Disaster Recovery Architecture Diagrams

Generate disaster recovery architecture diagrams from plain English. Describe your primary environment, recovery targets, and replication strategy — ArchitectureDiagram.ai produces a complete DR architecture diagram with failover paths, RTO/RPO annotations, and recovery runbook steps.

DR patterns you can diagram

Active-active multi-region: Both regions serve live traffic; Route 53 or Cloudflare load balances between them. A failure reduces capacity without causing downtime. RTO ≈ 0.
Active-passive warm standby: Secondary region is pre-provisioned with a running (but idle) copy. Database replication is continuous. Failover takes minutes. RTO ≈ 5–30 minutes.
Pilot light: Only the core data replication is running in the DR region. The compute layer (EC2, ECS, Lambda) is scaled to zero and launched during a failover. RTO ≈ 15–60 minutes.
Backup & restore: Regular backups (RDS snapshots, S3 cross-region replication) are stored in the DR region. Recovery means restoring from the latest backup. RTO ≈ hours. Lowest cost.
Chaos engineering runbooks: Diagram the failure injection scenarios (AZ outage, database failover, traffic spike) and the expected system response for DR testing documentation.

Example DR diagram prompts

Active-passive RDS failover

"Primary region us-east-1: ALB → ECS Fargate cluster (3 tasks) → RDS PostgreSQL Multi-AZ. S3 bucket with cross-region replication to us-west-2. Secondary region us-west-2 (warm standby): ECS cluster scaled to 0, RDS read replica of primary. Route 53 health check monitors primary ALB; if it fails for 30 seconds, DNS failover points traffic to the us-west-2 ALB. RTO target: 10 minutes. RPO target: <1 minute (continuous replication). Show the replication arrows, health check, and DNS failover path."

Active-active global architecture

"Active-active deployment across us-east-1 and eu-west-1. Cloudflare load balancer routes users to the nearest region based on latency. Each region has: EKS cluster, Aurora PostgreSQL cluster (global database with write forwarding). Aurora Global Database replicates writes from us-east-1 (primary writer) to eu-west-1 (secondary) with <1 second lag. DynamoDB Global Tables replicate session data bidirectionally. If us-east-1 fails, eu-west-1 is promoted to primary writer in under 1 minute. Show both regions, the replication paths, and the promotion sequence."

Kubernetes DR with Velero

"Primary EKS cluster in us-east-1. Velero runs daily backups of all Kubernetes resources and PersistentVolume snapshots to an S3 bucket with cross-region replication to us-west-2. A secondary EKS cluster in us-west-2 is kept in a pilot-light state with only Velero and the ingress controller running. On a DR event, the on-call engineer runs velero restore in us-west-2, which restores all namespaces and reattaches volume snapshots. Estimated RTO: 45 minutes. ArgoCD in us-west-2 syncs app manifests from the same GitOps repo. Show the backup/restore flow, S3 replication, and recovery steps."

What to include in a DR architecture diagram

RTO and RPO labels: Annotate your DR diagram with Recovery Time Objective (how long before service is restored) and Recovery Point Objective (how much data loss is acceptable). These are the KPIs your architecture must meet.
Replication paths: Show database replication (RDS, Aurora, DynamoDB), object storage replication (S3), and message queue replication (Kafka MirrorMaker) as explicit arrows with direction and lag annotations.
Failover trigger: What detects the failure (Route 53 health check, CloudWatch alarm, PagerDuty alert)? Who or what initiates the failover (automated vs. manual operator decision)? Show this decision point explicitly.
Recovery steps: For active-passive and pilot-light patterns, document the ordered steps to bring the recovery environment live. Number them in the diagram.
Runbook references: Link your DR diagram to the runbook document. The diagram is the 30-second overview; the runbook is the step-by-step execution guide.

Incident commanders using DR diagrams as a reference during active outages

Frequently asked questions

What is a disaster recovery architecture diagram?

A disaster recovery (DR) architecture diagram visualizes how a system fails over to a secondary environment when the primary environment becomes unavailable. It shows the primary and recovery sites, replication mechanisms, failover triggers, RTO/RPO targets, and the steps required to restore normal operations.

What is the difference between active-active and active-passive DR?

In active-active DR, both primary and secondary environments serve live traffic simultaneously. A failure reduces capacity but doesn't cause downtime — RTO is near zero. In active-passive DR, the secondary environment is on standby and only activated during a failure. Active-active has the lowest RTO but costs roughly 2x; active-passive is cheaper but has higher RTO (minutes to hours).

How do I generate a disaster recovery diagram with AI?

Describe your primary architecture, your recovery site, the replication method (database replication, S3 cross-region, event streaming), your RTO/RPO targets, and any failover automation. ArchitectureDiagram.ai will generate a complete DR architecture diagram showing both sites, the replication paths, failover triggers, and recovery steps.
