Chapter 2: Core Azure Services | MCQs for Azure Fundamentals (AZ-900)
Microsoft Azure is a comprehensive cloud platform offering a wide range of services that enable businesses to build, manage, and deploy applications through Microsoft’s global network of data centers. Azure’s architecture is designed for high availability and resilience, featuring Regions, Availability Zones, and Region Pairs, ensuring that services are always accessible. Resource Groups and Subscriptions are used to organize and manage resources, providing an efficient way to control access and monitor services.
Azure offers a variety of Compute Services, including Virtual Machines for scalable compute resources, Azure App Services for web and mobile app hosting, and Azure Functions, which supports serverless computing. Azure Kubernetes Service (AKS) simplifies container orchestration for deploying and managing containerized applications.
For networking, Azure provides Virtual Networks (VNets) for secure communication between services, Azure Load Balancer for traffic distribution, Azure Application Gateway for web traffic management, and Content Delivery Network (CDN) to deliver content with low latency globally.
Azure’s Storage solutions include Blob Storage for unstructured data, Disk Storage for virtual machine disks, and Azure Files and Queues for file storage and messaging services. Azure’s Databases portfolio encompasses Azure SQL Database, Azure Cosmos DB, and databases for MySQL, PostgreSQL, and MariaDB, offering high-performance, scalable data solutions. These services empower businesses to leverage the full potential of cloud infrastructure, from computation to storage and databases.
Chapter 2: Core Azure Services | For this set
2.1 Azure Architecture
- Regions, Availability Zones, and Region Pairs
Azure regions are geographically distributed locations that house data centers. Each region consists of multiple Availability Zones designed to ensure high availability and fault tolerance. Region Pairs provide redundancy by linking two regions within the same geography, allowing for disaster recovery in case of region-wide failure. - Resource Groups and Subscriptions
Resource Groups are logical containers used to organize Azure resources, making it easier to manage them. A Subscription is an organizational unit within Azure that allows users to access and manage resources, and it defines billing, access control, and usage limits.
2.2 Azure Compute Services
- Virtual Machines (VMs)
Azure Virtual Machines allow users to run applications and workloads in a virtualized environment. They offer flexibility in terms of OS, configurations, and scaling. - Azure App Services
Azure App Services provide a fully managed platform for building, deploying, and scaling web apps, APIs, and mobile backends, abstracting away infrastructure management. - Azure Functions
Azure Functions are a serverless compute service that enables users to run code in response to events without worrying about server management. - Azure Kubernetes Service (AKS)
AKS simplifies the deployment, management, and scaling of containerized applications using Kubernetes, enabling organizations to manage and orchestrate their containers efficiently.
2.3 Azure Networking
- Virtual Networks (VNets)
Azure Virtual Networks enable users to securely connect Azure resources to each other and to on-premises networks, ensuring isolated and private network environments. - Azure Load Balancer
Azure Load Balancer distributes incoming network traffic across multiple servers to ensure high availability and reliability of applications. - Azure Application Gateway
Azure Application Gateway is a web traffic load balancer that provides advanced routing and security features for web applications, including SSL termination and URL-based routing. - Content Delivery Network (CDN)
Azure CDN caches content at strategically located edge nodes, reducing latency and improving load times for end users globally.
2.4 Azure Storage
- Blob Storage
Azure Blob Storage is a scalable object storage service used to store unstructured data such as text and binary files. - Disk Storage
Azure Disk Storage provides high-performance, durable block storage for Azure Virtual Machines, supporting both standard and premium options. - Azure Files and Queues
Azure Files offer fully managed file shares in the cloud, accessible via SMB protocol, while Azure Queues enable asynchronous message queuing for communication between cloud-based services.
2.5 Azure Databases
- Azure SQL Database
Azure SQL Database is a fully managed relational database service, offering scalability, high availability, and security for mission-critical applications. - Azure Cosmos DB
Azure Cosmos DB is a globally distributed, multi-model database service designed for low-latency and high-throughput applications, supporting multiple data models like document, key-value, graph, and column-family. - Azure Database for MySQL, PostgreSQL, and MariaDB
Azure offers fully managed services for popular open-source databases, including MySQL, PostgreSQL, and MariaDB, ensuring scalability, security, and ease of management.
