Azure Key Vault

Overview

Azure Key Vault safeguards cryptographic keys, secrets, and certificates used by cloud applications and services.

Real-life Use Cases

• Cloud Architect: Centralize secrets management for microservices.
• DevOps Engineer: Automate secret rotation in CI/CD pipelines.

Terraform Example

resource "azurerm_key_vault" "main" {
  name                        = "my-keyvault"
  location                    = azurerm_resource_group.main.location
  resource_group_name         = azurerm_resource_group.main.name
  tenant_id                   = data.azurerm_client_config.current.tenant_id
  sku_name                    = "standard"
}

Bicep Example

resource keyVault 'Microsoft.KeyVault/vaults@2022-07-01' = {
  name: 'my-keyvault'
  location: resourceGroup().location
  properties: {
    tenantId: subscription().tenantId
    sku: {
      family: 'A'
      name: 'standard'
    }
    accessPolicies: []
  }
}

Azure CLI Example

az keyvault create --name my-keyvault --resource-group my-rg --location westeurope

Best Practices

• Enable soft-delete and purge protection.
• Use RBAC for access control.

Common Pitfalls

• Storing secrets in code.
• Not monitoring access logs.

Joke: Why did the secret leave Key Vault? It couldn’t handle the pressure!
