Vercel has added Amazon S3 storage provisioning to its Marketplace. The integration creates resources from the project dashboard and supplies connection settings automatically. Authentication uses short-lived credentials through OpenID Connect, so the application can access storage without storing permanent AWS access keys. The announcement includes an authenticated upload example.
An existing AWS account can be linked, but this integration supports only new buckets created through Vercel. That makes it a setup path for new storage resources, with deeper configuration still available in AWS.
