What is a software architecture pattern?

A software architecture pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. These patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. Software architecture patterns serve as templates, allowing developers to apply them in various situations as opposed to one-time designs tailored to a specific problem. By employing these patterns, developers can avoid commonly known pitfalls and improve the efficiency and reliability of their software. Examples of software architecture patterns include the Model-View-Controller (MVC) pattern, which separates an application into three main components; the microservices architecture, which structures an application as a collection of loosely coupled services; and the layered architecture pattern, which organizes applications into layers with specific roles and responsibilities.
