It is available on Windows, macOS, and Linux, making it a flexible choice for administrators and developers who prefer working from a terminal rather than a graphical interface. As part of Azure management and governance, the Azure CLI plays a key role in helping users create, configure, and control cloud resources efficiently.
With Azure CLI, you can perform a wide range of tasks such as creating virtual machines, managing storage accounts, deploying applications, and configuring networking. Commands follow a consistent structure, typically starting with 'az' followed by a service group and an action. For example, 'az vm create' is used to create a virtual machine. This predictable syntax makes it easier to learn and remember common operations.
One of the main advantages of Azure CLI is its support for automation and scripting. You can write scripts that combine multiple commands to automate repetitive tasks, ensuring consistency and saving time. This is especially valuable for governance, as it helps organizations enforce standardized configurations across their environments and reduces the chance of human error.
Azure CLI also integrates well with other tools and can be used inside Azure Cloud Shell, a browser-based shell that requires no local installation. Cloud Shell comes pre-configured with the CLI, allowing you to start managing resources right away from anywhere.
For authentication, Azure CLI uses your Azure credentials and respects role-based access control, meaning users can only perform actions permitted by their assigned roles. This supports secure and compliant resource management.
Overall, Azure CLI is a powerful, efficient, and portable option for interacting with Azure. It complements the Azure portal and PowerShell, giving users multiple ways to manage cloud environments based on their preferences and needs.
Azure CLI
Azure CLI (Command-Line Interface) is a cross-platform command-line tool used to manage and administer Azure resources. It allows you to create, configure, and control your Azure services using text-based commands, either from your local machine or through the Azure Cloud Shell in a browser.
Why Azure CLI is Important
Understanding Azure CLI is essential for anyone working with Azure because it provides a fast, repeatable, and scriptable way to manage cloud resources. While the Azure Portal offers a graphical experience, the CLI enables automation and consistency, making it a favourite among administrators and developers who prefer efficiency over clicking through menus.
Key reasons it matters: - It supports automation through scripts, saving time on repetitive tasks. - It works across Windows, macOS, and Linux, offering flexibility. - It integrates well with DevOps pipelines and configuration management tools. - It provides consistent results when deploying resources multiple times.
What Azure CLI Is
Azure CLI is a set of commands that follow a clear structure. Each command begins with the keyword az, followed by a group (such as a service name) and a subcommand (an action). For example, az vm create is used to create a virtual machine, where vm is the group and create is the action.
You can install Azure CLI locally, or use it through the Azure Cloud Shell, which comes preinstalled and requires no setup. The Cloud Shell is accessible right from the Azure Portal and supports both Azure CLI and PowerShell.
How Azure CLI Works
When you run an Azure CLI command, it communicates with the Azure Resource Manager (ARM), which processes the request and applies changes to your resources. The typical workflow involves a few steps:
1. Authenticate using the command az login, which signs you into your Azure account. 2. Select a subscription if you have more than one, using az account set. 3. Run commands to manage resources, such as creating a resource group with az group create. 4. Review output, which can be formatted as JSON, table, or other styles for easy reading.
Azure CLI is designed to be readable and consistent, which makes it approachable even for beginners. Commands can be combined into scripts to deploy entire environments in a single run.
Common Commands to Remember
- az login signs you into your Azure account. - az group create creates a new resource group. - az vm create provisions a new virtual machine. - az account list shows your available subscriptions. - az resource list displays your existing resources.
Exam Tips: Answering Questions on Azure CLI
When you face exam questions about Azure CLI, keep these strategies in mind:
- Remember that every Azure CLI command starts with az. If an answer option starts with something else, it is likely a distractor. - Know that Azure CLI is cross-platform, meaning it runs on Windows, macOS, and Linux. This is a common point tested in the exam. - Be aware that PowerShell is an alternative tool that uses cmdlets like New-AzVM, so watch for questions asking you to tell the two apart. - Understand that the Azure Cloud Shell already includes Azure CLI, so no installation is needed when using it. - If a question mentions automating repetitive tasks or scripting deployments, Azure CLI is often the correct choice. - Focus on the command structure: az [group] [subcommand] [parameters]. Recognising this pattern helps you eliminate wrong answers quickly.
By mastering the purpose, structure, and everyday commands of Azure CLI, you will be well prepared to confidently handle related questions on the AZ-900 exam.
