A legacy on-premises app cannot be rewritten soon, but the city must improve reliability in AWS while planning a later migration. Which approach fits Associate-level constraints?
Select an answer to reveal the explanation.
Short Explanation
You don’t have to rebuild city hall to add fire exits—put the legacy app on multi-AZ EC2 behind an ALB, snapshot the disks, and plan the rewrite later.
Full Explanation
Reliability for legacy workloads can improve without code changes by placing instances in multiple AZs behind an ALB and using EBS snapshots or AWS Backup for recovery. Blocking all HA pending a rewrite, single-IP exposure, or dropping backups undermines interim resilience.
