Does anybody have good learning resources with regards to going into Event Driven Design, Architecture or Sourcing? I got recommended Eric Evans [“Domain-Driven Design: Tackling Complexity in the Heart of Software”](https://www.amazon.com/Domain-Driven-Design-Tackling-Complexity-Software/dp/0321125215) and have already watched Martin Fowler’s [talk](https://www.youtube.com/watch?v=STKCRSUsyP0) on the subject. Is there anything more literature I need to delve into before setting off my journey of events? ---

I was going recommended the same talk as I remb it was posted here: > **[Martin Fowler: The Many Meanings of Event-Driven Architecture • Keynote GOTO...](https://elixirforum.com/t/martin-fowler-the-many-meanings-of-event-driven-architecture-keynote-goto-chicago-2017-may-1/6738)** > > Martin Fowler (ThoughtWorks) outlines the differences, pros and cons of four major Event-Driven approaches: Event Notification Event-carried State Transfer Event Sourcing CQRS See also martinfowler.com: What do you mean by “Event-Driven”? ... This one by Elixir Forum member Ben Smith might also be worth a watch: [![](https://img.youtube.com/vi/3R3qeMr_ANE/hqdefault.jpg "Event sourcing in practice - Using Elixir to build event-driven applications") ](https://www.youtube.com/watch?v=3R3qeMr_ANE) He’s also writing a book, tho I’m not sure whether he still is as I’ve not seen him post any updates for a while: > **[Building Conduit - Applying CQRS/ES to an Elixir and Phoenix web app...](https://elixirforum.com/t/building-conduit-applying-cqrs-es-to-an-elixir-and-phoenix-web-app-self-published/6930)** > > I’m working on a CQRS/ES and Phoenix book for those interested in building an event driven application using Elixir. The full source code for the application, Conduit, is available on GitHub. ---

Recently I’ve read [O’Reilly Building Event-Driven Microservices](https://learning.oreilly.com/library/view/building-event-driven-microservices/9781492057888/) freely available in my local library via [OverDrive](https://www.overdrive.com/). You’ll learn: - How to leverage event-driven architectures to deliver exceptional business value - The role of microservices in supporting event-driven designs - Architectural patterns to ensure success both within and between teams in your organization - Application patterns for developing powerful event-driven microservices - Components and tooling required to get your microservice ecosystem off the ground ---

You could try the free book from Microsoft, [Exploring CQRS and Event Sourcing](http://download.microsoft.com/download/e/a/8/ea8c6e1f-01d8-43ba-992b-35cfcaa4fae3/cqrs_journey_guide.pdf). You might also try Greg Young’s [Versioning in an Event Sourced System](https://leanpub.com/esversioning/) which is free to read online. Greg [coined the terms](https://www.eventstore.com/blog/event-sourcing-and-cqrs) and was quite a vocal proponent of the pattern/architecture. ---

Event sourcing shares a foundation with transactions logs and so reading Jay Krep’s [The Log: What every software engineer should know about real-time data’s unifying abstraction](https://engineering.linkedin.com/distributed-systems/log-what-every-software-engineer-should-know-about-real-time-datas-unifying) might be helpful. You could also watch the “I Heart Logs: Event Data, Stream Processing, and Data Integration” [talk](https://youtu.be/SU8LaHLh6Ng) and/or read [the book](https://www.confluent.io/ebook/i-heart-logs-event-data-stream-processing-and-data-integration/) (for the cost of your email). ---

I am reading [https://www.cosmicpython.com/](https://www.cosmicpython.com/) now. It’s pretty well written. ---

The article posted here looks like it might be worth a read too… > [@What event sourcing is not about](https://forum.devtalk.com/t/what-event-sourcing-is-not-about/8693): > > For many developers, event sourcing is a magical beast that’s used to build extremely complex, often distributed projects. And there’s good reason for that: event sourcing is a pattern that forces code to be built in a way that fits those complex projects exceptionally well. Words like “modularized”, “distributed”, “scalable” and “versatile” come to mind to describe it; characteristics you can’t do without if you’re building applications at scale. Think about a popular webshop or a bank, handl…
