A city needs continuous block-level replication and orchestrated failover for lift-and-shifted VMs, not only periodic AMI copies. Which service should the architect select?
Select an answer to reveal the explanation.
Short Explanation
AMI photocopies are snapshots of yesterday’s desk; Elastic Disaster Recovery keeps a live block-level shadow you can fail over. Transfer Acceleration and weekly Snowball crates aren’t a VM DR control plane.
Full Explanation
AWS Elastic Disaster Recovery continuously replicates source servers at the block level into a staging area and supports failback/failover workflows suited to lift-and-shifted VMs. Periodic AMI copies alone typically leave larger RPOs and weaker orchestration. S3 Transfer Acceleration optimizes object transfers, and Snowball is for bulk offline data movement—neither replaces continuous VM replication and recovery orchestration required here.
