Migration and Transfer

AWS Application Migration Service

Server migration service for replicating and launching source servers on AWS.

Key points

Application Migration Service replicates source servers and launches them on AWS for rehosting.
Test launches and cutover planning remain necessary before the replicated server becomes the production target.

Best-known use cases

Rehost servers that run legacy ETL or data applications on AWS.
Test replicated source servers before migration cutover.

What candidates often confuse it with

Application Migration Service rehosts servers; DMS migrates databases and DataSync moves files or objects.

Key takeaway

Choose Application Migration Service when legacy data-processing servers must be rehosted with minimal application change.
