AWS Migration & Synchronization Tools
Online
need internet
- AWS DataSync: Realtime sync
- AWS Transfer Family: based on SFTP/FTP/FTPS, async
- AWS Database Migration Service (DMS)
- one-time migration
- continuous replication (CDC, Change Data Capture)
- AWS Application Migration Service (MGN), async
- Formerly CloudEndure Migration
- scenario:
- Agent installed at origin server
- Step-by-step replication
- Supports rollback if target location fails
- AWS Storage Gateway: hybrid cloud, sync
- Volume Gateway: iSCSI block storage
- File Gateway: NFS/SMB
- Tape Gateway: iSCSI VTL
Offline
Just Snow Family

- Snowcone 8 TB HDD
- Snowball
- storage optimized 80 TB HDD
- storage optimized 210 TB SSD NVMe + 104 vCPU
- compute optimized 28 TB SSD + 104 vCPU
- Snowmobile：100 PB, EB-level
Related Services (but not that Precise)
minimal network connection
- AWS Backup
It does not rely on real-time compute resources or the continuous involvement of online services.
- AWS VM Import/Export
VM Import/Export is simply to convert VM images to AMI and handle the uploading and downloading of files.
It does not require the involvement of other AWS services.
- AWS Server Migration Service (SMS)
- batching migration
Offline migration usually means there’s no need for real-time synchronization, but it still carries the meaning of migration. Some steps might go through the network, but the focus isn’t on synchronization, so I categorize it as offline migration.
Migration helpers
Infrastructure-focused, similar to online tools but emphasizes network infrastructure
- AWS Direct Connect: Dedicated connection line
- VPN: Encrypted tunnel
Specialized Tools
Tools that indirectly facilitate migration or synchronization:
- AWS CLI
- S3 CLI
- AWS Application Discovery Service: plan to…
- Agentless Collector
- Agent-based Discovery
Decision Making
- < TB Scale
- Internet transfer
- AWS DataSync
- Storage Gateway
- TBs
- Snowball
- Direct Connect
- DataSync + Direct Connect
- PB Scale and Above
- Snowball Edge
- Snowmobile
- Use Case Scenarios
- db migration → DMS
- file server → DataSync/Storage Gateway
- application server → Application Migration Service
- sync → DataSync/DMS
