# Prerequisites
<a name="setting-up"></a>

The following sections describe the prerequisites required to use the AWS Transfer Family service. At a minimum, you need to create an Amazon Simple Storage Service (Amazon S3) bucket and provide access to that bucket through an AWS Identity and Access Management (IAM) role. Your role also needs to establish a trust relationship. This trust relationship allows Transfer Family to assume the IAM role to access your bucket so that it can service your users' file transfer requests.

For information about IPv6 support for AWS Transfer Family servers, see [IPv6 support for Transfer Family servers](ipv6-support.md) in the Managing servers chapter.

## Supported AWS Regions, endpoints and quotas for Transfer Family servers
<a name="regions"></a>

To connect programmatically to an AWS service, you use an endpoint. For example, the endpoint for customers in US East (Ohio) region (`us-east-2`), is `transfer.us-east-2.amazonaws.com`. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. In this guide, you can find quotas in [AS2 quotas](create-b2b-server.md#as2-quotas) and [Quotas for SFTP connectors](scale-and-limits-sftp-connector.md#limits-sftp-connector).

For more information about supported AWS Regions, endpoints, and service quotas, see [AWS Transfer Family endpoints and quotas](https://docs.aws.amazon.com//general/latest/gr/transfer-service.html) in the *Amazon Web Services General Reference*.

For Transfer Family web apps, the supported regions are listed in [AWS Regions for Transfer Family web apps](web-app.md#webapp-regions). For quotas that pertain to Transfer Family web apps, see [Web app quotas](webapp-end-users.md#end-user-quotas).
