"organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations."
This sentence shows the relevance of the way people organize to develop systems, and how this impacts every design decision we make. We will get into depth in the later chapters discussing microservices architectures, about how we can decouple and remove the barriers that prevent systems from evolving. Bear in mind that this book will show you a new way of systems thinking, and with AWS you have the tools to solve any kind of problem and create very sophisticated solutions.
