Back in the day (5 years ago) I wrote a good blog post related to a migration the Engineering team did from a monolithic infrastructure into a "microservice based" architecture.

The original URL is this, but I've seen it has gone down a couple of times in the last days so I saved a copy of it in

The Path to Kueski 2.0 (Archive).

Another good blog post that is worth saving, is the Better Logging (Archive) post by Jorge del Rio which has good ideas about logging in production environments.
