AWS Transfer Family support for the Applicability Statement (AS2) protocol has increased its default message size limit from 50 MB to 1 GB and throughput limit from 30 to 100 message transfers per second. You will find these increased limits reflected on the AWS Transfer Family page within the Service Quotas console. These increased limits enable you to reliably connect with trading partners that frequently transmit sizable batches of AS2 messages.
The increased message size and throughput limits for AS2 are available in all AWS Regions where the service is available. To learn more about the AS2 quotas and limitations, visit the documentation. To get started with Transfer Family’s AS2 capabilities, take the self-paced workshop or deploy the AS2 CloudFormation template.
