Part 6/10:
Failover Routing
Implement weighted routing with DNS or load balancers to automatically switch to backup systems in case of primary system failure.
Autoscaling & Auto-Healing
Use autoscaling groups and auto-healing mechanisms to handle spikes and recover from failures without manual intervention.
Pattern Implementations
Circuit Breaker Pattern: Prevents system overload by cutting off requests to failing services.
Backoff and Retry: Implement exponential backoff strategies to handle transient failures smoothly.
Write-Ahead Logging: Ensures data consistency and recovery in case of crashes.
