Question

How can you handle failures gracefully in orchestration workflows to ensure system reliability?

Orchestration workflows can encounter failures due to network issues, resource constraints, or unexpected system behavior. This question investigates techniques like retry policies, circuit breakers, fallback mechanisms, and monitoring to maintain reliability and ensure graceful degradation.

Answer 1

Retry Policies: Automate retries in case of temporary failures.

Circuit Breakers: When a service is unavailable, use circuit breakers to stop a chain reaction of failures.

Fallback Mechanisms: In the event that workflows malfunction, offer backup routes or default reactions.

Probes and Health Checks: Keep an eye on services to identify and replace any unhealthy ones.

Idempotency: Make sure that tasks are designed to be idempotent so that they won't cause problems when executed repeatedly.

Event Logging and Alerts: Monitor malfunctions and issue notifications so that prompt action can be taken.
