VMware ESXi
VMware ESXi is a type-1 hypervisor introduced by VMware in 2008 as part of its vSphere virtualization platform. It is a lightweight, bare-metal hypervisor that allows multiple virtual machines (VMs) to run on a single physical server by abstracting the underlying hardware resources. Unlike traditional operating systems, VMware ESXi operates directly on the server hardware, providing better virtualization performance, reduced virtualization overhead, and enhanced virtualization reliability. Its minimalistic virtualization architecture is designed for enterprise virtualization environments that require efficient virtualization resource utilization and robust virtualization capabilities.

One of the distinguishing features of VMware ESXi is its small footprint, which enhances virtualization security by reducing the attack surface. The hypervisor includes advanced features like memory overcommitment, storage virtualization, and virtualization live migration using vMotion. It also integrates with enterprise tools such as vCenter Server, enabling centralized virtualization management, virtualization monitoring, and virtualization automation of virtualized environments. These features make VMware ESXi a key component in modern data center virtualization and cloud computing virtualization infrastructures.

VMware ESXi supports a wide range of enterprise applications, including those requiring virtualization high availability, virtualization disaster recovery, and virtualization scalability. It is compatible with major virtualization technologies like VT-d and AMD-V, enabling secure virtualization and efficient direct device assignment to virtual machines. VMware ESXi has become a critical solution for organizations seeking to optimize their IT operations, reduce costs, and increase agility in deploying workloads.
