Deploying Virtual Machines on Azure
This guide provides comprehensive steps and best practices for deploying Azure Virtual Machines (VMs) to meet your computing needs. Azure VMs offer scalable, on-demand computing resources that you can deploy and manage as easily as physical servers.
1. Prerequisites
Before you begin, ensure you have the following:
- An Azure subscription. If you don't have one, create a free account.
- Permissions to create resources within your subscription.
2. Deployment Methods
You can deploy Azure VMs using various methods:
- Azure Portal: A user-friendly graphical interface for creating and managing resources.
- Azure CLI: A command-line tool for managing Azure resources.
- Azure PowerShell: Another command-line tool for managing Azure resources.
- Azure Resource Manager (ARM) Templates: Declarative templates to deploy your infrastructure as code.
This documentation will primarily focus on the Azure Portal for ease of use, with references to CLI commands.
3. Deploying a VM using the Azure Portal
Follow these steps to deploy a VM:
- Sign in to the Azure Portal: Go to portal.azure.com and sign in with your Azure account.
- Create a resource: Click the "Create a resource" button (the plus icon in the top-left corner).
- Search for Virtual Machine: In the search bar, type "Virtual machine" and select "Virtual machine" from the results.
- Click Create: On the Virtual machine page, click the "Create" button.
- Basics Tab:
- Subscription: Select your Azure subscription.
- Resource group: Choose an existing resource group or create a new one. A resource group is a logical container for your Azure resources.
- Virtual machine name: Enter a unique name for your VM.
- Region: Select the Azure region where you want to deploy your VM.
- Availability options: Choose your desired availability options (e.g., Availability Zone, Availability Set).
- Security type: Select a security type (Standard, Trusted launch, Confidential).
- Image: Select an operating system image (e.g., Windows Server, Ubuntu Server).
- Size: Choose a VM size based on your performance and cost requirements.
- Administrator account:
- Authentication type: Select SSH public key or Password.
- Username: Enter a username for the administrator.
- Password/SSH public key: Provide your credentials.
- Inbound port rules: Select public inbound ports to allow (e.g., RDP for Windows, SSH for Linux).
- Disks Tab: Configure your VM's storage. You can choose the OS disk type (e.g., Premium SSD, Standard SSD, Standard HDD) and add data disks if needed.
- Networking Tab: Configure the virtual network, subnet, public IP address, and network security group (NSG) for your VM. You can create new ones or use existing resources.
- Management, Advanced, Tags Tabs: Review and configure other settings such as monitoring, auto-shutdown, extensions, and tags as per your requirements.
- Review + create: Once all configurations are complete, click "Review + create". Azure will validate your settings.
- Create: If validation passes, click "Create" to start the deployment.
4. Deploying a VM using Azure CLI
Here's a basic example of deploying a Linux VM using Azure CLI:
az vm create \
--resource-group MyResourceGroup \
--name MyVM \
--image UbuntuLTS \
--admin-username azureuser \
--generate-ssh-keys
This command creates a VM named MyVM in the MyResourceGroup using the latest Ubuntu LTS image and generates an SSH key pair for authentication.
For Windows VMs, you would typically use a password:
az vm create \
--resource-group MyResourceGroup \
--name MyWinVM \
--image Win2019Datacenter \
--admin-username azureuser \
--admin-password YourSecurePassword123!
Note: Replace MyResourceGroup, MyVM, MyWinVM, and credentials with your desired values.
5. Connecting to your VM
After deployment, you can connect to your VM:
- Linux VMs: Use SSH. You'll need the VM's public IP address.
ssh azureuser@ - Windows VMs: Use Remote Desktop Protocol (RDP). You can download the RDP file from the Azure portal.
