Workshop: Building a scalable backend with Akka.NET - 2/2

Module 3/4

If you’re developing something that has the potential to explode in usage, you’re going to need to be able to scale the resources of your backend when your business takes off. It doesn’t matter if it’s an IoT device, a smartphone app, an Alexa skill or a video game. And if Amdahl’s law teaches us anything, it is that to do that successfully in a stateful system, you are going to need high degrees of parallelization.

Akka.NET, and its implementation of the actor model, promise you just that: highly parallelizable code that scales beautifully as machines are added to the cluster. But there are more advantages than just scaling. Actor models can make your backend very robust, because of their self-healing nature. The code is also easy to reason about, and easy to test.

But the patterns for designing such a system are different from what you might be used to writing object-oriented code. And there are a few pitfalls that you might want to avoid altogether.

During this workshop, you will build your own backend for dealing with the meter readings coming from an electricity meter. Everything from ingesting large quantities of data, over shaping and cleaning your data, storing it, and generating alerts under certain conditions. You will not need any knowledge about Akka.NET to attend this workshop. All concepts are handled during the course.

All the concepts you will encounter will be just as valuable in building other types of backend systems as well.
