The most challenging part was the domain and how to break down the domain into these discrete units. The risk of getting it wrong was very high. So imagine that you were rooting part of the traffic through that just to see how it would behave at a small scale. And one of the things that we've worked on recently is we want to get a better idea of the productivity of our warehouses. Every single movement happens in the warehouse gets replayed to Kafka through something called CDC. Once it's in Kafka, as many applications as you want can consume those movements and then reason with them however they want for different data set. That's what we currently feeding off to our third party provider.

Episode notes
Alex Sims, a Senior Software Engineer at James & James, an eCommerce fulfilment company, reached out to us about the Kaizen story of the third-party logistics (3PL) platform that he has been involved with for several years now.
The system delivered 16 millions of orders in 10 years, and 4.5 million in the last year alone. All the numbers are going up, and there is only so much that a single PHP monolith deployed as VM images can handle. So how do you even start thinking about the architectural improvements, and inspire everyone involved to move towards better?
We encourage you to look at the architectural diagrams in the show notes, especially the 10 year roadmap, and ask Alex for a blog post follow-up. While today’s episode was a good conversation starter, there is a lot that we did not have time to cover.
