AWS Elastic Disaster Recovery can be improved through regular drills to ensure that all resources are properly prepared for disasters with scheduled drills. This includes testing and understanding failback, which is crucial for a comprehensive disaster recovery plan. Monitoring and health checks are important to continuously monitor the health of the ongoing replication using the AWS Elastic Disaster Recovery console or programmatically. This helps identify any servers that may require attention and ensures that the application is functioning correctly. Creating a CloudFormation template that can create the necessary network resources on demand is useful for disaster recovery. There should be documentation and best practices guidance so that teams can follow best practices for implementation and maintenance of disaster recovery from on-premises using AWS. This includes a written recovery plan as well as regularly updating it with findings and required changes. Within the scope of improvements, there are many possibilities, but it is currently providing some great results. The scope of improvements can include monitoring and health checks as well as documentation with best practices for documentations, and conducting regular drills.
