This project shows how to apply more complex patterns popular in business applications while staying true to the Go ideas, and not copying them blindly from Java.

In the Go community, you’ll often hear people say „just keep things simple” beats all patterns and is all you need. This may be true if you write a CLI tool or a small library, but if you have a team maintaining a big application, some patterns are super helpful.

Here is a reference implementation by the same authors of the blog post you referenced: https://github.com/ThreeDotsLabs/wild-workouts-go-ddd-example/tree/master/internal/trainer.

In this case I recommend Three Dots Labs blog and Ardan Labs courses and blog posts.

As a rather new developer, I'm ashamed to admit that I struggle with this. I've seen the Dave Cheney writeup about it and I agree with your reasoning, but sometimes I end up in situations like this, where they wrote a server utility, put it into the common package and imported it into the services that need it. The issue I have is the organization of it all because the folder structure seems to make a clear separation of the core services from the utility package. If you have any ideas or tips to help avoid it, that'd be awesome!

Clean architecture is not tied to some specific paradigm. It's a way of thinking about programs that is common to almost every mature developer. Many developers use it without even knowing the name - they just came to it by themselves through many tries and errors. There is a good free book about using it in Go, called Go with the Domain if you interested.

Wild Workouts should match your needs: https://github.com/ThreeDotsLabs/wild-workouts-go-ddd-example

For Event-Driven / DDD / Microservice projects, take a look at this Github org https://github.com/ThreeDotsLabs and their blog detailing the techniques used https://threedots.tech .

Nice job at taking a stab at DDD in Go! You may want to check out https://github.com/ThreeDotsLabs/wild-workouts-go-ddd-example for some inspiration and learning around DDD and Go.

The eShopOnContainers is pretty popular, have you seen it yet? https://github.com/dotnet-architecture/eShopOnContainers

so I was exploring eShopOnContainers a little bit, more specifically the messages queues part and it made me wonder how is it possible to ensure data consistency across microservices when using them. If I'm not mistaken this isn't even shown in the eShopOnContainers examples.

For an example of an aggregate if you're unfamiliar - https://github.com/dotnet-architecture/eShopOnContainers/blob/3169a933447f1013c069e2cad2805c5de1ce9fbf/src/Services/Ordering/Ordering.Domain/AggregatesModel/OrderAggregate/Order.cs

You can check out eShopOnContainers as a reference architecture if you want, but (assuming this is meant to be somewhat of an ad hoc solution rather than a paragon of software engineering) I'd minimize the number of deployable assemblies (1 + tests if possible) and avoid Docker, again unless you have a specific reason to use it.

For K8s, it has a whole directory with deployment scripts. https://github.com/dotnet-architecture/eShopOnContainers/tree/dev/deploy/k8s

Checked the eshop on containers which uses EF for writes with DDD. Queries uses Dapper with raw sql. https://github.com/dotnet-architecture/eShopOnContainers/blob/dev/src/Services/Ordering/Ordering.API/Application/Queries/OrderQueries.cs

Maybe Microsoft’s eShopOnContainers reference system?
