AWS Transfer Family vs DataSync: Cost Structure
Charges Based on Usage
For AWS Transfer Family, users are billed in two primary ways:
- Based on the time each protocol (like SFTP, FTPS, FTP) is enabled on their server endpoint.
- For the amount of data both uploaded and downloaded.
On the other hand, AWS DataSync adopts a more straightforward pricing model. Users are charged solely based on the volume of data copied.
Additional Charges & Fees
AWS Transfer Family has additional charges that users might incur depending on their specific usage patterns. For instance, features like AS2 messages or workflows might come with extra costs.
In contrast, AWS DataSync emphasizes simplicity in its pricing. There are no hidden fees, no resources to manage, no upfront costs, and no minimum charge, ensuring users only pay for the data they transfer.
Upfront and Hidden Costs
While AWS Transfer Family doesn’t explicitly mention upfront or hidden costs, it’s essential to be aware of the various features and their associated charges, ensuring there are no surprises in the billing.
AWS DataSync stands out by explicitly stating its commitment to no upfront or hidden costs. Users can be confident that they won’t encounter unexpected charges, and they won’t need to manage any resources, further simplifying the cost structure.
AWS Transfer Family vs DataSync: Use Cases
Traditional File Transfer Workflows
AWS Transfer Family is specifically designed to cater to businesses that rely on traditional file transfer protocols. Whether it’s migrating existing file transfer workflows to the cloud or setting up a new system, Transfer Family’s support for SFTP, FTPS, and FTP makes it the preferred choice.
On the contrary, while AWS DataSync can handle data transfers, its primary design isn’t centered around replacing traditional file transfer workflows. Instead, it focuses on other use cases, as discussed below.
Winner: AWS Transfer Family
Large-Scale Data Migrations and Backups
AWS DataSync shines when it comes to migrating large datasets between on-premises storage and AWS storage services or even between AWS storage services. Its optimized protocol ensures high-speed data transfers, making large data migrations efficient and timely.
While AWS Transfer Family can handle data transfers to and from Amazon S3, its design and cost structure might not make it the most efficient choice for massive data migrations or frequent, large-scale backups.
Winner: AWS DataSync
Data Sharing and Collaboration
AWS Transfer Family is well-suited for scenarios where businesses need to share data with external partners or customers. Its support for widely-used protocols ensures compatibility and ease of access for various users, making data sharing and collaboration straightforward.
AWS DataSync, on the other hand, is more focused on the movement of data rather than sharing. Its primary use cases revolve around data migration and backup, rather than collaboration.
Winner: AWS Transfer Family
Conclusion
Choosing between AWS Transfer Family and AWS DataSync boils down to specific requirements. If traditional file transfer protocols are a necessity, Transfer Family is the way to go. However, for large-scale data migrations or backups, DataSync offers a more cost-effective and efficient solution. As always, understanding your data transfer patterns and needs will guide you to the right choice.
FAQ: AWS DataSync vs. Transfer Family
1. What is the difference between DataSync and S3 transfer acceleration?
AWS DataSync is a service designed to move large amounts of data online between on-premises storage and AWS services like Amazon S3, EFS, and FSx. It uses its own optimized protocol to accelerate transfers. On the other hand, S3 Transfer Acceleration is a specific feature of Amazon S3 that speeds up transferring files to and from S3 by using Amazon CloudFront’s globally distributed edge locations.
2. What is the difference between DataSync and storage gateway?
AWS DataSync focuses on online data transfers between on-premises storage and AWS services. In contrast, AWS Storage Gateway is a hybrid cloud storage service that connects an on-premises software appliance with cloud-based storage, providing seamless integration with on-premises IT environments and AWS storage infrastructure. It’s more about integrating and extending on-premises storage into the cloud.
3. What is the advantage of AWS DataSync?
AWS DataSync offers a fast, secure, and simple way to transfer large datasets between on-premises storage and AWS storage services. It automates many of the tasks related to data transfers, such as data validation and monitoring, ensuring efficient and error-free transfers. Its optimized protocol also ensures that data is transferred at high speeds, reducing the time required for data migrations or backups.
4. How does AWS DataSync ensure data integrity?
AWS DataSync uses a combination of checksums and in-transit encryption to ensure that data is transferred securely and without errors. After each transfer, DataSync automatically validates the data to ensure that the source and destination data are identical.
5. Can I use AWS Transfer Family for large-scale data migrations?
While AWS Transfer Family is designed for transferring files using traditional protocols, it’s not optimized for large-scale data migrations. For massive data transfers or migrations, AWS DataSync or AWS Snowball might be more suitable due to their optimized transfer mechanisms and scalability.
6. What is the advantage of AWS DataSync over AWS Transfer Family?
AWS DataSync is specifically designed for high-speed, large-scale data migrations and regular backups to AWS. It uses an optimized protocol to ensure rapid data transfers and offers automation features like data validation post-transfer. This makes it ideal for moving vast amounts of data between on-premises storage and AWS services.
7. What is the advantage of AWS Transfer Family over AWS DataSync?
AWS Transfer Family shines when it comes to supporting traditional file transfer protocols like SFTP, FTPS, and FTP. It’s designed for businesses that need to integrate existing file transfer workflows into the cloud or share data with partners using these familiar protocols. Its primary advantage is providing a seamless transition for organizations relying on traditional file transfer methods.
8. Should I use AWS DataSync or AWS Transfer Family for on-prem to AWS replication?
For large-scale data replication or migrations from on-premises to AWS, AWS DataSync is typically the recommended choice due to its optimized transfer protocol and automation features. However, if the replication involves traditional file transfer workflows using protocols like SFTP, FTPS, or FTP, then AWS Transfer Family might be more suitable. It’s essential to assess the specific requirements and data transfer patterns before making a decision.
