[5] The Software Engineering Institute author Paul Clemente found the first two volumes to be "the best-known catalog of architectural patterns". [6] Regarding the third volume, D. Murali recommended that software engineers should follow the "eager acquisition" pattern. [7]
Software architecture patterns operate at a higher level of abstraction than software design patterns, solving broader system-level challenges. While these patterns typically affect system-level concerns, the distinction between architectural patterns and architectural styles can sometimes be blurry. Examples include Circuit Breaker.

A set of architectural design decisions: software architecture should not be considered merely a set of models or structures, but should include the decisions that lead to these particular structures, and the rationale behind them. [10] This insight has led to substantial research into software architecture knowledge management. [11]
Software architecture pattern is a reusable, proven solution to a specific, recurring problem focused on architectural design challenges, which can be applied within various architectural styles. [ 1 ]
Often, no single optimal solution for any given set of architecture design problems exists. Architectural decision making is a core responsibility of software architects; [5] additional motivation for/of the importance of architectural decisions as a first-class concept in software architecture can be found online.

The hexagonal architecture, or ports and adapters architecture, is an architectural pattern used in software design. It aims at creating loosely coupled application components that can be easily connected to their software environment by means of ports and adapters. This makes components exchangeable at any level and facilitates test automation ...
An architectural model (in software) contains several diagrams representing static properties or dynamic (behavioral) properties of the software under design. [1] [2] [3] The diagrams represent different viewpoints of the system and the appropriate scope of analysis. The diagrams are created by using available standards in which the primary aim ...
Architecturally significant requirements are used in software design to drive and justify architectural decisions; if not satisfied properly, they contribute to the accumulation of technical debt. For instance, failure to meet security and compliance requirements complicates the system and process assurance audits and increases the risk of ...
