John, I am not sure I would agree with ZDNet - in fact one of my posts from a few months ago actually argues the opposite!
Whilst cloud based services may be increasingly easy to procure, we still have a long way to go before an end user in any business function can bolt together numerous services to make a complete IT ecosystem.
I would go further and suggest that now more than ever a company needs a top class IT Organisation in order to ensure the interconnectivity and appropriate security that a business needs.
