AWS drs documentation change
Summary
Added a 'Key terminology' section to clarify the distinction between Recovery, Recovery drill, Failover, and Failback. Updated overview and section titles for accuracy.
Security assessment
The change is purely a documentation clarification to define service terminology and correct a section title from 'Preparing for failover' to 'Preparing for recovery'. It provides no new information about security features, vulnerabilities, or security-related procedures. There is no evidence of a security issue being addressed.

Recovery creates new Amazon EC2 instances from your replicated data. + +Recovery drill + + +A non-disruptive test that launches drill instances to validate your disaster recovery readiness. Drills use the same process as recovery but do not affect your source servers or ongoing replication. + +Failover + + +The act of redirecting production traffic from your primary (source) environment to your recovery instances on AWS. Failover is performed outside of AWS Elastic Disaster Recovery, typically using a DNS routing service such as [Amazon Route 53](https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/Welcome.html) or your organization's traffic management solution. + +Failback + + +The process of returning your workloads from the recovery environment on AWS back to your original source infrastructure after the disaster has been resolved.
