I recently published a post on the Carbon Five blog titled “Evented Rails: Decoupling complex domains in Rails with Domain Events” that takes some of my thoughts about moving a Rails app to use Domain Events - leveraging the power of Sidekiq (or your job runner of choice) to send async messages between different domains of your app.
One common pattern in Domain-Driven Design is the use of publish/subscribe messaging to communicate between domains. When Domain Events are created from within a domain, other domains are able to subscribe to these events and take action within their own domains, respectively.
I want to discuss a topic near and dear to my heart, and what I believe is at the crux of effective software design. It’s not a new functional language, it’s not a fancy new framework, a how-to guide to do microservices, nor a quantum leap in the field of machine learning.

In recent conversations with coworkers, the topic of Domain-Driven Design has arisen on more than a few occasions in design and architecture meetings. “Have you read it?” a coworker asked, “I think it’d help us a lot.”
