Everyone is talking about event-driven architectures and streaming data. But people may not be actually using them successfully. If you haven’t started yet, you must learn to leverage the power of this approach. And even if you’ve already achieved a measure of success, you want to ensure your business’s viability and long-term flexibility in design that responds well to the inevitable ongoing change. And why stop at event-driven when your entire system can be reactive through message-driven architectures, both inside single services and across many collaborating services. This talk walks you through DDD context mapping with open host service and publish language and shows how to integrate using reactive implementations that transform streaming to well-designed solutions. Employing the right tools is key.
