spring-petclinic VS eShopOnContainers

Here is a good repository to look at as you make progress. Good luck!

I like Spring's petclinic https://github.com/spring-projects/spring-petclinic

For the sake of demonstration, I'm going to use the same project I've used in my post about Omnipytent - the Java Sprint example project PetClinic.

"The Spring Pet Clinic" is well explained and obviously well designed and coded as an official Spring projet : https://github.com/spring-projects/spring-petclinic

For this OpenTelemetry Java example, we’ll be using the Spring Pet Clinic project, to save you some time setting up an example project.

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?
