I don't get this. Didn't Kubernetes come out of Google Borg that had been in use forever? The second write should be more elegant and impressive -- why so many basic bugs?
Also, any large scale system like Borg developed at a large company like Facebook or Google will have completely opinionated one-way-of-doing-things for a lot of aspects. This doesn’t work for the world outside where lots of developers from different backgrounds, lots of projects with different requirements exist.
> The Borgmaster is a monolithic component that knows the semantics of every API operation. It contains the cluster management logic such as the state machines for jobs, tasks, and machines; and it runs the Paxos-based replicated storage system used to record the master’s state.
So it sounds as though Borg includes its own storage system. As I understand, Google has a set of (very complex) libraries written in C++ that implement Paxos/Multi-Paxos[2], which they have not open sourced.

The implementation is effectively entirely from scratch, so bugs will exist.
