VMware technologies are a collection of software and solutions that lets you run numerous operating systems(OS)—or “virtual machines”—on a single piece of hardware.
It offers cloud-based software and virtualization solutions to its 500,000 customers worldwide to facilitate digital innovation and safeguard businesses’ data.
In VMware server virtualization, a hypervisor is placed on the physical server to operate many virtual machines (VMs) simultaneously.
As each virtual machine can run its own OS, a single physical server can host numerous OSes simultaneously.

Virtual Machines – Base Unit of VMware Virtualization
A virtual machine (VM) is the fundamental building block of VMware virtualization. A visitor operating system is a software-based simulation of a physical computer running in a virtual machine.
VMware offers a variety of file management utilities, including vSphere Client. This command-line interface for virtual machine administration enables the configuration of virtual machine parameters.
Users can choose from two types of Virtual machines—process VMs and system VMs:
1. Process Virtual Machine
Provides a platform-independent development environment by masking the hardware or operating system details, allowing a single process to act as an application on a host machine.
Example: Java Virtual Machine allowing Java programs to run on any OS.
2. System Virtual Machine
Completely virtualizes to replace a physical machine. A system platform enables sharing of material resources of a host computer among multiple virtual machines, each of which runs its copy of the operating system.
Example: Utilizes a hypervisor, which can operate on isolated hardware, such as VMware ESXi, or on top of an operating system.
Learn the different products of VMware and how it functions through the following details.
VMware Products – Offering a Range of Programs
VMware provides vast software and hardware, enabling robust cloud computing and virtualization infrastructure.
Many different products cover—depending on your requirements—apps, the cloud, networking, workspace, security, and more.
Find out what these VMware products are and how they manage your IT infrastructure through the following details.
1. Hypervisors – Hosting Various VMs
A hypervisor, a Virtual Machine Monitor (VMM), allows a server to host numerous virtual machines and operating systems.
A “host machine” is the server where the hypervisor runs one or more virtual computers. On the other hand, a “guest machine” refers to each VM.
Hypervisors are responsible for isolating the virtual machine’s resources from the hardware system and distributing them appropriately.
Using hypervisors reduces hardware costs and improves cloud accessibility and scalability, enabling cloud migration.
There are two types of Hypervisors – Bare-metal or Native Hypervisors and Hosted or Client hypervisors. Their functionality and examples are stated in the table below.
| Bare-metal or Native Hypervisors | Hosted or Client hypervisors | |
| Functionality | It runs directly on the server Manages guest operating system | Operates as a software layer on top of the host machine’s operating system. |
| Examples: | KVM Proxmox Hyper-V VMware ESXi | EQEMU VirtualBox. Parallels Desktop VMware Fusion. |
2. vSphere – Administering Multiple Hypervisors
VMware vSphere is VMware’s enterprise virtualization platform, which includes the ESXi hypervisor software and the vCenter Server management platform for administering multiple hypervisors.

Virtual SAN offers predictable scalability and all-flash performance at a fraction of the cost of purpose-built storage arrays.
Like vSphere, Virtual SAN lets users choose from a wide range of hardware and deploy and manage it for different IT workloads and use cases.
6.Cloud Management – Organizing Different Workloads
Cloud Management is the monitoring and optimization of the utilization of one or more private or public clouds. Typically, organizations use a cloud management platform to oversee cloud usage.
Cloud administration enables IT administrators to distribute workloads across multiple clouds and control the cost of cloud resources.
Source: VMware
Cloud management platforms may manage data, content, or applications in the cloud or all three. These are:
- Data management: Backing up data in the cloud is often part of a disaster recovery strategy. Cloud management tools allow this process to be automated.
- Content management: Using different clouds to host content that has additional requirements for accessibility. This can save costs when rarely needed archived content is stored in a low-cost cloud with higher latency.
- Application management: Allows organizations to monitor cloud-native applications and quickly scale up processing or storage resources when necessary.
NSX Networking – Leveraging Network Security
The VMware NSX network virtualization platform enables the creation of secure virtual networks on top of an existing physical network and virtual server infrastructure.
NSX utilizes Software-Defined Networking (SDN) to programmatically define virtual networks on demand, regardless of the underlying hardware in your infrastructure.
When you need to increase the capacity of your network, you can configure a second virtual network or reconfigure an existing one instead of purchasing additional hardware.
Furthermore, VMWare NSX provides the following features and benefits:
- Network automation – Automatic deployment and network infrastructure configuration using code, adaptable to specific requirements, and allowing virtual component addition as needed.
- Multi-cloud and on-premises support – Virtual networks appear the same regardless of where they are deployed, making them easier to support.
- Network segmentation – Virtual networks are divided into segments that are separate from each other. Any adverse impact from an attack against the network is contained within the affected segment.
- Minimal cost and resource overhead – With networking and security implemented via software, the acquisition, and maintenance of expensive network equipment are no longer needed.
- Switching and routing – These are all done via code and with applications and virtual machines also logically attached to the network. Virtual networks feature scale-out routing with an active-active failover system.
- Load balancing – These are packet-based or socket-based, with an L4 load-balancer using the former and an L7 load-balancer responsible for the latter.
Workspace ONE – Transmits Application to Devices
VMware Workspace ONE is a platform that transmits and manages any application on any device by integrating the following,
- access control

FAQs
What is VMware Virtualization?
VMware server virtualization is a method used for turning a single physical server into a group of virtual servers that operate as their own. Each functions as a VMware virtual machine but essentially shares the resources of the main machine.
Moreover, each virtual machine can run its own VMware operating system. VMware virtualization uses a hypervisor to create a virtual environment—efficiently distributing RAM and other resources across various virtual machines.
VMware supports a hypervisor to run containerized workloads in a Kubernetes cluster. The solution is ideal for users who want to separate each VMware virtual platform for different projects and other purposes.What is VMware used for?
So what is VMware used for? Although the VMware platform creates virtual machines and cloud computing solutions, it can be used for several applications. Key benefits include enabling seamless scalability, network flexibility, automated operations, remote workforces, and better security—all of which businesses can use to cut costs.
How does VMware Work?
What does VMware do? In simple terms, it takes a single computer and creates multiple virtual computers that share the original’s resources.
Imagine that your desktop Windows PC uses VMware on a single home-user basis. You could operate two or three other Windows environments, which function like two or three separate PCs. The only difference is that they’re reliant on the underlying hardware of the original physical system.Is VMware an Operating System?
No. VMware is not commonly considered an operating system. But with virtualization, VMware hypervisor users can install multiple operating systems—one for each virtual server. These include various OS options—from Windows Vista to Windows 10, alongside Windows Server editions 2007 SP2. There are also options for CentOS, Linux, and Ubuntu for those who shun Microsoft.
And vSphere (formerly VMware ESXi)—based on the VMkernel operating system—is a hypervisor that functions on the machine without requiring any other standard or VMware operating systems.
