Tale 1: Carving out a Java Microservice from a Ruby Monolith

A Ruby Monolith was causing large AWS bills, so the organization decided to do something about this. It turns out that there are obstacles when carving out Java microservices from a Ruby monolith, and not all of them are technical.

Tale 2: Migrating 190M records from DynamoDB and S3 to MongoDB

In one of our projects, we had to migrate 190M records from DynamoDB and S3 to MongoDB. In a live system.

This is the story of how we achieved that: how we did that, what went wrong along the way, and what we did about those things. This is about both, the migration script as well as the service reprogramming.
