Businesses are redefining IT management standards in 2024.
Consider a large company that has reduced the footprint of its data centers by seventy percent through Server Virtualization. This technology is undoubtedly revolutionizing how businesses manage resources, boost efficiency, and adapt in an increasingly digital world to stay competitive. It is a cost-effective way to provide web hosting services and effectively utilize existing resources in IT infrastructure.
It sounds easy right? Well to know if it is that simple you’ll have to read through the whole Article.
Before jumping into further details on our topic, Here’s a quick background for you on what Servers are.
Servers are the backbone of technology. They are software or hardware devices that handle, store, and process data as well as provide services to other computers connected to a network a single operating system and a certain set of programs are installed on each physical server, which results in insufficient use of resources and increased expenses.
Here’s an example to make it simple: A user can set up a server, for instance, to handle print jobs, send and receive email, host a website, and restrict network access.

Understanding Server Virtualization?
Now, the main focus of our discussion today is server virtualization and its key concepts.
Everything changed with the introduction of server virtualization.
In the past, computer hardware and software worked as a resource-conscious processing power designed to support only one application at a time, leading to inefficiencies and increased demands on resources as businesses expanded their use of applications and services.
The process of separating a physical server using software into several distinct and isolated virtual servers is known as server virtualization where each virtual Server can operate independently from its operating system.
Server virtualization is the underlying basis for cloud computing and enables various hybrid cloud models. A company can maximize its complete infrastructure’s processing, storage, and networking resources while using or offering web hosting services at a reasonable cost.
Types Of Server Virtualization
Here are 4 Server Virtualization types you should know about.
The hypervisor
Between the operating system and the hardware, there is a layer known as a hypervisor or VMM (virtual machine monitor). It offers the features and services required to efficiently operate several operating systems. The hypervisor treats resources like CPU, memory, and storage as a pool that can be easily reallocated between existing guests or to new virtual machines.
In addition to handling the queuing, dispatching, and returning of the hardware requests, it recognizes traps and responds to privileged CPU instructions. The hypervisor is topped by a host operating system that controls and manages the virtual devices.
Hypervisor has Further 2 Types:
Type 1 Hypervisors (Bare-Metal): Operates without the need for a major operating system, directly on the host computer’s physical hardware. It controls guest operating systems through direct hardware interaction. Due to its efficiency and performance, this type is frequently used in enterprise settings.
Examples: VMware vSphere/ESXi, Microsoft Hyper-V, and Xen (used by AWS for its EC2 service).
Type 2 Hypervisors (Hosted): It is an application or software layer on a traditional operating system, that separates the host and guest operating systems for scheduling virtual machine resources.
Example: VMware Workstation, Oracle VirtualBox, Parallels Desktop (for Mac).
Para-virtualization
Para-virtualization is another Server Virtualization type, the servers in also utilize a hypervisor, but they do not perfectly replicate the hardware of the physical host. Instead, an API, typically integrated into modern servers, directly interacts with the operating systems of the host and virtual servers. As a result, the virtual servers recognize the resources of the host and other virtual servers as an extension of their own.
Involves the entire network working together as a cohesive unit. Since each operating system on the virtual servers is aware of one another in para-virtualization, the hypervisor requires less processing power to manage the entire system because the VMs handle it well. The virtual machines (VMs) on the host server are not isolated from each other. They can interact over the network despite their relative independence.
Today, para-virtualization is less commonly used as servers are now being designed to more effectively support and work with bare-metal hypervisors.
Example: Amazon EC2 and Xen.
Kernel level Virtualization
Kernel Level Virtualization is another type of Server Virtualization system that operates a different Linux kernel and perceives the linked virtual machine as a user-space process on the physical host, doing away with the need for a hypervisor.
Running several virtual machines on a single host is made simple by this. The virtual machine and the main Linux kernel communicate via a device driver.
Virtualization requires processor support (AMD – v or Intel VT).
The virtual machines’ execution and display containers are slightly modified QEMU processes. Kernel-level virtualization can be thought of as a more advanced version of server virtualization.
OS-Level Virtualization
This Server Virtualization type enables the use of multiple virtual environments without the need for a hypervisor. This type of virtualization, also known as “containerization,” utilizes the virtualization capabilities of the host operating system as the hypervisor. Processing takes place within each server’s “container” or virtual environment and is limited by the available resources.
For this virtualization method to function, it must be compatible with the same operating system as its host. It is widely used to improve today’s complex software environment’s security, manageability, and availability, with small runtime and resource overhead.
Example: Docker
Key Benefits Server Virtualization Can Bring Your Business
Here’s a list of advantages businesses can get after leveraging the right Server Virtualization OS.

Server Virtualization: 5 Drawbacks and Solutions
Because server virtualization offers so many advantages, possibly one might overlook some of its drawbacks that businesses are forced to address at some point.
1) Running High-Demand Applications: Virtualization isn’t suitable for servers running high-demand applications because it splits the server’s processing power among multiple virtual machines. This division can lead to significant slowdowns when the server’s CPU can’t handle the load, causing tasks to take much longer and potentially leading to system crashes.
Solution: Network administrators should carefully evaluate CPU usage before implementing virtualization on such servers.
2)Backups: Creating backups can be challenging due to frequent software changes.
Solution: Using tools like Windows Server Backup can make the process more efficient, centralized, and convenient.
3)Licensing Compliance: If you exceed the number of licensed VMs allowed for the program, using licensed software in a virtual environment could lead to compliance issues.
Solution: Please ensure compliance with licensing when building virtual machines (VMs) and also monitor the usage of licensed software as the virtual environment expands to ensure compliance.
4)Software Compatibility: Not all software is designed for virtual environments, which can limit the number of compatible servers and applications. Although improving, software licensing is still challenging.
Solution: Conduct extensive compatibility testing before deploying new software in a virtualized environment.
5)Scalability Issues: Virtualization can complicate scaling operations. As virtualized networks grow, they may slow down because multiple network components share the same resources. This can be problematic for organizations looking to expand and utilize these shared resources effectively.
Solution: Evenly distributing workloads across virtual machines and physical servers, load balancers will ensure efficient resource utilization by preventing any single server become an obstacle.
