Server virtualization is the technology of separating a physical server into multiple virtual servers. Each virtual instant is completely isolated from the others and can run its own operating system and processes independently.
Using a hypervisor, the server’s hardware is isolated from its software, allowing users to access the resources remotely.

Server Virtualization Features
At its core, server virtualization allows a single server to run and operate like it’s a collection of individual servers. The virtualization technique used can result in different features and capabilities in the virtual server.
There are three types of server virtualization:
OS-level server virtualization is the most basic form. By partitioning the OS, the server could include multiple virtual machines (VMs) without needing hypervisor software.
While requiring the least amount of resources, OS-level server virtualization would result in all segments using the same OS.
Para-virtualization allows the addition of guest OS inside the virtual machine. In this method, all systems can communicate and work together as a network and share resources, without needing each one to emulate the entirety of the hardware environment.
Requiring a hypervisor, para-virtualization demands fewer physical resources individually.
Full server virtualization requires the use of hypervisor software to monitor and distribute CPU and disk space usage among individual virtual servers.
With full virtualization, individual servers operate as independent machines, unaware of each other and capable of using a different OS.
Server virtualization has numerous applications, depending on the capabilities the type offers.
DevOps and Testing
VMs can be used for testing software builds compatibility without fear of damaging systems. It can also be used to test and optimize security and communication solutions between individual VMs, reducing downtime and redundancy.
VMs on servers allow for live data migration and easy movement between physical servers, without risking service downtime or disturbances.
Server virtualization allows for the simultaneous access and use of multiple operating systems on the same hardware. Multi-platform support would increase software options and boost business and operations functionality.
Benefits of Server Virtualization
Virtualization in general, and server virtualization in particular, allows you to use a piece of hardware to its full potential. It’s a cost-efficient approach to expanding an IT infrastructure and using it for multiple purposes simultaneously.
A few notable benefits of server virtualization include:
- Reduces IT operating costs
- Increases hardware efficiency and productivity
- Reduces downtime
- Reduces the overall number of physical servers
- Increases server resiliency
- Optimizes hardware resources
- Creates independent user environments
Server Virtualization Use Cases
See below how server virtualization is being used by organizations in different industries.
Trace One is a technology company and provider of networking services used in developing reliable and secure label products. Based in France, Trace One employs over 100 professionals in serving 20,000 companies in more than 100 countries.
Improving the infrastructure was a critical part of Trace One’s evolution and growth in the industry. However, the firm’s IT team was running into problems with the U.S. server, losing connectivity with global team members.
Working with Google Cloud and its partner, Cloudreach, Trace One decided on moving its U.S. server data to Google Compute Engine, removing unnecessary physical servers.
“We use Compute Engine for professional service environments. The team can create environments on-demand and in parallel, which we couldn’t do in the past due to cost and performance issues. Now we can create services in a click, closing the server overnight to control the cost,” says Junaid Ansari, head of infrastructure, Trace One.
“As part of the migration, with the help of Cloudreach, we were able to optimize and remove unnecessary servers.”
Moving to virtual CPUs, Trace One was able to improve system reliability and scale up to meet the demand at its peak.
Vitec AutoData is a provider of hosted and managed IT solutions and services that covers the billing, payment, and accounting processes. Based in Oslo, Norway, it mainly services wholesalers and retailers of automotive parts and vehicle components.
As Vitec AutoData expanded, its customers were demanding a more reliable and efficient way to connect with the company’s platform and access its services.
Building a virtual server with IBM, Vitec AutoData was able to migrate its core functionalities to IBM’s mainframe and offers its customer an accessible and high-performance platform.
“Building a virtualized server farm with SUSE Linux Enterprise Server on the IBM System z13s provides us with a scalable and cost-effective solution. … With IBM z Systems, we can ensure 24/7 always-on availability, incredibly high reliability, and super-high performance,” says Geir Erland Fladby, system administrator, Vitec AutoData.
Working with IBM, Vitec AutoData was able to drastically reduce the cost of its IT infrastructure, strengthen its security and reliability, and ensure a simple onboarding process for new clients.
