The document discusses architectural decisions when building distributed systems. It notes that architecture refers to "stuff that's hard to change" and identifies three main categories of distributed system architectures: active/sync, CQRS message-driven, and reactive/event-driven. The document concludes by recommending that developers check their product stage, team size, team experience, ask an expert, and to design systems using lean and agile principles.
