vCenter Server Appliance (VCSA) is the centralized management utility for VMware, and is used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location. VMware vMotion and svMotion require the use of vCenter and ESXi hosts.
VMware vSphere (formerly VMware Infrastructure 4) is VMware's cloud computing virtualization platform. [ 2 ] It includes vCenter Configuration Manager, as well as vCenter Application Discovery Manager, and the ability of vMotion to move more than one virtual machine at a time from one host server to another.
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware, a subsidiary of Broadcom, for deploying and serving virtual computers.As a type-1 hypervisor, ESXi is not a software application that is installed on an operating system (OS); instead, it includes and integrates vital OS components, such as a kernel.
Hellwig's core claim is that ESXi is a derivative work of the GPLv2-licensed Linux kernel 2.4, and therefore VMware is not in compliance with GPLv2 because it does not publish the source code to ESXi. [130] VMware publicly stated that ESXi is not a derivative of the Linux kernel, [131] denying Hellwig's core claim. VMware said it offered a way ...
In VMFS3 and VMFS5 prior to vSphere 5.1, the maximum number of hosts which can share a read-only file is 8. This affects the scalability of linked clones sharing the same base image. In vSphere 5.1, this limit is increased to 32 with the introduction of a new locking mechanism.

VMware Workstation versions 12.0.0, 12.0.1, and 12.1.0 were released at intervals of about two months in 2015. [9] In January 2016 the entire development team behind VMware Workstation and Fusion was disbanded and all US developers were immediately fired.
A flat image allocates space ahead of time while a sparse image grows as the virtual machine writes to it. Flat images can use the underlying file system's sparse file capability, as is done with the vmfs format on ESXi. An image can also refer to a parent image and only store changes made in a copy-on-write fashion. This enables creating a ...
