Executive Summary
This document outlines Goodworld's comprehensive disaster recovery (DR) strategy, designed to ensure business continuity in the event of a regional infrastructure failure. Our architecture leverages AWS's global infrastructure with a multi-region deployment approach, providing robust failover capabilities and minimal data loss potential.
Recovery Objectives
Recovery Time Objective (RTO): 1 hour
Recovery Point Objective (RPO): 15 minutes
These objectives reflect our commitment to maintaining business continuity while minimizing potential data loss in disaster scenarios.
Infrastructure Overview
Geographic Distribution
Our infrastructure is strategically distributed across multiple AWS regions:
Primary Region: US-East-1 (Virginia)
DR Region: US-West-2 (Oregon)
Content Delivery: Global CloudFront distribution network
Data Replication: Cross-region synchronization between primary and DR regions
