Difference between ESX and ESXi

Hello,

What is exactly the difference between ESX and ESXi work station. Also what is the concept of Hypervisor in this. How many kind of virtualisation can be configured.

Re: Difference between ESX and ESXi

Hello,

ESXi is the VMware ESX, but only the hypervisor kernel itself with no service console. Licenses, administration with VI client or vCenter is the same.

Re: Difference between ESX and ESXi

Hello,

VMware ESX and VMware ESXi are both bare-metal hypervisors that install directly on the server hardware.
Both provide industry-leading performance and scalability; the difference resides in the architecture and
the operational management of VMware ESXi.
Although neither hypervisor relies on an OS for resource management, VMware ESX relies on a Linux operating system, called the service console,
to perform two management functions: executing scripts and installing third party agents for hardware monitoring, backup or systems management.
The service console has been removed from ESXi, drastically reducing the hypervisor footprint and completing
the ongoing trend of migrating management functionality from the local command line interface to remote management tools.
The smaller code base of ESXi represents a smaller â attack surfaceâ and less code to patch, improving reliability and security.
The functionally of the service console is replaced by remote command line interfaces and adherence to system management standards.

Re: Difference between ESX and ESXi

vmware announces ESXi as the future for virtualization

ESXi:
- is more secure -has not service console
- less code to patch
- less code to patch means more secure since you - well vmware - has more control on they deploy
- faster implementation in fact you can buy a HP server with a usb ESXi on it
- and more here
