Reliability Pillar - AWS Well Architected Framework
The foundation of a Disaster Recovery (DR) strategy involves backups, redundancy, and setting RTO and RPO based on business needs. Availability and Disaster Recovery share practices like failure monitoring and multi-location deployment, but Availability focuses on components, while DR focuses on the entire workload's recovery.
Best Practices:
⚪ Define Recovery Objectives: Establish RTO (acceptable downtime) and RPO (acceptable data loss) to guide your DR strategy.
⚪ Use Recovery Strategies: Implement strategies like backup/restore, standby, or active/active to meet recovery objectives and ensure preparedness.
⚪ Test DR Implementation: Regularly test failover and recovery plans to validate effectiveness and team readiness.
⚪ Manage Configuration Drift: Keep DR site configurations accurate and up to date using tools like AWS Config and CloudFormation.
⚪ Automate Recovery: Use AWS or third-party tools to automate system recovery and traffic routing, minimizing recovery time and errors.
