CIOs Need To Realize That Virtualization Isn't All That It's Cracked Up To Be (a chief information officer needs an IT strategy to create IT alignment)

The Accidental Successful CIO

Sure Virtualization Seems Neat In The Beginning, But…. To read the IT trade journals or speak with CIOs you’d think that we’ve all found the magic silver bullet that IT’s been looking for during the past few years: server virtualization. What Is Virtualization?

” The speakers are Recep Ozdag, a PME with Intel, and Gershon Schatzberg, a PLM with Wind River Systems. The first concept that Recep discusses is network virtualization. He believes that network virtualization is primarily about decoupling network services from the underlying network infrastructure. The virtual network must provide the same services as the physical network, but can provide greater flexibility, automation and programmability, and isolation.
