Akka.net VS wasmCloud

akka.net actors. Actors all the way! https://getakka.net

If it's the former you may want to take a look at something like the actor model akka.net with persistent actors (https://getakka.net/articles/persistence/architecture.html). No need of an external message broker or mass transit (which is a wrapper over different message brokers). You could use sqllite for persisting the actors state to recover in case of a restart.

Spring and Hibernate are the goto libraries in Java land and I suspect that's the primary motivation for your colleague's recommendations. It's quite easy to bulldoze someone less experienced with your ideas so be careful of that. I'd avoid both. They aren't bad libraries at all but they have a 'legacy' feel and it will make your application less future proof. Would a distributed system be viable? If so then I'd recommend Akka, there'a .NET port of it that's well supported and maintained.

Is akka a good alternative?

However, I've found that sometimes, they are a little -too- functional. I'm a bit more preferential to Akka.Net's implementation of Option and Try, if only because they have good 'escape hatches' where you interrogate them in a more procedural manner.

This project is also what ultimately led to the creation of Akka.NET - I wrote an overview on how our application was built here: https://aaronstannard.com/markedup-akkadotnet/

You may also want to take a look at queues (e.g. RabbitMQ) or even something like Akka.NET or Microsoft Orleans.

From the title I immediately thought AKKA.NET or Orleans

There’s a lot more to go into there, but you may find https://wasmcloud.dev interesting 🙂

The wasmCloud project (https://wasmcloud.dev) has a number of areas where people can contribute. As someone else said, you can filter on "good first issue" to get an idea for what needs doing.

Webassembly is also gaining steam for server workloads due to several advantages (less overhead, better capability based security, composability, ...).

See Spin [1], Wasmcloud [2], Lunatic [3], etc.

My system is based on a distributed Webassembly runtime.

The reason for taking inspiration from Kubernetes is making deployment of distributed workloads on that runtime easy.

A nice benefit for a Kubernetes alike system is that the equivalent to controllers can be much more light-weight WASM actors that are easier to deploy and scale.
