Azure AZ-900 Fundamentals Exam

Overview

Azure provides a variety of compute and networking services that are essential for building and managing applications in the cloud. These services help you run applications, manage resources, and connect different parts of your infrastructure. Understanding these services is crucial for anyone preparing for the Azure AZ-900 Fundamentals Exam.

Azure Compute Services

Azure compute services allow you to run applications and manage workloads in the cloud.

These services include:

• Virtual Machines (VMs): These are customizable computing resources that you can use to run applications just like you would on a physical computer. You can choose the operating system, size, and configuration of your VMs.

• App Services: This is a platform-as-a-service (PaaS) offering that allows you to build, deploy, and scale web apps and APIs quickly. It supports multiple programming languages and frameworks.

• Azure Functions: These are serverless compute services that let you run small pieces of code without managing the underlying infrastructure. They are ideal for tasks that respond to events or triggers.

• Azure Kubernetes Service (AKS): This service simplifies the deployment, management, and operations of Kubernetes, an open-source system for automating the deployment, scaling, and management of containerized applications.

Azure Networking Services

Azure networking services help you connect and manage your cloud and on-premises resources.

These services include:

• Virtual Networks (VNet): VNets allow you to create isolated networks in the Azure cloud. You can control IP address ranges, subnets, and security settings to ensure your resources are secure and accessible.

• Load Balancer: This service distributes incoming network traffic across multiple VMs or services to ensure high availability and reliability. It helps prevent any single resource from becoming a bottleneck.

• Azure VPN Gateway: This service enables you to create secure connections between your on-premises networks and Azure VNets. It supports site-to-site, point-to-site, and VNet-to-VNet connections.

• Azure Content Delivery Network (CDN): This service delivers high-bandwidth content to users around the world by caching content at strategically placed physical nodes. It helps improve the performance and reliability of your applications.

Key Points to Remember

• Scalability: Azure compute and networking services are designed to scale up or down based on your needs. This flexibility ensures that you only pay for what you use.

• Security: Azure provides built-in security features such as network security groups, firewalls, and encryption to protect your data and applications.

• Integration: Azure services are designed to work seamlessly together, allowing you to build comprehensive solutions that meet your business requirements.

By understanding these core Azure compute and networking services, you will be better prepared for the Azure AZ-900 Fundamentals Exam. These services form the foundation of many cloud-based solutions and are essential for managing and optimizing your cloud infrastructure.
