentiation among these three deployment patterns is the level of control customers have over their resources through Azure.

IaaS

IaaS is a type of deployment model that allows customers to provision their own infrastructure on Azure. Azure provides several infrastructure resources and customers can provision them on demand. Customers are responsible for maintaining and governing their own infrastructure, while Azure takes care of the maintenance of the physical infrastructure on which the virtual infrastructure resources are hosted. This approach requires customers to actively manage and operate within the Azure environment.

PaaS

PaaS eliminates the need for customers to handle infrastructure deployment and control, offering a higher-level abstraction compared to IaaS. In this approach, customers bring their own application, code, and data, and deploy them on the platform provided by Azure. These platforms are managed and governed by Azure, while customers retain sole responsibility for their applications. Since Azure manages the underlying infrastructure, customers can focus solely on activities related to their application deployment. This model facilitates faster and simpler options for application deployment when compared to IaaS.

SaaS

SaaS represents a higher-level abstraction in comparison to PaaS. In this approach, customers have access to software and its associated services for their consumption. The services are fully managed by the provider. Customers only need to bring their data into the SaaS environment without any control over the underlying infrastructure or services.

Figure 1.1 illustrates the areas of responsibility between customers and Microsoft, spanning SaaS, PaaS, IaaS, and on-premises.

Figure 1.1: Segregation of responsibilities

Regardless of the deployment type or cloud model, you retain ownership of your data and identities. It is your responsibility to protect the security of your data, identities, on-premises resources, and the components within your control in the cloud.

The following responsibilities are always retained by you regardless of deployment type:

• Information and data
• Devices (mobile and PCs)
• Accounts and identities

Understanding the segregation of responsibility across different Azure cloud models is crucial for ensuring the security and integrity of your organization’s data and resources. With the robust security and compliance features of Azure and the implementation of best practices for managing and securing your Azure environments, organizations can effectively protect and manage their data and applications.
