Case Studies: Pattern Selection

Welcome to the final mini-course! In microservices, choosing the right communication pattern is crucial for building robust and scalable systems.

This lesson explores real-world scenarios and helps you decide when to apply patterns like Saga, Circuit Breaker, Retry, or simpler methods.

Before diving into case studies, let's quickly recall the main patterns we've covered:

• Saga: Manages distributed transactions across multiple services.
• Circuit Breaker: Prevents cascading failures by stopping requests to unhealthy services.
• Retry: Automatically re-attempts failed operations.
• Asynchronous Messaging: Decouples services, allowing for non-blocking communication.

Each serves a distinct purpose.
