Virtual machines still have a place in modern infrastructure, but containers are an essential technology. In the past, virtualization was very popular. It served as the main method for executing services in a “sandbox” setting for a while. Hundreds of virtual machines were used by IT departments. Then came containers, which used a fraction of the resources needed to accomplish much of what a virtual machine could. Virtual machines appeared clumsy, but container technology did not completely replace them. In actuality, there are five reasons why virtualization is still beneficial today.

Distro Hopping
Distro hopping is the practice of frequently switching between different Linux distributions in search of the perfect fit for one’s needs. Many Linux enthusiasts enjoy exploring various distros to experience different desktop environments, package managers, and system architectures. Some do it out of curiosity, wanting to experiment with new features, while others seek better performance, stability, or compatibility with their hardware. The open-source nature of Linux allows for a vast number of distributions, each with unique strengths, making it tempting for users to keep exploring.
For some, distro hopping is a way to find a system that best supports their workflow, whether for software development, cybersecurity, multimedia production, or general use. Some users prefer rolling-release distributions like Arch Linux for cutting-edge updates, while others stick to fixed-release options like Ubuntu for stability. Security-focused users may explore distros like Qubes OS or Tails, while those seeking a lightweight system might try Alpine Linux or Puppy Linux.
Despite the excitement of trying new distros, constant hopping can also be time-consuming, requiring frequent system setups and configurations. Eventually, many users settle on a distribution that balances their preferences for stability, performance, and usability. However, for those who enjoy testing and experimenting, distro hopping remains an engaging journey through the diverse Linux ecosystem.
Testing and Development
Another major advantage of VMs is their flexibility in testing and development. Developers use VMs to test applications across multiple operating systems without needing dedicated hardware. This is particularly useful for software compatibility testing, ensuring applications run smoothly on different platforms. VMs also allow users to experiment with different operating systems, making them valuable for education, research, and training.
Developers can test programs in a controlled environment without compromising the host system by using virtual machines (VMs) to build isolated environments that replicate various operating systems, settings, or network arrangements. This lowers the possibility of compatibility problems, speeds up the development process, and enhances software quality.
Support and documentation
Bug reports can be extremely detailed, and occasionally a quick glance at GDB will reveal the root of an issue. On other occasions, though, a bug report is received that concerns the process rather than the code. For example, a user may express dissatisfaction with an application’s layout, how it interacts with a desktop widget, or how to complete a complicated setting. In situations like those, you may need to attempt to duplicate the user’s workflow, which occasionally necessitates running the user’s actions exactly as they are.
Server Virtualization
In enterprise environments, VMs are widely used for server virtualization, improving resource utilization and scalability. Organizations can run multiple virtual servers on a single physical machine, reducing hardware costs and power consumption. Additionally, VMs provide robust backup and disaster recovery solutions. Snapshot and cloning features allow quick system recovery in case of failures, minimizing downtime and data loss.
Enhanced Security and Isolation
Another key reason VMs remain important is their role in enhancing security and isolation. Each virtual machine operates independently, with its own dedicated resources and isolated environment. This isolation ensures that if one VM is compromised, the others remain unaffected, providing a robust layer of protection for sensitive data and applications. This makes VMs an ideal choice for testing new software, running legacy applications, or hosting critical systems that require a high degree of security.
Virtual Machines for Cloud Computing
Lastly, virtual machines (VMs) are a key component of cloud computing. Virtualisation is used by several cloud providers to give their clients scalable, on-demand resources. In order to meet the increasing demand for cloud-based services, virtualised data centers—where resources may be dynamically allocated and managed—can be created thanks to virtual machines (VMs).
In summary, virtual machines continue to be an essential technology because of their adaptability, security, capacity for disaster recovery, usefulness in software development, and contribution to cloud computing. Virtual machines (VMs) will probably change and continue to be an essential part of IT infrastructure for years to come as technology advances.
