As a bare metal hypervisor, ESXi runs directly on the host machine’s hardware, allowing it to optimize resources and provide efficient virtualization.

ESXi offers a range of powerful features that enhance enterprise virtualization. One of its standout capabilities is high availability, which ensures uninterrupted availability of virtual machines by automatically restarting them on another host in the event of a host failure. Additionally, ESXi enables clustering, enabling seamless management of multiple hosts through the vCenter Server. This facilitates convenient administration, resource allocation, and load balancing of VMs.

ESXi is a leading choice for enterprise virtualization due to its advanced features, scalability, and compatibility with various applications and workloads. It provides a secure and efficient virtualization platform that meets the demands of large-scale organizations.

Key Features of ESXi:

• High availability for uninterrupted VM availability
• Clustering for centralized management and resource allocation
• Support for live migration of virtual machines
• Robust security options to protect VMs
• Compatibility with various applications and workloads

ESXi offers a free version that allows users to experience its capabilities, although it has certain limitations. However, even with these restrictions, the free version still enables the creation and operation of a limited number of virtual machines without any CPU or memory restrictions, making it a viable option for smaller-scale deployments or for users wanting to explore and familiarize themselves with ESXi.
