Physical server Vs Virtual Server | Difference | Comparison

Both virtual and physical servers are dependable options that meet the needs of various use cases and businesses. So let us check out the difference between physical server and virtual server to better understand this topic.

What is a Virtual Server?

A software computer that duplicates a real, physical computer is called a virtual machine(VM). Multiple virtual machines (VMs) share physical hardware in an environment known as multi-tenant operation for virtual servers. In this instance, all virtual machines operating on a real server share their computing power. A virtual server architecture is slightly more complex than a real server.  Thus actual hardware is put on top of a hypervisor, such as Microsoft Hyper-V or VMware vSphere. 

What is a Physical Server?

Hardware is referred to as a physical server. With its motherboard, CPU, memory, and other components, it is a recognizable computer. Physical servers, also called bare metal servers, contain no space between the operating system and the actual hardware. A physical server can run Windows, Linux, or any other unique operating system, but it can only run one operating system at a time.

Physical Server Vs Virtual Server | Difference

Cost

In physical server hardware purchase, maintance and replacement make it relatively costly as compared to Virtual machines. While in a Virtual server is no upfront cost. Software testing and maintance costs are relatively lower.

Space requirement

Every physical component of hardware is shared by a single server. As a result, the virtual server needs less space. On the other hand, Physical servers require larger space since they must hold separate physical hardware elements, such as the CPU, Memory, and storage.

Performance

One major difference is Physical servers are more powerful and efficient overall because they have specialized resources such as CPU, Memory, and network components. While in virtual servers are less efficient than physical servers since virtual servers are multitenant systems that share physical hardware resources around multiple users.

Security

Security management is simplified in a virtual environment as opposed to the complexity of physical servers. Depending on its resources and the kind of data it maintains security systems need to be set up for every physical server.

Implementation and Migration

Physical server is migration from one physical server to another is difficult and complex, while in Virtual server can be seamlessly moved across the virtualized environment and even from one physical server to another.

Control

24/7 access and complete control over the physical server and applications. However, the virtual server has less control over the host server and the applications that run on it.

Scalability

Physical server scalability can be difficult because extra hardware components are required. A virtual server environment, on the other hand, provides more scalability. 

Portability

The relocation of physical servers, on the other hand, it is a difficult task. In entails transferring all hardware and data to the new server location, then reinstalling hardware and software on the newly acquired server

Workload relocation in the virtual environment is a smooth process that makes it easy to switch between actual hardware platforms. Moreover, the online execution of this migration ensures continuous operations.
