In his CA keynote, Dr. Ajei S. Gopal, EVP of the Products and Technology Group, introduced the best simple way of understanding the ongoing transition to "Cloud" computing that I've heard so far. He said that IT is going through a transition very much like what manufacturing has gone through for many companies over the last decade. For example, today Cisco manufactures essentially nothing, instead using a network of contract manufacturers and logistics specialists. Ajei's point was that if you're part (say) of Cisco's Global Supply Chain Management team ("manufacturing") your mission is getting high-quality products quickly to Cisco's customers at the lowest possible cost (where "high-quality" and "quickly" are complex issues). If a company does its own manufacturing there is the risk of focusing on (say) the fact that you are best-of breed at wave soldering 21-layer PC boards, and thinking that's what counts the most, whereas the supply chain mission is pure and aligned with the business. Legacy IT shops are very much like legacy manufacturing. Moving forward, more and more options open up for outsourcing aspects or all of IT (e.g., use of SP resources, SaaS, ...). The new (and better aligned) IT mission is a direct analogy: how can you deliver high-quality, agile services and applications to the business at the lowest possible cost?
