I'm the author of that post. Thank you for your feedback.

The production code is proprietary work for clients, so I can't link to it directly. But the tooling I built to support the pipeline is open source: the log analyzer that computed these statistics.

There are a couple of other in-flight projects I will open source soon, created by this process, but they aren't out yet.

The research page is about the methodology because that's what generalizes. The specific microservices I ship are just microservices.
