AWS Transfer Family is Amazon's managed file transfer service that supports SFTP, FTPS, FTP, and AS2 protocols backed by S3 or EFS storage. It's a solid product for enterprises already deep in the AWS ecosystem, but for many teams it's overkill — expensive, complex to configure, and loaded with features they'll never use.
If you need a straightforward SFTP endpoint for file exchange and don't want to wrestle with IAM roles, VPC configurations, and per-hour billing, there are better options. This guide breaks down the differences and helps you decide whether AWS Transfer Family or a simpler alternative like SFTPHub is the right fit.
What is AWS Transfer Family?
AWS Transfer Family is a fully managed AWS service that lets you transfer files over SFTP, FTPS, FTP, and AS2 directly into and out of Amazon S3 or Amazon EFS. It was launched in 2018 as "AWS Transfer for SFTP" and has since expanded to support additional protocols.
Key characteristics of AWS Transfer Family:
- Multi-protocol support — SFTP, FTPS, FTP, and AS2 on a single endpoint.
- AWS-native storage — Files land directly in S3 buckets or EFS file systems.
- IAM and identity provider integration — Supports AWS IAM, custom identity providers via API Gateway, or AWS Directory Service.
- VPC endpoint support — Can be deployed inside a VPC for private connectivity.
- CloudWatch and CloudTrail — Logging and audit trail integration.
For enterprises that need deep AWS integration, multi-protocol support, and custom identity providers, Transfer Family is a reasonable choice. But that power comes at a cost — both in dollars and complexity.
The Problem with AWS Transfer Family
Despite being "managed," AWS Transfer Family still requires significant AWS expertise and carries costs that surprise many teams:
1. It's Expensive
AWS Transfer Family charges $0.30 per hour per protocol for each server endpoint. That's roughly $216/month just to keep a single SFTP endpoint running — before you transfer a single byte. Add data transfer fees ($0.04/GB), S3 storage costs, and CloudWatch logging, and a basic setup can easily run $250–$400+/month.
Example: A single SFTP endpoint with 100 GB of storage and 150 GB of monthly transfers costs approximately $280/month with AWS Transfer Family. The same workload on SFTPHub costs $45/month on the Growth plan.
2. It's Complex to Set Up
Setting up an AWS Transfer Family endpoint requires configuring:
- S3 bucket with correct bucket policies and access points
- IAM roles and policies for the Transfer Family service
- Per-user IAM roles scoping S3 access (home directory mappings)
- Optional VPC endpoint for private connectivity
- Optional custom identity provider via API Gateway + Lambda
- CloudWatch log groups and metric alarms
- Route 53 DNS records for custom hostnames
This can take an experienced AWS engineer hours or days to configure correctly, and even longer to debug when something goes wrong. Compare this to a managed SFTP provider where you create an endpoint through a web dashboard in seconds.
3. You Still Manage Users Manually
AWS Transfer Family doesn't include a user management dashboard. Managing SFTP users means writing IAM policies, scoping S3 access per user, and potentially building a custom identity provider with Lambda. Adding or removing a user isn't a one-click operation — it's infrastructure work.
4. You're Locked into AWS
Transfer Family stores files in S3 or EFS. Your identity provider is IAM or a custom Lambda. Your logging is CloudWatch. Every piece of the stack ties you deeper into AWS, making it harder and more expensive to move later.
AWS Transfer Family vs SFTPHub
Here's a side-by-side comparison of AWS Transfer Family and SFTPHub:
| Feature | AWS Transfer Family | SFTPHub |
|---|---|---|
| Starting price | ~$216/mo (endpoint only) | $7/mo (storage included) |
| Per-GB transfer fees | $0.04/GB | None |
| Storage included | No (S3 billed separately) | Yes (5 GB – 1 TB) |
| Setup time | Hours to days | Under 2 minutes |
| AWS expertise required | Yes (IAM, S3, VPC, etc.) | No |
| User management | IAM policies or custom Lambda | Web dashboard |
| SSH key authentication | Yes | Yes |
| Password authentication | Custom Lambda required | Built in |
| Storage backend | S3 or EFS | S3 |
| Multi-protocol (FTP, FTPS, AS2) | Yes | SFTP only |
| Custom identity providers | Yes (Lambda + API Gateway) | No |
| Billing model | Per-hour + per-GB + S3 costs | Flat monthly rate |
Pricing Breakdown: AWS Transfer Family vs SFTPHub
The cost difference is significant, especially for small to mid-sized workloads. Here's what a typical month looks like:
| Workload | AWS Transfer Family | SFTPHub |
|---|---|---|
| 1 endpoint, 5 GB storage, 10 GB/mo transfer | ~$217/mo | $7/mo (Micro) |
| 1 endpoint, 100 GB storage, 150 GB/mo transfer | ~$228/mo | $45/mo (Growth) |
| 1 endpoint, 1 TB storage, 1 TB/mo transfer | ~$262/mo | $199/mo (Business) |
AWS Transfer Family pricing doesn't include S3 storage costs, CloudWatch logging, or data transfer out of AWS. The actual bill is often higher than the estimates above. SFTPHub pricing is all-inclusive — storage, transfers, and user management are included in every plan.
Bottom line: For most SFTP workloads, SFTPHub costs 80–95% less than AWS Transfer Family. See our pricing →
When to Use AWS Transfer Family
AWS Transfer Family is a good choice if:
- You need multi-protocol support (FTP, FTPS, AS2) alongside SFTP.
- You require custom identity providers that integrate with your existing auth system via Lambda.
- Your workflow depends on files landing directly in a specific S3 bucket for downstream AWS services (Lambda triggers, Step Functions, etc.).
- You have strict compliance requirements that mandate everything runs within your own AWS account and VPC.
- Cost is not a primary concern and you have AWS engineering capacity to manage the setup.
When to Choose an Alternative
An AWS Transfer Family alternative like SFTPHub is the better fit when:
- You just need SFTP — You don't need FTP, FTPS, or AS2. SFTP is the most secure option and the only protocol most teams actually use.
- You want simple user management — Create and manage SFTP users through a web dashboard with SSH key or password auth. No IAM policies, no Lambda functions.
- You want predictable costs — A flat monthly fee with storage included is easier to budget than per-hour + per-GB + S3 + CloudWatch pricing.
- You don't have AWS expertise — Setting up Transfer Family requires deep AWS knowledge. SFTPHub requires none.
- You need to get started quickly — Create an SFTP endpoint and start transferring files in under two minutes, not hours or days.
- Your team is small — Startups, small businesses, and agencies that need SFTP without the overhead of AWS infrastructure management.
How to Migrate from AWS Transfer Family
Since SFTP is a standard protocol, migrating from AWS Transfer Family is straightforward:
- Sign up for SFTPHub — Choose a plan that matches your storage needs.
- Create an SFTP instance — Provision your endpoint through the SFTPHub dashboard.
- Recreate your SFTP users — Add users with the same credentials (password or SSH key). SFTPHub supports all major key types.
- Migrate your files — Connect to your new endpoint and transfer your files from S3.
- Update your clients — Point your SFTP clients, scripts, and integrations to the new hostname and port.
- Decommission Transfer Family — Delete the AWS Transfer Family server, IAM roles, and associated resources to stop incurring charges.
The entire migration can be completed in an afternoon. No code changes are needed on the client side — just update the connection settings.
