In this article, we will introduce you to the concept of virtualization and its types. We will discuss some significant benefits, drawbacks, and use cases to present a holistic impact of virtualization for organizations.

Read along for an improved understanding of virtualization and its impact on the digital environment.


Virtualization is a process that separates a service of a computer system from its underlying physical resources. It enables the creation of virtual machines that are software-created versions of computing resources. The multiple virtual machines become independent computers running on their operating systems. Multiple operating systems and applications can run on the same computer hardware, increasing the flexibility and utilization of a physical machine.

The virtualization process is cost-effective, hardware-reducing, and energy-saving. The method effectively enhances the digital infrastructure's performance at low financial expenses, making it a common practice for organizations. Moreover, virtualization can be used in different environments like production and development environments.

It is also known as hardware virtualization that provides infrastructure as a service, forming the basis of cloud computing as it enables users to purchase the computing resources they need and scale them accordingly. Another important aspect of virtualization is providing a virtual environment for applications, storage, and networking.

Benefits of Virtualization

Virtual machines have redefined digital network accessibility for users and organizations. From eliminating computer hardware and storage devices to managing different operating systems, virtualization significantly changes an organization's digital environment. It offers an efficient and improved method for connectivity.

Benefits of virtualization

Let's look at some of the main advantages of virtualization.

Resource utilization

With the elimination of hardware resources in a virtualization setup, the initiation and expansion of virtualization have become more accessible. Resource utilization becomes faster and more straightforward as a completely virtual environment requires only one point of access to be used by an entire organization. It ensures maximum utilization of the computing power of available hardware resources. Hence, it allocates resources to a flexible and efficient process.


Virtualization is free of physical hardware. It only depends on physical computers and not even a single storage device for data processing. It also eliminates the need for large spaces to manage on-site resources. On the contrary, you must buy a license or access it from a third-party provider to become a part of a virtualized development environment. It leads to a significant cut down in expenses, making it a cheaper and more affordable solution for organizations. Moreover, relying on third-party providers for the virtualization process enables companies to predict costs and manage their financial resources accordingly.

Performance enhancement

Since third-party providers primarily manage virtual machines, they control the updates of hardware elements and the software layer. It reduces the workload of IT professionals within the organization, and they can focus on other aspects of network management. Moreover, virtualization enables companies to offer better uptime for user interaction. Hence, improving the overall performance of the organizations.

Hence, organizations can make the most out of virtualization with better resource provisioning and cutting down significant costs. A setup that ensures better performance of companies in the competitive digital space.

How does virtualization work?

Virtualization can be simply explained as creating a digital version of computer hardware. The virtualization process depends on the network and operating system details, but it follows some basic steps. Before we explain how it works, let's understand some basic terms associated with the process.

Virtualization creates a digital version of computer hardware (Wix.com)

  • Hypervisor - a software layer that provides an interface between the physical hardware and virtual machines
  • Host machines - an operating system that has the installed hypervisor
  • Guest operating systems - an operating system that runs in a virtual machine
  • Virtual machine - a virtual copy of the physical hardware, an application code that functions as a server

The process begins with creating virtual machines using a hypervisor-based on a single physical computing system. While all virtual machines connect to a single computer, each becomes an independent machine with its operating system. The hypervisor acts as management software that allocates resources to virtual machines as needed.

Types of Virtualization

Now that you understand virtualization and how it works, let's explore the various types of virtualization being implemented nowadays. The IT infrastructure can be virtualized at different levels in a network.

Types of virtualization

Following are some of the common types of virtualization

Application Virtualization

It enables remote access to applications software on a user's operating system without installing the app. Unlike desktop virtualization, it only runs the specific application in a virtual environment. While the physical server stores all the vital information of the application, the virtualization software makes it accessible on multiple operating systems through the internet. The three main application types are local application virtualization, application streaming, and server-based application virtualization.

Network Virtualization

Running on a standard physical network, it uses software to create multiple virtual networks with individual controls and data plans. It abstracts hardware elements into software running on a hypervisor. The two types of network virtualization are software-defined networking (SDN) and network function virtualization (NFV).

Desktop Virtualization

It allows users' operating systems to be stored remotely on a server, enabling multiple desktop operating systems to run on a single local computer using separate virtual machines. Virtual desktops allow users to access multiple operating systems on a single machine. The two significant types of desktop virtualization include virtual desktop infrastructure (VDI) and local desktop virtualization.

Storage Virtualization

It is an array of servers that are managed by a virtual storage system. Storage virtualization is a way to enhance the storage capacity of a network. All storage spaces become accessible as a single storage device for the entire network. It manages storage from multiple sources, ensuring smooth operations, consistent performance, and advanced functions. Storage virtualization provides more accessible storage for all virtual machines in a network.

