What is an Azure Virtual Machine (VM)?
Updated Feb 20, 2026
Short answer
An Azure Virtual Machine is a software-based computer in the cloud that runs applications like a physical computer but is hosted on Microsoft Azure.
Deep explanation
An Azure VM is part of Infrastructure as a Service (IaaS). It allows users to create and use virtual computers without owning physical hardware.
Key features:
- Runs Windows or Linux operating systems
- Fully configurable (CPU, RAM, storage)
- Can be started, stopped, or deleted anytime
- Accessible remotely over the internet
Azure manages the physical hardware, while the user manages the operating system and installed applications.
Real-world example
A developer can create a VM in Azure to:
- Host a web application
- Run backend services
- Test software in different environments
For example, a startup can deploy their backend API on an Azure VM instead of buying a physical server.
Common mistakes
- - Thinking a VM is a physical machine
- - Assuming Azure manages everything inside the VM (user still manages OS and apps)
- - Confusing VM with App Services (they are different deployment models)
- - Forgetting VMs need security setup like firewalls and access control
