AWS Disaster Recovery Strategies

Author

Pascual Vila

Cloud Instructor.

Disaster Recovery (DR) is a set of policies, tools, and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster.

DR Strategies

AWS provides several DR strategies: Backup and Restore (lowest cost, longest RTO), Pilot Light (minimal infrastructure running), Warm Standby (scaled-down version running), and Multi-Site Active/Active (full production in multiple sites).

RTO and RPO

RTO (Recovery Time Objective) is the maximum acceptable time to restore service after a disaster. RPO (Recovery Point Objective) is the maximum acceptable amount of data loss measured in time.

AWS Services for DR

AWS services for DR include S3 for backups, EBS snapshots, RDS automated backups, Route 53 for DNS failover, CloudFormation for infrastructure as code, and AWS Backup for centralized backup management.

Disaster Recovery Glossary

Disaster Recovery (DR)
A set of policies, tools, and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster.
RTO (Recovery Time Objective)
The maximum acceptable time to restore service after a disaster. Lower RTO means faster recovery.
RPO (Recovery Point Objective)
The maximum acceptable amount of data loss measured in time. Lower RPO means less data loss tolerance.
Backup and Restore
A DR strategy with the lowest cost but longest RTO. Data is backed up and restored when needed.
Pilot Light
A DR strategy where minimal infrastructure is running in the DR region, ready to scale up quickly.
