Snow Family (Offline Data Transfer)

  • Snowcone: Small device (~8 TB) → data transfer to S3/EC2.

  • Snowball Edge: Larger device (~20–80 TB), with compute/storage options.

  • Snowmobile: Truck-sized (up to 100 PB) for massive data migration.

FSx (Managed File Systems)

  • FSx for Windows Server:

    • Supports AD integration, SQL Server, SMB protocol.

    • ❌ No NFS.

    • ✅ Multi-AZ.

  • FSx for NetApp ONTAP:

    • Supports SMB, NFS, and S3 APIs.

  • FSx for Lustre:

    • Optimized for HPC.

    • ❌ No NFS, no AD, no Multi-AZ.

  • Not intended for migration, more for running workloads.

Storage Basics

  • RAID 0: Performance (striping).

  • RAID 1: Redundancy (mirroring).

Hybrid Storage & Migration

  • Storage Gateway: Connects on-prem storage to AWS.

    • Modes: File Gateway, Volume Gateway, Tape Gateway.

    • Cached mode (frequently used data cached locally).

    • Stored mode (entire dataset kept locally).

  • DataSync: Automates data transfer from on-prem → AWS.

  • Migration Service (DMS): Continuous replication for apps or databases (lift & shift).

  • AWS Backup: Centralized backup for multiple services (Aurora, EFS, DynamoDB, RDS, etc.).

⚡ In short:

  • Snow Family = physical appliances for bulk offline migration (from TB → PB scale).

  • FSx = managed file systems tailored for Windows, NetApp, HPC.

  • Storage Gateway / DataSync / DMS = hybrid + online migration tools.

  • AWS Backup = unified backup/restore across multiple AWS services.
