Azure VMs

💡 What is an Azure Virtual Machine?¶

A VM in Azure lets you run applications on a virtualized environment with full control over the OS, compute, and networking.

🧱 Core Components of an Azure VM¶

Component	Description
Image	OS template like Ubuntu or Windows
Size	CPU, RAM, Disk performance level
OS Disk	Main boot disk
Data Disk	Additional storage (optional)
VNet + Subnet	Networking infrastructure
NIC	Network Interface Card
Public IP	Optional external access
NSG	Network Security Group (firewall rules)

⚙️ Steps to Create an Azure VM (via Portal)¶

[Refer to earlier steps in original message]

🧑‍💻 Connect to Your VM¶

Linux: ssh <user>@<public-ip>
Windows: Use Remote Desktop Connection (RDP)

💻 Create Azure VM with Terraform (Only VM Block)¶

resource "azurerm_linux_virtual_machine" "vm" {
  name                = "myVM"
  resource_group_name = azurerm_resource_group.rg.name
  location            = azurerm_resource_group.rg.location
  size                = "Standard_B1s"
  admin_username      = "azureuser"
  network_interface_ids = [azurerm_network_interface.nic.id]

  admin_ssh_key {
    username   = "azureuser"
    public_key = file("~/.ssh/id_rsa.pub")
  }

  os_disk {
    caching              = "ReadWrite"
    storage_account_type = "Standard_LRS"
    name                 = "myOsDisk"
  }

  source_image_reference {
    publisher = "Canonical"
    offer     = "UbuntuServer"
    sku       = "22_04-lts"
    version   = "latest"
  }
}
