The current enterprise infrastructure is expensive, designed and based on the need to preserve the status quo rather than deliver optimal services. Thinking in terms of services we must deliver, the platform becomes less and less relevant. Look at the percentage of services we can get from the Cloud (both external and internal), the platform becomes nearly irrelevant.

We have to “buy” the most cost-effective platform. Microsoft Windows is not cost effective — it requires its own set of services just to provide a minimal platform. No, it will not all go away with Linux, but many of them do, or become a much smaller problem and require a lot less engineering & architecture to provide required services.
Change happens in volatile times.  This is a volatile time…
