Description:
The Fallback design pattern is a resiliency pattern used in microservices architecture to handle failures gracefully. It ensures that when a service is unavailable or fails, the system can continue to operate by providing an alternative response or executing a predefined fallback mechanism. This pattern enhances the robustness and reliability of microservices by preventing cascading failures and improving the overall user experience.
Main Elements of the Pattern:
Service Degradation: Provides a simplified version of the service or a cached response to maintain functionality.
Fallback Handlers: Defines alternative methods or responses when the primary service call fails.
Circuit Breaker Integration: Often used in conjunction with the Circuit Breaker pattern to monitor service health and redirect to fallback handlers when necessary.
Timeout Management: Configures timeouts for service calls to ensure quick fallback execution.
Resilience and Fault Tolerance: Enhances the system's ability to withstand failures without significant disruption.
