Implement AWS Elastic Disaster Recovery for the EC2 instances, establish a cross-Region read replica for the RDS database, deploy an ALB in a secondary AWS Region, set up an AWS Global Accelerator endpoint linked to the ALBs, and update the DNS records to direct traffic to the Global Accelerator endpoint.

Utilize Amazon Data Lifecycle Manager (DLM) for the EC2 instances to automate EBS volume snapshots, enable RDS automated backups, replicate backups to a second AWS Region, set up an ALB in the secondary Region, configure an AWS Global Accelerator endpoint associated with the ALBs, and modify the DNS records to point to the Global Accelerator endpoint.

Develop a backup plan in AWS Backup for the EC2 instances and RDS database, replicate backups to a second AWS Region, establish an ALB in the secondary Region, configure an Amazon CloudFront distribution in front of the ALB, and update the DNS records to direct traffic to CloudFront.

Employ Amazon Data Lifecycle Manager (DLM) for the EC2 instances to manage EBS volume snapshots, create a cross-Region read replica for the RDS database, set up an ALB in a secondary AWS Region, establish an AWS Global Accelerator endpoint connected to the ALBs, and update the DNS records to point to the Global Accelerator endpoint.
