Note: Material furnished herein are copyright protected. © 2015: Dhiman Deb Chowdhury. All Rights Reserved. In previous article, I have discussed about historical perspective of system virtualization ( http://dhimanchowdhury.blogspot.com/2015/07/network-virtualization-101-prelude.html ): how the need to integrate IBM’s disparate systems to share resource and enable multitasking led to the development of system level virtualization.

Today’s SEC investigation against Goldman Sachs ( http://www.forbes.com/2010/04/16/goldman-sachs-paulson-markets-equities-sec.html?boxes=financechannelforbes ) emboldens my contention about corporate sustainability.
