Multi-Region (Multi-Site) with Route53
Route53 is one of the available services that will help to achieve an active-passive based failover which the mullti-site based disaster recovery model is about.
- Primary environment in us-west-1 and failover in us-east-1.
- If the primary site is discovered ‘Down’, it will automatically switch DNS to start using the secondary location.
- Target locations are NOT required to be hosted with AWS for this to work.
