Virtual Machine vs. Server: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on December 14, 2023
A virtual machine is a software emulation of a computer system, while a server is a physical or virtual system that provides services to other computers.
Key Differences
A virtual machine (VM) is a software-based emulation of a computer system, allowing multiple operating systems to run on a single physical hardware system. A server, on the other hand, is a physical or virtual system that provides resources, data, services, or programs to other computers, known as clients.
Virtual machines offer a way to partition a single physical server into multiple virtual servers, each with its own operating system and applications. In contrast, a server, whether physical or virtual, is designed to manage network resources and provide services like web hosting, data storage, or email.
The purpose of a virtual machine is to provide an isolated environment for running applications, testing, or development, replicating the functionality of a physical computer. Servers are focused on delivering continuous service and resources to client devices or other servers within a network.
Virtual machines can be quickly created, modified, or deleted, offering flexibility and efficient resource utilization. Servers, especially physical ones, require more substantial setup and maintenance, playing a critical role in the infrastructure of both local and wide area networks.
VMs are primarily software entities and rely on the underlying physical hardware of a server for their operation. Servers, whether used for hosting VMs or running applications directly, provide the essential hardware and network capabilities to facilitate various computing tasks.

Virtual Machine and Server Definitions
Virtual Machine
A virtual machine provides an isolated environment for testing applications.
Developers often use virtual machines to test new software in controlled settings.
Server
A server is a computer system that provides data, resources, or services to other computers.
Our company's website is hosted on a dedicated server.
Virtual Machine
A virtual machine is a software-based emulation of a computer system.
We use a virtual machine to run legacy software incompatible with our new systems.
Server
A server can host websites, applications, or databases for client access.
The database server handles thousands of transactions every day.
Virtual Machine
Virtual machines can simulate the functionality of separate physical computers.
The virtual machine acts like a separate computer, even though it's just software.
Server
Servers are critical for network infrastructure and continuous service delivery.
The email server processes and stores all incoming and outgoing company emails.
Virtual Machine
Virtual machines allow multiple operating systems to coexist on a single physical server.
Our IT department runs several virtual machines for different development environments.
Server
Servers manage network resources and can be physical or virtual machines.
The file server stores all our important documents and makes them accessible to employees.
Virtual Machine
A virtual machine operates on virtualized hardware resources.
We allocated more memory to the virtual machine to improve its performance.
Server
Servers often require robust hardware and maintenance to manage heavy workloads.
Upgrading our server hardware improved the speed and reliability of our network services.
Server
