使用AWS SFTP时能否借助AWS Transfer Acceleration for S3的加速能力？

Absolutely! AWS Transfer Family (which supports SFTP, FTPS, and FTP protocols) works seamlessly with Amazon S3 Transfer Acceleration to boost file transfer speeds—especially handy for cross-region or long-distance transfers. Here's a straightforward breakdown of how to make this work and key details to keep in mind:

Step 1: Enable Transfer Acceleration on Your S3 Bucket #

First, turn on Transfer Acceleration for your target S3 bucket:

• Head to the S3 console, select your bucket, and navigate to the Properties tab.
• Scroll to the Transfer Acceleration section and toggle it on.
• Once enabled, you’ll get an accelerated endpoint URL in the format: <bucket-name>.s3-accelerate.amazonaws.com

Step 2: Configure AWS Transfer Family to Use the Accelerated Endpoint #

When setting up (or updating) your SFTP server, point it to the accelerated S3 endpoint instead of the default regional S3 endpoint:

• Console setup: When configuring the S3 storage location for your Transfer server or user home directory, expand the Advanced settings section. Under S3 endpoint, paste the accelerated URL from Step 1.
• CLI/API setup: Use the create-server or update-server commands, specifying the accelerated endpoint via the --s3-storage-options parameter. For example:

  aws transfer create-server \
    --identity-provider-type SERVICE_MANAGED \
    --endpoint-type PUBLIC \
    --s3-storage-options '{"Bucket": "your-target-bucket", "Endpoint": "your-target-bucket.s3-accelerate.amazonaws.com"}'
  

Key Notes to Remember #

• Performance: Transfer Acceleration routes your SFTP traffic through AWS’s global edge network, cutting down latency for transfers between distant locations.
• Cost: S3 Transfer Acceleration has additional data transfer fees, so be sure to review pricing details to confirm it fits your budget.
• Permissions: The IAM role linked to your Transfer Family server just needs standard S3 permissions (like s3:PutObject or s3:GetObject)—no extra permissions are required to use the accelerated endpoint.
