What is ESX architecture?
The VMware ESXi architecture comprises the underlying operat- ing system, called VMkernel, and processes that run on top of it. VMkernel provides means for running all processes on the system, including management applications and agents as well as virtual machines.
What is the difference between the vSphere ESX and ESXi architecture?
The last VMware release to include both ESX and ESXi hypervisor architectures is vSphere 4.1 (“vSphere”). The primary difference between ESX and ESXi is that ESX is based on a Linux-based console OS, while ESXi offers a menu for server configuration and operates independently from any general-purpose OS.
Is ESXi a Type-1 hypervisor?
VMware ESXi (formerly ESX) is an enterprise-class, type-1 hypervisor developed by VMware 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.
What is vCenter architecture?
The vCenter Server architecture consists of three main components: vSphere Web Client, vCenter Server Database and vCenter Single Sign-On. The vSphere Web Client is a web application that acts as the vCenter Server user interface.
What OS does VMware ESXi run on?
VMkernel operating system
VMware ESXi is an operating system-independent hypervisor based on the VMkernel operating system that interfaces with agents that run on top of it. ESXi stands for Elastic Sky X Integrated. ESXi is a type-1 hypervisor, meaning it runs directly on system hardware without the need for an operating system (OS).
What is Type 1 virtualization?
Sometimes called a “bare metal hypervisor” or “native” because it runs directly on a bare metal physical server, a type 1 hypervisor has direct access to the hardware. With a type 1 hypervisor, there is no operating system to load as the hypervisor that you load IS the operating system.
What is the difference between Type 1 and Type 2 virtualization?
The main difference between Type 1 and Type 2 Hypervisor is that Type 1 Hypervisor runs directly on the host’s hardware while Type 2 Hypervisor runs on an operating system similar to other computer programs. Moreover, a hypervisor is related to virtualization. It is a Virtual Machine Monitor (VMM).
What does VC stand for in VMware?

Which is part of the VMware ESXi architecture?
On ESXi hosts, the management component is based on a limited implementation of the POSIX environment and interface and an integrated set of busybox tools. The VMware ESXi architecture comprises the underlying operating system, called VMkernel, and processes that run on top of it.
Is the Service Console in VMware ESXi deprecated?
Both of these Console Operating System functions are being deprecated from version 5.0, as VMware migrates exclusively to the ESXi model. The Service Console, for all intents and purposes, is the operating system used to interact with VMware ESX and the virtual machines that run on the server.
How big is the image of ESXi 5.0?
ESXi is designed for distribution in various formats, including directly embedded in the firmware of a server or as software to be installed on a server’s boot disk. The size of the ESXi (5.0) image is 144 MB on disk. This size may increase with future updates, fixes, drivers and functionality.
