To design an event-driven architecture, you structure distributed systems using event sourcing, CQRS, and saga orchestration to ensure scalability and fault tolerance. This approach produces concrete design artifacts, validation steps, and rollback procedures based on your system context.

You need saga orchestration for microservices when managing complex distributed transactions and maintaining data consistency across multiple services. It coordinates sequences of local transactions, providing structured rollback procedures to handle failures and ensure system integrity without distributed locks.

The best way to implement CQRS and event sourcing is by separating read and write models while storing state changes as a sequence of immutable events. This pattern selection addresses scalability requirements and generates necessary design artifacts, configurations, and code stubs for your system.

Ensuring fault tolerance in event-driven messaging systems requires structuring your architecture with robust saga orchestration and validation steps. By addressing non-functional requirements during design, you generate specific rollback procedures and data consistency controls to handle distributed system failures gracefully.

Event-driven system design does not mandate specific messaging tools but guides the selection of appropriate messaging patterns and orchestration mechanisms based on your system context. The design process focuses on generating configurations and code stubs compatible with your chosen infrastructure to meet scalability requirements.
