Step 4: Review failure mode findings and recommendations - AWS Resilience Hub

Step 4: Review failure mode findings and recommendations

Once the assessment completes, review the results to understand the potential failure modes in your service and the recommended improvements.

Console:

  1. Navigate to your service and choose the Failure modes tab.

  2. Review findings sorted by severity.

  3. Choose any finding to see detailed reasoning and recommendations.

AWS CLI:

aws resiliencehubv2 list-failure-mode-findings \
  --service-arn "arn:aws:resiliencehub:us-east-1:123456789012:service/api-service:def456"

Understanding your findings

Each finding tells you:

  • What the failure mode is (for example, "Single-AZ RDS database").

  • Why it matters for your architecture.

  • How to fix it, with recommendations that include cost and complexity considerations.

  • Which policy requirement it relates to.

Taking action

For each finding, you can:

  • Reason – Think about the failure mode in detail and reason about the likelihood and impact of it occurring.

  • Fix it – Implement the recommendation if the likelihood and impact warrant it, then re-run the assessment to verify.

  • Mark as irrelevant – Suppress the finding if it does not apply to your use case. Suppressed findings remain suppressed across future assessments.

  • Prioritize – Use severity to decide what to address first.
