Imagine a world in which you could build a distributed system that guarantees that every individual user action travels throughout a multitude of services without ever being lost or duplicated. No lost orders. No duplicate entries that require reviews. No persistent exceptions due to data inconsistencies.

If you're imagining rainbows and unicorns right now, this session is for you!

Before going into specifics, we need to stop thinking about message delivery and focus on message processing instead. We'll explore an end-to-end approach to message processing, starting from the human-to-machine interaction in the front end of the system and traversing component-to-component message-based communication throughout the system.

As a cherry on top, I'll present you with a fully operable example showcasing cross-system, exactly-once, HTTP-based communication.
