Presented at ServerlessConf NYC 2016. There are a number of open source projects built around closed platforms like AWS Lambda/Google Cloud Functions and open serverless projects like OpenWhisk and LeverOS. In this talk we'll cover what motivates contributors, what sends them running the other direction, and how you can help your project grow. Building a project on top of closed technology is an extra challenge without insight into where it's going. Learn how to manage continuous integration with your project against your (closed) dependencies and make sure bugs stay fixed.
