Design for Failure with Graceful Degradation

This standard mandates designing systems for failure with graceful degradation to ensure functionality even when components fail.

1. Design for Failure with Graceful Degradation:

Ensure systems remain functional even when components fail. This approach ensures resilience and maintains user experience during outages.

• 1.1 Failure Mitigation Mechanisms:
  • 1.1.1 Circuit Breakers and Retries:
    • Implement circuit breakers, retries, and failover mechanisms.
    • Automate the configuration of circuit breakers.
  • 1.1.2 Failover Implementation:
    • Automate the implementation of failover mechanisms.
    • Implement failover tracking.
• 1.2 Fallback Strategies:
  • 1.2.1 Cached Content Serving:
    • Use fallback strategies (e.g., serving cached content when a service is unavailable).
    • Automate the management of cached content.
  • 1.2.2 Strategy Implementation:
    • Automate the implementation of fallback strategies.
    • Implement strategy feedback collection.
• 1.3 Dependent Service Isolation:
  • 1.3.1 Outage Prevention:
    • Ensure dependent services do not cause a full system outage.
    • Automate the monitoring of dependent service impact.
  • 1.3.2 Isolation Management:
    • Automate the isolation of dependent services.
    • Implement isolation tutorials.

By designing for failure with graceful degradation, organisations can ensure system resilience and maintain user experience.
