CAP VS docs

You might want to implement the outbox pattern. There’s a decent library that’ll help and is really easy to integrate. In particular, I’d look at using the transaction functionality

This might be of interest https://cap.dotnetcore.xyz/

There are many libraries in .NET that helps you implementing the outbox pattern like: MassTransit, NServiceBus, CAP. Talking about idempotency, a special mention to a specific lib from a big friend that runs on top of CAP which is called Ziggurat.

Correct but I would actually consider CAP instead. The primary reason is that CAP implements the outbox pattern out-of-box where you would need to implement this yourself with Hangfire.

I agree with the general sentiment here that you should try to keep things simple as long as possible. In addition to that, try to use frameworks such as Dapr, that allow you to postpone certain architectural decisions. Since Dapr runs everywhere where Kubernetes runs, it doesn't really matter which cloud provider you pick. Also, when it comes to pub/sub brokers, state stores, or secret stores, when using Dapr components you can easily swap those out.

I'm mostly familiar with orchestration type sagas, and there I usually include retries when calling services and compensation actions in case calls completely fail. It really helps if you're using a framework, such as Dapr, to do most of the heavy lifting. You can apply resiliency policies to service calls and with the latest version, there's now a Workflow API to orchestrate your services.

One other option that is worth mentioning is Dapr. Dapr is a microservices building block that developers can use to develop microservices. There is a bit of overlap between Dapr and service meshes and the Dapr team has done a good job of comparing the two here. The biggest takeaway when comparing the two is that Dapr does not provide traffic routing/splitting. So if you need these capabilities, then yes, you will need a service mesh.

There was a similar issue with the code examples to get/set state, so I created a GitHub issue for them.

It is an Image Recognition Application made using Go Language, works on a Tensorflow model and it requires Dapr and WasmEdge runtime for execution.
