In today’s ever-changing computing landscape, virtualization technology has revolutionized hardware resource utilization. At the core of this groundbreaking technology are virtual machines (VM) tools that create and manage multiple isolated computing environments within a single physical host. Virtual machines come in various forms, such as virtual desktop infrastructures or fully functional servers. These virtualized applications, servers, and machines provide scalable and versatile functionality for users. With virtual machines, you can experiment with new operating systems, create virtual disk images, or even construct an entire database server in the cloud. The best part is that many server virtualization tools are free or open source, saving you money when building your computer. So, what are the best free virtual machines for 2023? Here are the top tools ranked alphabetically: Azure Virtual Machines, Citrix Hypervisor, KVM, Oracle VM, Proxmox VE, QEMU, VirtualBox, VMware ESXi, VMware Fusion, and VMware vSphere. These tools offer various features and capabilities for users looking to harness the power of virtualization. Whether you need infrastructure as a service (IaaS) providers, virtual desktop infrastructure (VDI) software, or remote access solutions, there is a virtual machine software to suit your needs.
