I liked how the book dove into the higher level concepts of serverless but also gave implementation and code examples. Most architecture books I’ve read leave me with conceptual knowledge and no practical examples. Also brought things back to the evidence based SDLC approach described in accelerate, showing how this architecture can help improve DORA metrics.
One thing i wish the book did, is talk more about what level of organizational scale these concepts start to pay off at. Some of the concepts like microfrontends have a lot of engineering overhead, to make sure all the micro-apps can integrate well together, etc. In a typical organization focused on rapid feature delivery, I would be curious to hear more about how much engineering time and resources is allocated horizontally across teams maintaining some of that glue, who owns it, etc.
