Azure is a cloud computing platform offered by Microsoft that provides a wide range of services, including virtual machines (VMs). In this blog post, we will discuss deploying virtual machines in Azure. We will cover the basics of Azure VMs, how to create and manage VMs, and best practices for deploying VMs in Azure.


Azure Virtual Machines Overview


Azure VMs provide on-demand computing resources that can be used to run applications, workloads, and services in the cloud. VMs are a scalable and flexible solution for businesses that need to run applications in the cloud, without having to manage the underlying infrastructure.

Azure VMs come in different sizes and configurations, allowing businesses to choose the resources that best suit their needs. VM sizes are measured in terms of virtual CPUs, memory, and storage capacity. Azure offers a wide range of VM sizes, from small instances with one virtual CPU and 0.75 GB of memory to large instances with 416 virtual CPUs and 12 TB of memory.

Azure VMs also support different operating systems, including Windows Server, Linux, and other open-source operating systems. This flexibility allows businesses to choose the operating system that best fits their needs.


Creating a Virtual Machine in Azure


Creating a virtual machine in Azure is a straightforward process. Here are the steps to create a VM in Azure:


1. Sign in to the Azure portal.

2. Click on the "Create a resource" button in the upper-left corner of the Azure portal.

3. In the search box, type "Windows Server" or "Linux" and select the appropriate operating system.

4. Select the desired VM size from the list of available options.

5. Choose a subscription and resource group for the VM.

6. Enter a name for the VM.

7. Choose a region where the VM will be deployed.

8. Enter a username and password for the VM.

9. Select the appropriate networking options, such as virtual network and subnet.

10. Click on the "Review + create" button to review the VM settings.

11. Click on the "Create" button to create the VM.

Once the VM is created, you can connect to it using remote desktop or SSH. You can also install and configure software on the VM, such as web servers, databases, and other applications.


Managing Virtual Machines in Azure

Managing virtual machines in Azure involves performing various tasks, such as monitoring, scaling, and updating VMs. Here are some of the common management tasks for VMs in Azure:


Monitoring: Azure provides various tools and services for monitoring VMs, such as Azure Monitor, Azure Log Analytics, and Azure Application Insights. These tools allow businesses to monitor VM performance, availability, and security.


Scaling: Azure VMs can be scaled vertically or horizontally. Vertical scaling involves increasing or decreasing the size of the VM, while horizontal scaling involves adding or removing VM instances. Azure provides various tools and services for scaling VMs, such as Azure Virtual Machine Scale Sets, Azure Load Balancer, and Azure Application Gateway.


Updating: Azure VMs need to be updated regularly to ensure they are running the latest software and security patches. Azure provides various tools and services for updating VMs, such as Azure Update Management and Azure Automation.


Best Practices for Deploying Virtual Machines in Azure


Here are some best practices for deploying virtual machines in Azure:


Choose the right VM size: Choose a VM size that meets your application requirements, but avoid oversizing or undersizing VMs. Oversized VMs can result in unnecessary costs, while undersized VMs can lead to poor performance.


Use managed disks: Managed disks are a recommended storage option for VMs in Azure. They offer better performance, reliability, and scalability compared to unmanaged disks.


Use Azure Availability Sets: Azure Availability Sets provide high availability and resiliency for VMs by distributing them across multiple physical servers, racks, and update domains. This ensures that if one physical server or rack goes down, the VMs will be automatically moved to another physical server or rack, minimizing downtime.


Use Azure Virtual Network: Azure Virtual Network allows businesses to create isolated networks for their VMs, ensuring that they are not accessible from the public internet. This improves security and reduces the risk of attacks.


Use Azure Backup: Azure Backup provides a reliable and cost-effective backup solution for VMs in Azure. It allows businesses to back up and restore VMs, ensuring that their data is protected against data loss and disasters.


Use Azure Security Center: Azure Security Center provides advanced threat protection and security management for VMs in Azure. It allows businesses to monitor and detect security threats, and provides recommendations for improving security.


Use Azure Reserved Instances: Azure Reserved Instances allow businesses to save money on VMs by committing to a one-year or three-year term. This provides significant discounts on VM prices, compared to on-demand pricing.




Deploying virtual machines in Azure is a simple and flexible solution for businesses that need to run applications in the cloud. Azure VMs provide on-demand computing resources that can be scaled up or down as needed, and support different operating systems and configurations. By following best practices for deploying VMs in Azure, businesses can ensure that their VMs are secure, highly available, and cost-effective.
