- [Narrator] Think about the difference between architectural patterns and design patterns.

Design patterns are low-level and concrete. They are at the class level, and address how classes are instantiated, structured, and orchestrated. On the other hand, architectural patterns are high-level and abstract. They are at the module level and address global concerns, such as security, performance, maintainability, etc. By the way, these software qualities are also called quality attributes. Unlike its cousin, the impact of a design pattern is local. For example, a singleton focus is on limiting the number of objects instantiated from the same class, which…
