I wish more of those tutorials and books would cover the synchronization and communication between services using RabbitMQ. I have not read extensively enough on the matter, but it seems like it's a much better fit that helping entities communicate than HTTP.
I'm going to spoil: Practical Microservices will cover synchronous communication with both HTTP and AMQP (RabbitMQ and friends), as well as async with AMQP.
Among other benefits sync over AMQP provides is the fact that you don't really need a service discovery mechanism because interested service will find & serve your request itself. It also means that you won't need to put the services behind a firewall or implement some sort of inter-service auth (when firewall isn't an option, read: Heroku), because nothing is exposed to the web.
Will definitely get into it more deeply in Practical Microservices. Stay tuned!
We took "Show HN" out of the title, because Show HNs are for things you've made that other people can play with. In the case of a book, "play with" can only mean reading the actual book. So this will make a good Show HN when the book is ready. Good luck!
