• Scripting and Automation: Azure CLI facilitates automation through scripting. Users can write scripts to define and deploy resources, allowing for streamlined and repeatable processes. This is particularly valuable in DevOps scenarios where rapid deployment and configuration changes are critical.
• Intuitive Syntax: Azure CLI utilizes a straightforward and consistent syntax for all commands. This reduces the learning curve for users who are already familiar with other command-line tools. The commands are designed to be self-explanatory, making them accessible even to beginners.
• Comprehensive Documentation: Microsoft provides extensive documentation for Azure CLI, including a detailed command reference, usage examples, and best practices. This documentation serves as a valuable resource for both newcomers and experienced users.
• Integration with Azure Services: Azure CLI seamlessly integrates with various Azure services, allowing users to manage a wide range of resources. Whether it’s creating virtual networks, managing databases, or configuring security policies, Azure CLI offers a unified interface.

Practical Applications

• Resource Provisioning: Azure CLI enables quick creation of resources. By writing scripts that define the desired configuration, users can effortlessly deploy resources like virtual machines, databases, and storage accounts.
• Deployment Automation: In a continuous integration and continuous deployment (CI/CD) pipeline, Azure CLI can be integrated to automate the deployment of applications and services. This ensures consistent and reliable deployments.
• Scaling Resources: With Azure CLI, users can dynamically scale their resources up or down as needed. This is crucial for handling varying workloads and optimizing resource utilization.
• Monitoring and Management: Azure CLI allows users to monitor the health and performance of their resources. By retrieving metrics and logs, administrators can gain insights into their applications’ behavior and take proactive measures.
• Security Configuration: Configuring security settings and access controls is made easier with Azure CLI. Users can define security rules, manage authentication, and implement encryption using command-line instructions.

Popular Azure CLI Commands

Azure CLI offers a rich set of commands that enable users to interact with and manage various Azure services. Here are some popular commands that demonstrate the versatility and utility of Azure CLI:

Login to Azure

az login

This command initiates the login process, allowing users to authenticate and access their Azure subscription. After successful authentication, users can begin managing their resources.

List Subscriptions

az account list --output table

This command lists all the Azure subscriptions associated with the logged-in account. It provides useful information such as subscription name, subscription ID, and the currently selected subscription.

Create a Virtual Machine

az vm create --resource-group myResourceGroup --name myVM --image UbuntuLTS --admin-username azureuser --admin-password Azure12345678

This command creates a virtual machine in the specified resource group with the provided parameters. Users can customize the image, VM name, and authentication credentials as needed.

Create a Storage Account

az storage account create --name mystorageaccount --resource-group myResourceGroup --location eastus --sku Standard_LRS

This command creates a storage account in the specified resource group, location, and SKU (Storage Account type). Storage accounts are essential for storing data objects such as blobs, files, and queues.

List Virtual Networks

az network vnet list --output table

This command retrieves a list of virtual networks within the current subscription. Virtual networks are fundamental for creating isolated network environments for resources like virtual machines.

Deploy Web App

az webapp up --sku F1 --name mywebapp

Deploy a web app with a free pricing tier. This command provisions the necessary resources and deploys the specified web application code to Azure.

List Resource Groups

az group list --output table

List all resource groups within the current subscription. Resource groups serve as containers for resources, allowing for improved organization and management.

Scale App Service Plan

az appservice plan update --name myplan --resource-group myResourceGroup --number-of-workers 3

Adjust the number of instances (workers) in an App Service Plan to handle increased traffic load. This is useful for optimizing resource allocation for web applications.

List Key Vault Secrets

az keyvault secret list --vault-name myvault --output table

Retrieve a list of secrets stored in an Azure Key Vault. Key Vault is used to securely manage sensitive information like passwords, certificates, and API keys.

List Cosmos DB Accounts

az cosmosdb list --output table

List all Cosmos DB accounts within the current subscription. Cosmos DB is a globally distributed database service that supports multiple data models.

Create an IoT Hub

az iot hub create --name myiothub --resource-group myresourcegroup --sku S1

This command creates an IoT Hub with the specified name, resource group, and SKU (S1 in this case).

List IoT Hubs

az iot hub list --output table

List all IoT Hubs within the current subscription.

Show IoT Hub Details

az iot hub show --name myiothub --resource-group myresourcegroup

Display detailed information about a specific IoT Hub.

Create an IoT Device

az iot device create --hub-name myiothub --device-id mydevice

Create an IoT device in the specified IoT Hub.

List IoT Devices

az iot device list --hub-name myiothub --output table

List all IoT devices in the specified IoT Hub.

Get IoT Device Details

az iot device show --hub-name myiothub --device-id mydevice
