AWS Architecture Decisions
Good architecture begins with the constraints. Then comes the decision—and the reason behind it.
Choose a useful starting point.
Start with Volume I for architecture, data, AI and security. Choose Volume II when your focus is cost, migration, resilience or operations. Together, the two books contain 25 chapters and 398 original study questions.
Read a worked scenario, explain the constraints and alternatives, then check your reasoning against the rationale and current AWS documentation.
