Azure VM Setup

Create and manage VMs.

Introduction

Azure Virtual Machines allow you to run computing workloads in the cloud. Learn setup, configuration, and management.

Description

Azure Virtual Machines (VMs) provide on-demand, scalable computing resources. They allow you to deploy applications, run workloads, and host services without managing physical servers.

Main Content

### What are Azure Virtual Machines? Azure VMs are scalable computing resources that can run Windows, Linux, or other operating systems. They provide full control over the OS, storage, and networking configurations. ### Steps to Create an Azure VM 1. **Sign in to Azure Portal** – Navigate to 'Virtual Machines' and click 'Create'. 2. **Choose Image & Size** – Select the OS (Windows/Linux) and VM size (CPU, RAM) according to workload. 3. **Configure Settings** – Set VM name, region, and availability options. 4. **Networking** – Configure virtual network, subnet, and public IP. 5. **Authentication** – Choose SSH keys (Linux) or username/password (Windows). 6. **Disks & Storage** – Select OS disk type and attach data disks if needed. 7. **Review and Create** – Validate settings and deploy the VM. ### VM Management - **Start/Stop/Restart** – Control VM lifecycle. - **Scaling** – Adjust resources or use Virtual Machine Scale Sets. - **Monitoring** – Use Azure Monitor and diagnostics for performance and logs. - **Security** – Configure NSGs, firewalls, and enable backup/DR options. ### Best Practices - Use managed disks for reliability. - Enable monitoring and alerts. - Apply security best practices like patching and least-privilege access. - Choose the right VM size to optimize cost and performance.

Conclusion

Azure Virtual Machines offer flexible and scalable computing resources for a variety of workloads. Proper configuration, security, and monitoring are key to leveraging VMs effectively in the cloud.
