The book mainly covers the breadth of technical knowledge required for a solution architect role. It provides details on solution architecture design principal and attributes such as scalability, high availability, performance, security, and cost. It further explains how to apply them in various design patterns such as microservices, event-driven, loosely coupled, queue-based, etc. It dives deep on different architecture pillars for architecture optimization and talks about details on workload automation with DevOps. It covers various aspects of data engineering and machine learning and skills to develop yourself as a solution architect. I found this book helpful for an aspirant solution architect to not only prepare for role bust also help them to crack SA interview as this is a conceptual book based on generalist solution architect, so not diving deep in one particular.
