It is a program that allows multiple operating systems to share a single hardware resource host. Each operating system appears to have the host’s processor, memory, and other resources on it. However, the hypervisor is actually controlling the host processor and resources, allocated to each operating system is called guest operating systems (called virtual machines).

Types of hypervisor :-Bare Metal and Nested Metal
VMware ESX and ESXi are both bare metal hypervisor architectures that install directly on the server hardware.
vSphere ESX architecture relied on a Linux operating system, called the Console OS (COS) or service console to perform management functions, scripts and installing third-party agents for hardware monitoring, backup or systems management.
In the vSphere ESXi architecture, the service console has been removed. The smaller base code on vSphere ESXi represents a small size OS and improving reliability and security.
ESX vs ESXi
ESXi has no service console which is a modified version of RHEL.
ESXi is extremely Thin, hence results in fast installation + fast booting.
ESXi can be purchased as an embedded hypervisor in hardware
ESXi has built-in server health check status

2. About VMware VMware was founded in 1998 and the company headquartered is in Palo Alto, California. It has over 500,000+ customers globally. CEO is Patrick P. Gelsinger VMware creates server and desktop virtualization software that streamlines IT operations across the general IT infrastructure in Data centers , throughout the cloud and on mobile devices. VMware Data center platform are Vmware vSphere , which is also part of its VMware vCloud

4. Types of virtualization Type 1 Hypervisor :- Bare Metal vSphere ESXi 6.7 VM OS App VM OS App VM OS App VM OS App VM OS App VM OS App Host Hypervisor Virtual Machines Virtual Appliances HDD CPU RAM NIC vSphere ESXi is Linux kernel based OS vSphere ESXi directly installed on hardware. High performance It is completely independent from any Operating System. Hypervisor share and manage the hardware resources between different VM. A major advantage is if any problems in VM or OS do not affect the other VM or OS. Examples: VMware ESXi Server, Microsoft Hyper-V, Citrix/Xen Server

7. What is Vmkernel ? The VMkernel that is the foundation of the virtualization process. It’s the VMkernel that manages the virtual machines access to the underlying physical hardware by providing CPU scheduling, memory management, and virtual switch for data processing.
