Does anyone even try to sell closed-source software anymore? It must be hard, when so many of the tools used to power the world’s largest datacenters and build the likes of Google, Facebook, and LinkedIn have been planted on GitHub for everyone to use. Even Google’s magic sauce, the software that knows what you will read or buy before you read or buy it, is now freely available to any ambitious developer with dreams of a smarter application.

Google didn’t used to share its source code with the rest of us. It used to share research papers, then leave it to others to come up with the code. Perhaps Google regrets letting Yahoo steal its thunder with Hadoop. Whatever the reason, Google is clearly in the thick of open source now, having launched its own projects — TensorFlow and Kubernetes — that are taking the world by storm.

Of course, TensorFlow is the machine learning magic sauce noted above, and Kubernetes the orchestration tool that is fast becoming the leading choice for managing containerized applications. You can read all about TensorFlow and Kubernetes, along with dozens of other excellent open source projects, in this year’s Best of Open Source Awards, aka the Bossies. In all, our 2016 Bossies cover 72 winners in five categories:

The software tumbling out of Google and other cloudy skies marks a huge shift in the open source landscape and an even bigger shift in the nature of the tools that businesses use to build and run their applications. Just as Hadoop reinvented data analytics by distributing the work across a cluster of machines, projects such as Docker and Kubernetes (and Mesos and Consul and Habitat and CoreOS) are reinventing the application “stack” and bringing the power and efficiencies of distributed computing to the rest of the datacenter.
