Frequently Asked Questions

What are software architecture patterns?

Architecture patterns are proven, reusable solutions to recurring structural problems in software systems, such as how to layer a codebase, separate reads from writes or keep services resilient to failure.

How do architecture patterns differ from design patterns?

Architecture patterns shape the overall structure of a system or service, while design patterns solve smaller, code-level problems inside it. See the Software Design Patterns page for the code-level view.

Which patterns are most used in cloud systems?

Layered and hexagonal structure inside services, plus CQRS, event sourcing, saga, circuit breaker, sidecar, backends for frontends and the strangler fig for migration.

Where should I start?

Start with a catalog such as the Azure Architecture Center patterns or Martin Fowler's architecture guide, then read the original articles for hexagonal and clean architecture.
