Resilience in AWS Transfer Family

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between Availability Zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures.

AWS Transfer Family supports up to 3 Availability Zones and is backed by an auto scaling, redundant fleet for your connection and transfer requests.

For all Transfer Family endpoints:

• Availability Zone-level redundancy is built into the service.

• There are redundant fleets for each AZ.

• This redundancy is provided automatically.

Note

For endpoints in a Virtual Private Cloud (VPC), it is possible to provide a single subnet. However, we recommend that you create endpoints in multiple availability zones within your VPC, to reduce the risk of service disruptions during Availability Zone outages.
