Back to Basics: Disaster Recovery on Regional Databases

Learn a well-architected disaster recovery pattern for your Amazon Aurora databases across multiple AWS regions. Join Shailaja as she covers key concepts like Availability Zones, Regions, RTO, and RPO to help you ensure high availability and minimize data loss during outages.

Learn how to provision your application and Aurora databases across primary and secondary regions, using read replicas and Amazon Route 53 for seamless failover. See how you can instantly promote a secondary cluster to become the new primary with full read/write capabilities in under a minute!

Avoid the anti-pattern of provisioning databases just across AZs - that won't protect you from regional failures like earthquakes. Implementing cross-region disaster recovery as prescribed by AWS gives you resilience against isolated faults or region-wide service disruptions.

Get back to basics with this essential architecture pattern for robust database disaster recovery on AWS.

Why is one region called primary and the other secondary? Is the secondary region only getting traffic if the primary one becomes unreachable?
