I recently spoke with Alex Benik of Battery Ventures, who argued the IT market has come to expect the ease-of-use and agility of public cloud services like AWS (Amazon Web Services).
Alex stated that internal IT organisations are increasingly benchmarked against AWS by their internal customers in terms of ease-of-use and speed. For traditional enterprises, that do not have the scale and resources of Amazon, it is very hard to meet the AWS service levels.
As circumstances would have it, soon after I picked up these insights I spoke with Platform9. They offer internal IT organisations a way to build a private cloud that approaches the agility and ease-of-use of AWS.
