VMware ESXi
VMware ESXi is a bare-metal hypervisor that enables server virtualization by allowing multiple virtual machines (VMs) to run on a single physical server. It provides a lightweight, secure, and efficient virtualization layer that abstracts CPU, memory, storage, and networking resources, managed through tools like vSphere Client or vCenter Server. It is widely used in enterprise data centers for consolidating servers, improving resource utilization, and supporting cloud infrastructure.
Developers should learn VMware ESXi when working in environments that require server virtualization for tasks such as deploying and managing multiple VMs, testing applications across different operating systems, or building private clouds. It is essential for roles in IT infrastructure, DevOps, or cloud engineering, as it supports high availability, disaster recovery, and scalable resource management in enterprise settings.
