Hi Gris and everyone, Not a very techie post, but thought I'd contribute a little on the economic case for open-source, and Apache Beam in particular.
TLDR; We're finding that, at critical points in our sales cycle, our customers are choosing us precisely because we offer a 'call option' on future runner choice. http://blog.atso.com/how-open-source-is-reshaping-our-business I thought it would be refreshing to hear this, since lots is written on technical/community benefits of open source and how (obviously) it helps you save costs on otherwise-proprietary/expensive solutions. Little's been written about positive impact on revenue-side of the ledger. Best, Peter CTO ATS, Inc.
