What type of hypervisor is ESXi classified as?

ESXi is classified as a Type 1 hypervisor, also known as a bare-metal hypervisor. This classification is based on the architecture and operational characteristics of the hypervisor. A Type 1 hypervisor runs directly on the host's hardware without the need for a host operating system, which leads to optimal performance and resource utilization. This setup allows for better efficiency, as the hypervisor has direct access to the physical resources of the server.

In the context of virtualization, ESXi creates and manages virtual machines (VMs) by abstracting the hardware resources for them to operate. It efficiently allocates CPU, memory, storage, and networking resources directly to the VMs. This direct interaction with the hardware enables features like better performance, enhanced security, and reduced overhead compared to hypervisors that require a host OS.

While other types of hypervisors exist, such as Type 2 hypervisors, which run atop a conventional operating system, they do not provide the same level of integration with the hardware as Type 1 hypervisors. The other options, such as hybrid or cloud hypervisors, refer to different architectures or deployment models that do not apply to ESXi. Therefore, the classification of ESXi as a Type
