A company runs a customer-facing application in the eu-west-1 Region. The application uses an Amazon Aurora MySQL database and stores user-uploaded files in an Amazon S3 bucket. The company has a disaster recovery plan that requires an RTO of 1 hour and an RPO of 15 minutes for the application. The application is stateless and can be re-provisioned from an AMI. The company wants to minimize the cost of the DR solution. Which strategy meets the requirements?

Use AWS Database Migration Service (DMS) to continuously replicate changes to an Amazon S3 bucket in eu-central-1. Restore from S3 during a disaster.

Enable Aurora Multi-AZ and rely on automatic failover to the standby in another Availability Zone.

Create an Aurora cross-Region read replica in eu-central-1. During a disaster, promote the replica to a standalone DB instance. Re-provision the application from the AMI and copy the S3 bucket to the DR Region.

Take daily snapshots of the Aurora DB cluster and copy them to eu-central-1. Restore the latest snapshot during a disaster.

A healthcare company runs a patient-records application on EC2 instances in the us-west-2 Region. The application stores data in an Amazon RDS for PostgreSQL DB instance. The compliance team requires that in the event of a regional disaster, the application must be available in the us-east-1 Region within 2 hours, and the maximum acceptable data loss is 15 minutes. The application is read-heavy, and the database is the only stateful component. Which solution meets the RTO and RPO requirements?
