# Framework for secure, scalable, and trackable data transfer for Amazon Simple Storage Service (Amazon S3) objects and Amazon Elastic Container Registry (Amazon ECR) images
Guidance overview

Publication date: *December 2021 ([last update](revisions.md): November 2024)*

 The Data Transfer Hub Guidance provides secure, scalable, and trackable data transfer for Amazon Simple Storage Service (Amazon S3) objects and Amazon Elastic Container Registry (Amazon ECR) images. This data transfer helps you easily create and manage different types (Amazon S3 object and Amazon ECR image) of transfer tasks between AWS [partitions](https://docs.aws.amazon.com/whitepapers/latest/aws-fault-isolation-boundaries/partitions.html) (for example, aws, aws-cn, aws-us-gov), and from other cloud providers to AWS at your own discretion. 

If you have enabled the Direct Connect service in a specific AWS Region and a specific AWS China Region and have purchased a compliant cross-border dedicated line provided by a qualified operator to connect the AWS Region and their own VPC in the AWS China Region, you can use Data Transfer Hub's console to create a data transfer task and choose to use a dedicated line for data transfer at your own discretion.

 This implementation guide describes an overview of the Data Transfer Hub Guidance, its reference architecture and components, considerations for planning the deployment, and configuration steps for deploying Data Transfer Hub in the AWS Cloud. It also includes some tutorials with prescriptive guidance for using Data Transfer Hub.

 This guide is intended for IT architects, developers, DevOps, data analysts, and marketing technology professionals who have practical experience architecting in the AWS Cloud. 

You will be responsible for your compliance with all applicable laws in respect of your data transfer tasks.

# Features and benefits
Features and benefits

Depending on the availability of your network environment, the Guidance supports the following key features: 
+  **Inter-Partition and Cross-Cloud data transfer** - to promote seamless transfer capabilities in one place
+  **Auto scaling** - to allow rapid response to changes in file transfer traffic 
+  **High performance of large file transfer (1TB)** - to leverage the strengths of clustering, parallel large file slicing, and automatic retries to robust file transfer 
+ **Monitoring** - to track data flow, diagnose issues, and ensure the overall health of the data transfer processes
+  **Out-of-the-box deployment** 

**Note**  
If you want to transfer Amazon S3 objects between AWS Regions, we recommend that you use [Cross-Region Replication](https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication.html#crr-scenario). If you want to transfer Amazon S3 objects within the same AWS Region, we recommend using [Same-Region Replication.](https://docs.aws.amazon.com/AmazonS3/latest/userguide/replication.html#srr-scenario) 

For data transfer between AWS China Region and AWS Region, you will be responsible for your compliance with all applicable laws and regulations on cross-border data transfer (including purchasing compliant cross-border dedicated lines provided by qualified operators for data transfer, performing necessary government approval or filing), and shall initiate data transfer at your own discretion. AWS does not assist you with this data transfer.

# Use cases
Use cases

 Today, the China market is one of biggest markets in the world. Many international companies are seeking their success in China, as well as a number of Chinese companies are expanding their businesses globally. One of most important steps of in the business is moving their data. 

S3 Cross-Region Replication and ECR Cross-Region Replication are popular but customers cannot use them to replicate data into China Regions. With the launch of Data Transfer Hub Guidance, customers can now create S3 and ECR data transfer tasks between AWS Regions and AWS China Regions in a web portal. Moreover, it supports replicating data from other cloud providers to AWS. 

Depending on the availability of your network environment, Data Transfer Hub supports the following use cases: 
+ Copy Amazon S3 objects between AWS Regions and AWS China Regions. 
+ Copy data from other cloud providers’ object storage services to Amazon S3. 
+ Transfer Amazon ECR images between AWS Regions and AWS China Regions. 
+ Transfer Dockers image from public docker registry (for example, Docker Hub, Google gcr.io, Red Hat Quay.io) to Amazon ECR.
