Tổng quan

AWS cung cấp nhiều công cụ migration tùy theo loại workload: database (DMS/SCT), data transfer (Snow/DataSync/Transfer Family), server (MGN). Chọn đúng tool dựa trên kích thước data, bandwidth, và loại workload.

AWS DMS & SCT

  • DMS (Database Migration Service): migrate database với minimal downtime.
  • Homogeneous: same engine (MySQL → MySQL). Không cần SCT.
  • Heterogeneous: khác engine (Oracle → PostgreSQL). Cần SCT convert schema trước.
  • CDC (Change Data Capture): continuous replication sau initial load.
  • DMS Serverless: auto-scale capacity.
  • Targets: RDS, Aurora, Redshift, DynamoDB, S3, OpenSearch.

Snow Family

  • Snowcone: 8-14 TB, nhỏ gọn, edge computing + DataSync agent.
  • Snowball Edge Storage Optimized: 80 TB, có compute (EC2, Lambda).
  • Snowball Edge Compute Optimized: 42 TB + GPU, cho ML/video ở edge.
  • Snowmobile: container truck, tới 100 PB. Cho exabyte-scale.
  • Quy trình: order → ship → load data → ship back → upload S3.
  • OpsHub: GUI quản lý Snow devices.

DataSync, MGN & Transfer Family

  • DataSync: online transfer, agent on-prem, NFS/SMB/HDFS/S3/EFS/FSx.
  • DataSync: bandwidth throttling, scheduling, integrity verification.
  • MGN (Application Migration Service): lift-and-shift, continuous replication → cutover.
  • MGN thay thế SMS (Server Migration Service) cũ.
  • Transfer Family: managed SFTP/FTPS/FTP/AS2 → S3 hoặc EFS.
  • Storage Gateway: hybrid storage (File/Volume/Tape) với local cache.
Tip
Chọn theo bandwidth: Internet nhanh → DataSync. Bandwidth hẹp + data lớn → Snowball. Database → DMS. Server → MGN.
