The Microsoft Azure Fundamentals AZ-900 exam is a certification designed to help you demonstrate your understanding of cloud computing principles and how they apply to Microsoft Azure. In this section, we will delve into the first domain of the AZ-900 exam, which covers the basic concepts of cloud computing, its various models, and key characteristics. By understanding the core concepts of cloud computing, you will be better prepared for the exam and for utilizing Azure services effectively.
Cloud Computing Basics
Cloud computing is the delivery of computing services—such as virtual machines, storage, databases, networking, software, and more—over the internet, often referred to as “the cloud.” This technology allows businesses and individuals to access computing resources on demand without needing to own or maintain physical hardware. The resources are typically provided by third-party cloud service providers like Microsoft Azure, Amazon Web Services (AWS), and Google Cloud.
The core advantage of cloud computing is its ability to offer scalability, flexibility, and cost efficiency. Traditional IT infrastructure often requires large upfront investments in hardware and long-term maintenance costs. With cloud computing, organizations can avoid these large capital expenditures and instead pay only for the services they use, often on a pay-as-you-go basis.
Key Features of Cloud Computing:
- On-Demand Self-Service: Cloud users can provision and manage resources (e.g., virtual machines, storage, networking) on-demand without requiring human interaction from the service provider.
- Broad Network Access: Cloud services are accessible over the internet through standard mechanisms such as web browsers, mobile apps, and APIs, making them available from anywhere with an internet connection.
- Resource Pooling: Cloud providers pool resources to serve multiple customers, using multi-tenant models where physical and virtual resources are dynamically assigned and reassigned according to demand.
- Rapid Elasticity: Cloud computing can scale resources up or down quickly to match fluctuating demands, allowing for flexibility and efficient cost management.
- Measured Service: Cloud services are billed based on actual usage, which means customers only pay for what they use, helping to reduce unnecessary costs.
Cloud Deployment Models
There are several different deployment models in cloud computing, each with its own set of advantages and trade-offs. These models determine how the cloud infrastructure is deployed and managed, and they help organizations select the best solution based on their needs.
- Public Cloud:
- In the public cloud model, the infrastructure and services are owned and operated by a third-party cloud provider, and they are made available to the general public.
- Examples of public cloud services include Microsoft Azure, AWS, and Google Cloud.
- Advantages: Lower cost (pay-as-you-go model), scalability, minimal management for users.
- Disadvantages: Less control over infrastructure, potential security concerns due to shared resources.
- In the public cloud model, the infrastructure and services are owned and operated by a third-party cloud provider, and they are made available to the general public.
- Private Cloud:
- A private cloud is a cloud infrastructure that is used exclusively by one organization. It may be hosted on-premises or by a third-party provider, but the resources are not shared with other organizations.
- Advantages: Greater control, enhanced security, and customization.
- Disadvantages: Higher costs, as the organization must bear the cost of hardware and maintenance.
- A private cloud is a cloud infrastructure that is used exclusively by one organization. It may be hosted on-premises or by a third-party provider, but the resources are not shared with other organizations.
- Hybrid Cloud:
- The hybrid cloud model combines both public and private cloud resources, allowing data and applications to be shared between them. This provides greater flexibility and optimization of existing infrastructure.
- Advantages: Flexibility to move workloads between private and public clouds as needed, improved security, and better scalability.
- Disadvantages: More complex to manage and integrate.
- The hybrid cloud model combines both public and private cloud resources, allowing data and applications to be shared between them. This provides greater flexibility and optimization of existing infrastructure.

- Advantages: Cost-effective for similar organizations, enhanced security.
- Disadvantages: Less control than a private cloud, but more than a public cloud.
- A community cloud is a multi-tenant cloud where the infrastructure is shared by several organizations that have common goals or needs, such as industry compliance or security.
Cloud Service Models
Cloud services are typically delivered through three main models, each providing different levels of control and management:
- Infrastructure as a Service (IaaS):
- In the IaaS model, the cloud provider supplies and manages the infrastructure—servers, storage, and networking—while the customer is responsible for configuring the operating system, applications, and data.
- Example: Azure Virtual Machines (VMs), AWS EC2.
- Advantages: Customers can scale infrastructure resources up or down as needed and pay only for what they use.
- Disadvantages: Requires more technical expertise and management compared to PaaS or SaaS.