Server Virtualization

It is one of the most common types of virtualization. It functions by masking the server resources. Server virtualization divides the central single physical server into multiple virtual servers. Since each virtual server has its unique identity and processor, it can operate its operating systems in isolation. It ensures better performance and reduced operational costs.

Data virtualization

Data is crucial for organizations in the modern-day digital world. It is collected from multiple applications in various formats from different locations through data virtualization. The data is logically arranged for virtual access. Data virtualization tools create a software layer between the applications and the systems. It translates the application's data request to provide results for multiple systems, breaking data distribution into different silos.

The different types of virtualization create better accessibility of platforms, data, servers, applications, or storage. It depends on the level of virtualization within the network.

Virtualization vs. Cloud Computing

While virtualization is the software that powers cloud technology, cloud computing is a digital service. They are two separate concepts in the digital world that work together in a hybrid cloud model where a virtual machine interacts with the cloud infrastructure for an improved online communication network. Combining the two enables organizations to maximize the benefits of cloud computing in a more secure and controlled environment due to virtualization.

Difference between virtualization and cloud computing (V2 Cloud)

Virtualization software can manipulate the hardware resources; cloud providers utilize that manipulation to provide a digital service to organizations and users. Cloud computing relies on the concept of virtualization to provide various services. Integrating these concepts creates a digital infrastructure that offers automated management, improved scalability, and significantly reduced financial expenses.

Server Virtualization vs. Containerization

Virtualization is a broader concept for digital infrastructures, while containerization is a type of virtualization. The former runs multiple operating systems on a single server, while the latter a single operating system with numerous user spaces. Virtualization enables users to share a digital space for data accessibility and storage, unlike containerization, which allows a single user to run processes simultaneously.

Virtualization isolates the operating system, while containerization isolates the host operating system machine. The former operates using a kernel-based virtual machine, and the latter creates containers for each user and its particular operating system. While virtual machines host a range of guest operating systems, containers are only specific to the host's operating system. Hence, virtualization is more inclusive as compared to the specificity of containerization.

Advantages of a Virtualized Development Environment

The virtualization hardware creates a development environment that offers several benefits to organizations. The maximum impact is on deployment times as the speed to set up the environment process is considerably reduced. It makes it easier to implement for new developers as well. The process can be completed in hours, making it a quick setup for companies.

Moreover, virtual machines enhance the flexibility of access for the users. Developers can work on multiple applications or projects on a single hardware. It enables users to easily contribute to different environments, making collaboration effective and hassle-free. The simplified process also ensures less time on maintenance activities, leaving more room for productive work and team coordination.

Lastly, the virtualized development environment is suitable for running tests on a cloned local environment without affecting the production environment. Since the environment is segmented into multiple virtual machines, developers can clone the desired virtual machine for testing processes while keeping the rest of the network unaffected.

Drawbacks of Virtualization

In a world of physical resources working in their physical environment, virtualization software expands your network's accessibility for users. However, like every technological advancement, it has its share of problems.

Drawbacks of virtualization

Let's look at some of the most common drawbacks of virtualization.

Security risks

While virtualization isolates a virtual machine from one's operating system, it still poses security risks. Viruses, malware, and ransomware attacks are the most common security threats when implementing virtualization technology. It can affect the entire virtual infrastructure, giving the hacker access to your virtual machine's control. It puts your data and the physical server at risk. Since data is a crucial part of today's technological world, security threats can devastate organizations. Hence, companies should be careful when implementing virtualization into their digital infrastructure.

Performance issues

Another major drawback of a virtual environment is a need for more control over your data-handling processes. Data accessibility relies on an organization's network management with the online virtualization infrastructure. Any breakdowns in the communication between the company and its data in the virtual environment can lead to availability issues for long periods. Hence, adversely affecting the performance of organizations in the highly competitive business world.

Management complexity

Network virtualization broadens the connections of your digital infrastructure. As a result, you are running multiple operating systems, virtual machines, physical components, and network resources together. It makes managing data services a complex process with reduced control of tasks as small as saving a file. Since several links have to work in synchronization, the process is complicated to manage. It demands greater efficiency and effective organization of data virtualization processes.

Hence, it becomes vital for organizations to navigate these issues when shifting from the limited space of a physical network to more liberating virtual environments.

Uses of Virtualization

Virtualization is rapidly developing as a foundational solution for organizations to improve their efficiency, performance, and storage. The idea is to revamp modern digital networks, and organizations increasingly opt for virtualization solutions.
