I read part of an early chapter of a book that taught a lot of these concepts in a practical way. The book isn’t out yet, but will be in the next month or so: https://pragprog.com/book/egmicro/practical-microservices

I think the code examples are out of date so don’t worry about downloading those until the book is officially released. This guy has had some great success stories implementing CQRS/Event Sourcing at his place of work in the last year.

Mark Nijhof has a CQRS book via Leanpub [1].

But I would suggest just read up and watch a little online and explore on your own. E.g any talks by Greg Young. The OP article has good further reading links. The pure concepts are simple. Implementations vary.
