What an awful article. While it makes some decent points provided you mentally substitute terminology, it's entirely based on a false dichotomy and a conflation of concepts, such that 'open source' means software you obtain and then host on your own premises, while 'lambda' is stuff that's offered as utility computing with economies of scale and their pieces will magically integrate with your custom business logic. It's not entirely garbage, as it's true that cloud computing is a threat to on-premises computing; and that reliance on cloud computing typically means their offerings are closed source black-boxes that behave according to their APIs, which you have to code against. But there could've been a less sensational, and more disciplined way to make that (oft-rehashed) point.
