Chapter 9 Application Architecture

The output will be the counter increasing. If we stop and relaunch the application, you will notice that the counter did not start from zero again; it saved its state in Redis across restarts.

Figure 9-11.  The Dapr sidecar model

This was just one very simple example of Dapr. The major advantage is that Dapr takes a bunch of components and principles and bundles them into one developer model. We only need to develop against the Dapr API; everything else is handled by the runtime.

Wrapping Up

.NET has always been a framework that promotes good, clean architectures, and it continues that trend with .NET 6. Open-source reference projects like eShop On Containers help guide developers and application architects in finding the best architecture for their projects. Frameworks like Dapr can help ease the struggles of

managing all the different building blocks in distributed applications. But as always, there is no one-size-fits-all. Look at the project you want to build from a higher, abstracter place, and choose the right architecture for the job. Not everything is suited for a complex DDD setup; don’t overengineer but keep things simple.
