VMware

VMware is a leading software company providing virtualization and cloud computing solutions, enabling businesses to run multiple virtual machines (VMs) with different operating systems on a single physical server, maximizing hardware use, improving efficiency, and creating flexible, software-defined data centers with integrated compute, storage, and networking. Its core technology, the hypervisor (like ESXi), creates an abstraction layer, allowing independent VMs to share resources while maintaining isolation for applications, from desktops (Workstation, Fusion) to enterprise-level private clouds.
