Planning Disaster Recovery

Overview

Design disaster recovery (DR) plans for cloud infrastructure covering RTO/RPO requirements, multi-region failover, data replication, and automated recovery procedures. Generate runbooks, Terraform for standby infrastructure, and automated failover scripts for databases, compute, and networking.

Prerequisites

Complete inventory of production infrastructure components and dependencies
Defined RTO (Recovery Time Objective) and RPO (Recovery Point Objective) per service tier
Cloud provider CLI authenticated with permissions for multi-region resource management
Cross-region networking configured (VPC peering, Transit Gateway, or VPN)
Backup and replication mechanisms already in place or planned

Instructions

Catalog all production services with their criticality tier (Tier 1: < 15 min RTO, Tier 2: < 1 hour, Tier 3: < 24 hours)
Map dependencies between services to identify single points of failure and cascading failure paths
Design the DR strategy per tier: active-active for Tier 1, pilot light or warm standby for Tier 2, backup-restore for Tier 3
Generate Terraform for standby region infrastructure: VPC, subnets, security groups, and scaled-down compute
Configure database replication: RDS cross-region read replicas, DynamoDB global tables, or Cloud SQL cross-region replicas
Set up DNS failover using Route 53 health checks, Cloud DNS routing policies, or global load balancers
Create automated failover scripts: promote read replica to primary, update DNS records, scale up standby compute
Document the DR runbook with step-by-step procedures, responsible parties, and communication plans
Schedule quarterly DR drills: simulate region failure, execute the runbook, measure actual RTO/RPO, and document gaps
Set up monitoring for replication lag, backup freshness, and standby infrastructure health

Output

DR plan document with service tiers, RTO/RPO targets, and recovery procedures
Terraform modules for standby region infrastructure
Automated failover scripts (database promotion, DNS switching, compute scaling)
DR drill checklist and post-drill assessment template
Monitoring dashboards for replication lag and backup status

Error Handling

Error	Cause	Solution
`Replication lag exceeds RPO`	Network throughput insufficient or write volume too high	Increase replication instance size, enable compression, or implement write throttling during peak
`DNS failover not triggering`	Health check misconfigured or TTL too high	Verify health check endpoint returns proper status; reduce DNS TTL to 60 seconds before drill
`Standby database promotion failed`	Replication broken or standby in inconsistent state	Check replication status; if broken, restore from latest snapshot and re-establish replication
`Insufficient capacity in DR region`	Instance types unavailable in standby region	Pre-provision reserved capacity in DR region or use multiple instance type options
`Application cannot connect after failover`	Connection strings hardcoded to primary region endpoints	Use DNS-based endpoints (CNAME/Route 53) instead of direct IPs; parameterize region in config

Examples

"Create a disaster recovery plan for a 3-tier web application on AWS with < 15 minute RTO for the API layer and < 1 hour for batch processing."
"Generate Terraform for a warm standby in us-west-2 with RDS cross-region read replica, scaled-down ECS cluster, and Route 53 failover routing."
"Design a DR drill that simulates primary region failure, executes automated failover, and validates data integrity in the standby region."
