I have had a meeting with "CTO" of pretty big factory. I was suppose to propose a new cloud solution for existing Sharepoint application. Unfortunately we didn't get into any agreement , because the dude only accepts SharePoint solutions and when I started talking about the cloud, he literally went nuts. He later have told me that he has been working here for over 20 years. The technical staff of that factory is just him and some other young guy and they only task they doing is to maintain complex Sharepoint infrastructure. If we hosted application in the cloud, he would lost his job.
