Hypervisor: A server without OS

A machine or web server without an operating system? Are we going back to our olden days of computer. Look at the new weblogic server virtual edition from BEA. It runs only on an x86 hypervisor and does not support none of the operating system.



A hypervisor is a thin layer of low level code that sits just above the hardware and creates a virtualized version of that hardware. Normally, we have our operating system windows or linux running on a hardware and virtual machines like java runs on top of the OS executing the bytecode and web applications runs above Java.

BEA has removed the operating system layer and currently it supports only x86 hypervisor and in future, they are in plan to support XEN and MS Virdian.

Linux has the largest share in the server market and microsoft stands far next. Is this going to take Linux market share? Lets' watch.

BEA is not the first company in introducing the idea. IBM uses same concept for thier mainframes. But BEA is the first to introduce in Intel and AMD chipset.
