What You'll Learn​

  • Anti-pattern 1: Synchronous cross-region calls, 100-200ms latency added, cascading timeouts
  • Anti-pattern 2: Ignoring data affinity, $12K → $95K monthly data transfer costs
  • Anti-pattern 3: Insufficient DR testing, discovering broken runbooks during actual outage
  • Anti-pattern 4: Shared fate dependencies, IAM/Route53 in us-east-1 single points of failure
  • Anti-pattern 5: Over-engineering, hot-hot when hot-warm sufficient, 7.5x cost without matching business requirement
  • Anti-pattern 6: Missing observability, blind during failover, cross-region tracing essential
