Amazon's Cloud Exodus?

itwbennett writes: There are rumblings around this week's OpenStack conference that companies are moving away from AWS, ready to ditch their training wheels and build their own private clouds. Inbound marketing services company HubSpot is the latest to announce that it's shifting workloads off AWS, citing problems with 'zombie servers,' unused servers that the company was paying for. Others that are leaving point to 'business issues,' like tightening the reins on developers who turned to the cloud without permission.
