As part of a two-day microservices workshop I’m putting together, I’ve been thinking a lot about how to explain monolith-application decomposition and what a transition to microservices might look like. This is a small subset of that material, but I want to share it with you to get feedback (in the workshop we go into more detail about whether you should even break up your monolith). I base this on my own tried and true real-life experience as well as my work with the many Red Hat customers I’ve met over North America for the last few years.
