No Cloud without Virtualization

SUN, IBM, HP tried before (Utility computing, On-demand computing etc)But nobody could get right usage model which makes sense for commercial worldcommercial worldThe form factor, usage model, total control to end user are key reasons of success for cloud computing todayThis would not have been possible without virtualizationThis would not have been possible without virtualizationHow & Why Amazon built Cloud

Invested billion plus $$ in infrastructureHuge excess idle capacityLeveraged open source Xen to create a glueThat translates physical infrastructure to unified logical

infrastructureThis allowed them to create the right form factor, usage model &

flexibility to end user

Complex SAP Landscape

The LayersBy Stanley Kunitz

I have walked through many lives, some of them my own, and I am not who I was, though some principle of being abides, from which I struggle not to stray. When I look behind, as I am compelled to look pbefore I can gather strength to proceed on my journey, I see the milestones dwindling toward the horizon and the slow fires trailing from the abandoned camp-sites, over which scavenger angels wheel on heavy wings wheel on heavy wings. Oh, I have made myself a tribe out of my true affections, and my tribe is scattered! How shall the heart be reconciled to its feast of losses? In a rising wind the manic dust of my friends, those who fell along the way, bitterly stings my face. yet I turn, I turn, exulting somewhat, with my will intact to go wherever I need to go, and every stone on the road precious to me precious to me. In my darkest night, when the moon was covered and I roamed through wreckage, a nimbus-clouded voice directed me: "Live in the layers, not on the litter." Though I lack the art to decipher it, no doubt the next chapter in my book of transformations is already written, I am not done with my changes.
