Understanding the topology, rationale, and tradeoffs for common architecture styles is a critical foundational skill for architects. Additionally, architects need to know when to use synchronous or asynchronous communication patterns. This online course takes modern engineering practices and perspectives and applies it to a survey of architecture patterns. For each pattern, I discuss the history, philosophy, rationale, topology, optimum uses, and negative tradeoffs. I also discuss common communication patterns within particular styles, along with pros and cons for the architecture style.
