Architectural styles describe recurring high-level system structures. They are useful because they:

• give you a vocabulary to communicate architecture;
• suggest typical non-functional requirement trade-offs;
• guide decomposition and deployment decisions.

This course covers the following architectural styles. For each style, we introduce its topology with diagrams, pros and cons, potential variants, and pointers to real-world examples.

• Pipe-Filter
• Layered
• Repository
• Implicit Invocation
• MVVM (MVC, MVP)
• Server-Client (Microservices, Serverless)
• Process-Control

Many examples are chosen from The Architecture of Open Source Applications.
