Disaster Recovery Plan Implementation

Every DR plan starts with numbers: how much data can you afford to lose (RPO) and how long can you be down (RPO). We map each service in your stack to concrete RTO/RPO targets based on business impact analysis. A payment service gets sub-minute RPO with synchronous replication. A reporting dashboard tolerates 24-hour RPO with daily snapshots. These targets drive every architecture decision that follows.

We implement failover at every layer — DNS-level failover with health checks (Route 53, Cloudflare), database replication with automated promotion (PostgreSQL streaming replication, RDS Multi-AZ), and application-level circuit breakers. For Kubernetes workloads, we configure multi-cluster federation or Velero-based cluster restore. Each failover path gets automated with scripts that run in under 60 seconds.

Every failure scenario gets a step-by-step runbook: primary database fails, entire AZ goes down, DNS provider outage, certificate expiration. Runbooks include exact commands, expected outputs, rollback steps, and escalation contacts. These are executable documents — not aspirational wikis that nobody reads during an actual incident.

We schedule quarterly DR drills. Full failover to secondary, timed recovery from backup, and chaos engineering scenarios. Each drill produces a report: actual RTO vs target, data integrity verification results, and a list of gaps to remediate. If your DR plan has never been tested, it does not exist. We make sure it works before you need it.
