AWS S3 bucket naming conventions

Cloudinary support 3 main uses for customers that involve using S3 buckets which are customer-owned (external to Cloudinary's AWS infrastructure) and have no public access, i.e private S3 buckets:

1. Backup - backing up to your own private S3 bucket

2. Auto upload - uploading from an external S3 bucket

3. Primary storage - replace Cloudinary's storage servers with your own for storage purposes (This is a premium feature that requires a special setup. For more information, contact us). 

Below are the naming and region conventions to be used to support each option:

• Backup
  
  • V4 buckets (**)
  • {XXX}-{region} , for example : mybucket-eu-central-1
• Auto upload
• Same as backup
  
  
• Primary Storage
• {XXX}-{region}-cld , for example :mybucket-eu-central-1-cld

Note that Cloudinary supports all regions for all purposes including auto upload purposes.

In all cases, your private bucket name should be identical to the bucket name that is listed in the Cloudinary account and also include the region suffix.

It's possible to see the list of S3 regions in the link below:

(**)  The versions refer to the bucket signature authentication version. All AWS regions support the new version (4), and there are still some regions that also support the old version (2).
