A virtual server, a virtual machine (VM), is a software-based computing model that takes the form of a physical computer. It operates within a host system stimulated by virtualization software or hypervisors like Microsoft Hyper-V, VMware, or Oracle VirtualBox.

Unlike a physical server, which dedicates its complete hardware to its processes, a virtual server shares its host’s resources like memory, CPU, and storage. At the same time, other VMs run on the same physical machine.

This architecture enables multiple virtual servers to operate simultaneously on a single physical server, each boosting its own applications, operating system, and isolated environments. The main benefit of virtual servers is their ability to deliver flexibility, scalability, and resource optimization, as they can be easily created, modified, migrated, or deleted based on evolving needs.

Common Types of Virtual Servers

Common Types of Virtual Servers

Below are some of the most common types of virtual servers:

Hypervisor-based Virtual Servers (Type 1)

  • VMware vSphere/ESXi: Widely used in enterprises, offering advanced features and robust performance.
  • Microsoft Hyper-V: Integrated into Windows Server editions, it’s a popular choice for Windows-centric organizations.
  • Oracle VM Server for x86: A free-to-use virtualization solution that supports a range of guest OSes.
  • Xen: An open-source hypervisor many cloud providers use, including Amazon Web Services (for its Amazon EC2 service).

Hosted Virtual Servers (Type 2)

  • Hosted Hypervisors: These run within a conventional operating system environment. Examples include:
  • VMware Workstation: Suitable for desktop environments, it allows users to run multiple OSes on a single workstation.
  • Oracle VirtualBox: A free and open-source solution, ideal for desktop users wanting to run multiple OSes.
  • Parallels Desktop: Popular among Mac users, it allows running Windows, Linux, or other OSes alongside macOS.

Para-virtualization Servers

Instead of emulating complete hardware, para-virtualization involves a software interface closely resembling the underlying hardware but requires OSes to be modified for this environment. The Xen hypervisor supports para-virtualization.

Containers

Containers virtualize the OS instead of the underlying physical hardware. This allows multiple workloads to share a single OS instance. Examples include:

  • Docker: A popular container-based virtualization platform known for its efficiency and scalability.
  • LXC: Linux Containers provide a lightweight environment for running multiple isolated Linux systems (containers) on a single Linux control host.

  • Azure Virtual Machines: Part of Microsoft’s Azure platform – users can deploy various computing solutions.

How Does a Virtual Server Work?

How Does a Virtual Server Work

Below is a breakdown of how a virtual server works:

Hypervisor

The hypervisor is at the heart of virtualization. This is a software layer (or, in some cases, an amalgamation of hardware and software) between the server’s hardware and its operating system. The hypervisor creates, manages, and runs virtual machines (VMs).

Virtual Machines (VMs)

Each VM is an independent environment with virtual hardware resources (CPU, RAM, storage, etc.) allocated from the physical server’s resources. It can run its own operating system independently of the physical server’s underlying ‘host’ operating system.

Resource Allocation

The hypervisor dynamically allocates the physical server’s resources to the VMs based on configuration and need. For example, a physical server with 32 GB of RAM might host four VMs, each with 8 GB of allocated virtual RAM.

Isolation

One of the top benefits of virtual servers is their isolation. The actions or failures within one VM don’t impact others. This is crucial for maintaining a stable environment, especially when hosting different applications or services on separate VMs.

Snapshot and Migration

Virtual servers can be ‘snapshotted’ to capture their current state, allowing quick backups, testing, or system rollbacks. VMs can be migrated between physical servers with minimal downtime, offering flexibility and ease of management.

Overhead Management

While the hypervisor introduces some level of overhead, advancements in virtualization technology and hardware acceleration features have significantly reduced this impact. This empowers VMs to achieve near-native performance.

Network Virtualization

Virtual servers can also have virtual network interfaces, switches, and routers. This allows for complex network configurations and connections within and between VMs without physical networking hardware.
