We are happy to announce that Amazon S3 is now available on the Engine Yard platform.
You can now easily setup AWS S3 cloud storage buckets for use with your Engine Yard application. Simply log into the Engine Yard console and select "Cloud Storage" from the "Tools" drop down. From here you can setup storage buckets and configure users and permissions for all of our supported AWS regions. All charges for usage of AWS S3 will be added to your invoice under the "AWS Other Services". For more information, please see the Knowledge Base document here.
