It is frustrating that google is always 5 to 10 years ahead of everyone else but they never open source their back-end technologies (except recently with the ML stuff). The whole reason hadoop exists is because google only released whitepapers (which was good) but not code. I wonder whether google really benefits by this strategy, given that they have to be an ecosystem instead of benefitting from being a part of one. I also wonder whether the industry is better off by having to cooperatively reinvent the google architecture. I doubt the hadoop ecosystem would have arisen had it been google code at the heart.

Apache Beam, gRPC/protobuf, Kubernetes. There are examples besides Tensorflow.

Not code but they do publish papers that contain decent detail.
