List of software architecture styles and patterns

Software Architecture Pattern refers to a reusable, proven solution to a recurring problem at the system level, addressing concerns related to the overall structure, component interactions, and quality attributes of the system. 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.

Software Architecture Style refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions. Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for interpreting the system's properties. These styles represent the most coarse-grained level of system organization. Examples include Layered Architecture, Microservices, and Event-Driven Architecture.

• Event-driven architecture
• Hexagonal Architecture (also known as Ports and Adapters)
• Layered architecture
• Microkernel architecture
• Pipes and Filters architecture
• Microservices
• (Modular) monolithic
• Service-oriented architecture
• "Service-based architecture"
• Space-based architecture

• Inbox and outbox pattern
• "Queue-Based Load Leveling", also known as the "Storage First Pattern", is an architectural pattern in which a queue acts as a buffer between an invoker service (such as an API Gateway) and the destination (e.g., compute resources).
• "Backends for frontends" pattern
• "Public versus Published Interfaces"
• Asynchronous messaging
• Batch request (also known as Request Bundle pattern)
• Blackboard (design pattern)
• Client–server model
• Competing Consumers pattern
• Model–view–controller
• Claim-Check pattern
• Peer-to-peer
• Publish–subscribe pattern
• Rate limiting
• Request–response
• Retry pattern
• Rule-based
• Saga pattern
• Strangler fig pattern
• Throttling
