Handle AWS control plane failures by implementing standard retry patterns with exponential backoff and a hard deadline. This time-bound approach limits retries during outages, preventing automated workflows from entering infinite loops while waiting for unresponsive services.

Control plane fallbacks manage resource configuration and lifecycle, while data plane fallbacks handle ongoing data operations. During an outage, separating them allows workflows to switch to data plane operations when control plane APIs are unresponsive.

Configure exponential backoff by setting a deterministic retry policy with a hard deadline for EC2, RDS, and S3 APIs. Use environment-based configuration to adapt retry limits, then switch to data plane fallbacks if the control plane remains impaired.

The best way to implement cross-region failover is using time-limited retry logic for Lambda and ECS/EKS, then applying recommended fallback patterns. This ensures operational continuity by switching to alternative regions when the primary control plane is degraded.

Use data plane fallbacks when AWS API calls fail, time out, or return 5xx errors after hitting the hard retry deadline. Switching to data plane operations ensures workflows continue functioning despite an unresponsive or impaired control plane.
