Historically, centralization in the computer world grew from the glass house in which the one computer a company or institution could afford to buy or lease was installed -- and programmed by the tech gurus colocated there. The centralization and batch processing constraints of that era are now obsolete, having been replaced by inexpensive distributable computing, data storage and network building blocks. I suspect that many organizations haven't fully embraced the far more reliable, dependable and scalable approach to delivering services is related more to managerial issues ("tried and proven") than technical creativity and ability. The "C-Team" needs to be sold on the benefits that are obvious to the tech gurus of today, in language corporate leadership can understand and motivate their commitment.
