Creating and Configuring Azure Linux Virtual Machine
Creating a new Azure Linux Virtual Machine (VM) is a straightforward process that can be completed using the Azure portal, Azure CLI, or Terraform. Azure provides a wide range of Linux distributions to choose from, making it easy to select the best operating system for your needs.
Creating a New Azure Linux Virtual Machine
To create a new Azure Linux Virtual Machine, follow these steps:
* Log in to the Azure portal and navigate to the virtual machines section.
* Click on the “Create a virtual machine” button.
* Choose a Linux distribution from the list of available options.
* Select the desired Azure region and resource group.
* Choose the desired size and type of virtual machine.
* Configure the virtual machine’s network settings, security group, and storage.
* Review and create the virtual machine.
Configuring Network Settings
Configuring the network settings for your Azure Linux Virtual Machine is crucial for ensuring that it can communicate with other resources on the network. The following are some key considerations when configuring network settings:
*
Virtual Network (VNet)
Virtual Networks (VNets) are a fundamental component of Azure Networking. To create an Azure Linux Virtual Machine, you must first configure a VNet. This will allow you to assign a private IP address to the VM and define network security groups that manage traffic in and out of the VM.
*
Subnet
A subnet is a subset of an Azure Virtual Network that isolates traffic for a specific application or workload. Configure the subnet size to ensure that your virtual machine has sufficient IP addresses.
*
Public IP Address
If your application requires a public IP address to communicate with users, you can assign one during VM creation. You can use Static Public IP address to assign it to a specific resource and make your resource more available and accessible.
*
Network Interface
Network interfaces are virtual network interfaces that you can associate with your Azure Linux Virtual Machine. Each virtual network interface represents a layer 2 (Ethernet) connection from your virtual machine to the network.

This includes monitoring resource usage, configuring networking and storage, and automating tasks using scripts and tools. In this section, we will explore how to use Azure CLI and Azure SDKs to manage Azure Linux Virtual Machines and automate management tasks.
Managing Azure Linux Virtual Machine with Azure CLI, Azurerm_linux_virtual_machine
The Azure CLI is a command-line tool for managing Azure resources, including virtual machines. To use Azure CLI to manage your Azure Linux Virtual Machine, follow these steps:
Step 1: Install Azure CLI
Install the Azure CLI using pip: `pip install azure-cli`
Step 2: Configure Azure CLI
Configure the Azure CLI using the command `az configure`.
Step 3: List Virtual Machines
List your virtual machines using the command `az vm list`.

Azure SDKs provide a programming interface for integrating Azure services with your applications. To use Azure SDKs to manage your Azure Linux Virtual Machine, follow these steps:
Step 1: Install Azure SDKs
Install the Azure SDKs using pip: `pip install azure-mgmt-compute`
Step 2: Configure Azure SDKs
Configure the Azure SDKs using the Azure CLI: `az configure`
Step 3: Create Virtual Machines
Create a virtual machine using the Azure SDKs: `vm = compute_client.virtual_machines.create_or_update(resource_group.name, vm_resource, parameters)`
Step 4: Update Virtual Machines
Update a virtual machine using the Azure SDKs: `vm = compute_client.virtual_machines.update(resource_group.name, vm_resource, parameters)`
Automating Azure Linux Virtual Machine Management Tasks
Automating Azure Linux Virtual Machine management tasks can save time and reduce the risk of human error. Here are some tasks that can be automated:
- Stop or start virtual machines based on a schedule
- Update virtual machine configurations automatically
- Monitor virtual machine resource usage and alert on thresholds
- Automate backups and restore virtual machines
Designing a Custom Script to Automate Azure Linux Virtual Machine Management Tasks
Designing a custom script to automate Azure Linux Virtual Machine management tasks requires a deep understanding of Azure services and scripting languages. Here is an example script that can be used to automate the stop or start of virtual machines based on a schedule:
Python Script: Automate Virtual Machine Stop or Start
“`python
import datetime
import time
from azure.mgmt.compute import ComputeManagementClient
from azure.common.credentials import ServicePrincipalCredentials
# Import the necessary libraries
# Define the credentials for the Service Principal
credentials = ServicePrincipalCredentials(
client_id=’your_client_id’,
client_secret=’your_client_secret’,
tenant=’your_tenant’
)
# Create a Compute Management client
compute_client = ComputeManagementClient(credentials, ‘your_subscription_id’)
# Define the resource group and virtual machine name
resource_group_name = ‘your_resource_group_name’
vm_name = ‘your_vm_name’
# Define the schedule for stopping or starting the virtual machine
schedule_interval = datetime.timedelta(minutes=30)
# Loop indefinitely
while True:
# Get the current datetime
current_datetime = datetime.datetime.now()
# Check if the current datetime is within the schedule interval
if current_datetime.minute % schedule_interval.minutes == 0:
# Start or stop the virtual machine based on the current datetime
if current_datetime.hour % 2 == 0:
# Stop the virtual machine
result = compute_client.virtual_machines.stop(resource_group_name, vm_name)
else:
# Start the virtual machine
result = compute_client.virtual_machines.start(resource_group_name, vm_name)
# Print the result
print(result)
# Sleep for 1 minute
time.sleep(60)
“`
This script uses the Azure Python SDK to automate the stop or start of virtual machines based on a schedule. The script defines the schedule interval and loops indefinitely, checking the current datetime against the schedule interval. If the current datetime is within the schedule interval, the script starts or stops the virtual machine based on the current hour.
This script is just an example and can be modified to suit your specific requirements. Additionally, it is recommended to use environment variables to store sensitive information such as client secrets and passwords.

Cost Optimization for Azure Linux Virtual Machine
Cost optimization for Azure Linux Virtual Machine is a crucial aspect of cloud computing. It involves analyzing and reducing the costs associated with deploying and running Linux virtual machines on the Azure platform. Effective cost optimization can help organizations save money on infrastructure, reduce waste, and improve resource utilization.
Calculating the Cost of Azure Linux Virtual Machine
The cost of an Azure Linux Virtual Machine is calculated based on several factors, including the virtual machine’s size, operating system, and usage. The cost can be broken down into two main components: compute and storage. The compute cost is based on the virtual machine’s size, with larger machines costing more per hour. The storage cost is based on the amount of data stored, with prices ranging from $0.0225 to $0.0675 per GB per month.
Cost = (Compute Cost + Storage Cost) x Usage
For example, let’s say we have a virtual machine with a size of Standard_DS4_v2, which costs $0.1028 per hour for the first 750 hours. If we use this machine for 1000 hours, the compute cost would be $0.1028 x 750 = $77.1. If we also store 50 GB of data, the storage cost would be $0.0225 x 50 = $1.125. The total cost would be $77.1 + $1.125 = $78.225.
Ways to Optimize Azure Linux Virtual Machine Costs
There are several ways to optimize Azure Linux Virtual Machine costs. Some of the most effective strategies include:
- Right-sizing virtual machines: This involves selecting the correct size of virtual machine for your workload, based on performance and cost considerations.
- Migrating workloads to lower-cost instances: If you have workloads that can run on lower-cost instances, such as Azure Spot VMs, you can save money by migrating them to these instances.
- Using Reserved VM Instances: Reserved VM Instances allow you to reserve capacity in advance for a one- or three-year term in exchange for a discounted price.
- Optimizing storage usage: By optimizing storage usage, you can reduce storage costs and save money on your virtual machine bill.
Cost Optimization Strategies for Azure Linux Virtual Machine
Here are some cost optimization strategies for Azure Linux Virtual Machine:
