Server Virtualization Software is one of the most critical software you currently need. We know!
Virtualization has become a fundamental technology in modern IT. The global desktop virtualization market is expected to reach $26.2 billion by 2030.
Virtualization, an innovative computer science and networking solution, aims to lower costs and boost efficiency. It involves creating a layer between computer hardware and software systems and optimizing resource allocation to enhance performance.
What is Virtualization Software?
Virtualization software creates a digital version of an item like a server, storage device, or network resource. The digital version functions in its separate environment, apart from the physical hardware on which it runs. This software helps companies simplify their hardware resources, become more flexible, and scale better.
The significant advantage of virtualization software is running multiple virtual machines on a single physical server. Businesses can use this feature to optimize their hardware resources, shrink the quantity of required physical servers, and cut down maintenance and energy expenses. Virtualization software also performs simple migration of virtual machines across different physical servers, boosting reliability and improving disaster recovery.
Virtualization software can also safely trial and build new applications in a distinct environment. This feature lets businesses innovate and test without disturbing their active systems. Virtualization software simplifies creating backup copies of virtual machines to safeguard crucial data, which can be quickly restored if a system fails.
What is Meant by Server Virtualization Software?
Server virtualization software is commonly used in today’s data centers. Virtualization means creating a whole computer in a virtual way instead of physically.
Server virtualization splits one physical server into several virtual servers using virtualization software.
Each virtual server can have its operating system and work independently. Plus, one device can run multiple virtual machines (VMs) at once.
Why is Server Virtualization Needed?
Server virtualization is essential because it reduces the number of physical servers required, simplifies server management, lowers server housing and maintenance costs, and significantly minimizes wasted resources.
1. Reduce Costs
Server virtualization reduces costs by enhancing the utilization of existing resources, reducing the necessity for physical servers, lowering management costs, decreasing energy consumption, and cutting cooling requirements.
2. Quicker Server Provisioning and Deployment
Most new applications require a new physical server. The traditional approach involves purchasing and installing a new server for each application, often taking weeks.
In contrast, setting up and deploying Virtual Servers is a fast and easy process that doesn’t require any new server or installation.
3. Enhanced Disaster Recovery
The deployment of server virtualization facilitates the implementation of an effective disaster recovery plan, as data or applications can be moved quickly from one server to another.
A single server can host a lot of Virtual Machines. Therefore, the creation of a replication site can be simple and effective.
Most virtualization software also allows you to test disaster recovery failovers, which is an almost impossible protocol with many physical servers.
Before moving to the best virtualization software, let’s start exploring the different types of server virtualization software.
Different Types of Server Virtualization Software
Hypervisor-Based Virtualization
Hypervisor-based virtualization is a crucial form of server virtualization that lets several virtual machines run on a single physical server. It relies on a hypervisor, which falls into two categories:
- Type 1 (Bare-Metal Hypervisors): These hypervisors run directly on the physical hardware without needing a host operating system. They offer better performance and resource efficiency.
- Type 2 (Hosted Hypervisors): These run on top of an existing operating system and are generally easier to set up but less efficient than Type 1 hypervisors. Examples include:
Examples: VMware ESXi, Microsoft Hyper-V, XenServer
Examples: VMware Workstation, Oracle VM VirtualBox
Container-Based Virtualization
Container-based virtualization, also known as containerization. This virtualization packages applications and their dependencies into containers. These containers can run on any system that has the necessary container runtime. Containers are lightweight and offer excellent performance, making them ideal for microservice architectures and DevOps practices.
Examples: Docker, Kubernetes
Full Virtualization
In full virtualization, hypervisors duplicate the entire hardware setup, allowing guest operating systems to run without any changes, similar to real hardware. This method guarantees strong compatibility and isolation between virtual machines.
Examples: VMware vSphere, Microsoft Hyper-V
Paravirtualization
Paravirtualization enhances performance by changing the guest OS, reducing virtualization overhead. It provides better performance than full virtualization but needs compatible guest OS adjustments.
Examples: Xe, KVM(Kernel-based Virtual Machine)
Operating System-Level Virtualization
Containerization, also called operating system-level virtualization, virtualizes the OS instead of the hardware. It enables multiple separate user-space instances, called containers, to operate on one OS kernel.
Examples: LXC(Linux Containers), OpenVZ
Hybrid Virtualization
Hybrid virtualization combines complete and paravirtualization features to offer advantages to both techniques. It enhances performance and compatibility by switching dynamically between full and paravirtualized modes as necessary.
Examples: VMware’s Virtual Mchine Monitor(VMM), Oracle VM

Selection Criteria We Set to Select the Best Server Virtualization Software
When selecting the best server virtualization software for your business, it’s crucial to consider various factors to ensure an informed decision.
1. Performance and Resource Management
Efficient resource utilization and optimal performance are crucial for virtual machines. The VPS software enables IT professionals to allocate and manage CPU, memory, and storage for each VM according to its requirements.
Advanced features like dynamic resource scheduling and load balancing ensure optimal resource distribution among VMs, preventing any single VM from taking up all the resources.
Performance monitoring tools offer real-time insights into resource usage and performance metrics.
2. Scalability
Scalability is another crucial factor to consider. Some virtualization software can scale more effectively, accommodating many virtual machines (VMs).
Opting for a platform capable of scaling VMs up and down based on demand can offer significant benefits.
3. Security and Isolation
VMs operate in isolated environments, keeping processes, data, and system configurations separate; this prevents issues in one VM from affecting others, ensuring security.
VM software includes features like firewalls and isolated networks for enhanced security control.
4. Compatibility and System Prerequisites
Compatibility with different hardware architectures is crucial for virtual machine software or VPS software.
While most support x86_64 architectures, compatibility with ARM-based systems is increasingly important due to the rise of energy-efficient ARM servers; this expands the software’s applicability in various environments, from data centers to edge computing scenarios.
5. Usability and Administration
Leading VM software usually boasts a user-friendly interface for effortless VM creation, configuration, and management. It encompasses graphical user interfaces (GUIs) and command-line tools and caters to diverse user preferences and expertise levels.
Another important usability aspect is the ease of moving virtual machines (VMs) between hosts or from physical to virtual environments.
This capability ensures flexibility and reduces downtime during hardware upgrades, maintenance, or disaster recovery.
