    • QUOTE: … Avoiding cross-account object and bucket ownership is strongly advised. This is resolved by always performing S3 operations with an IAM role within the bucket owning account. Doing this ensures that the bucket owner and object owner are the same. This also helps simplify access by reducing the number of places where S3 permissions can live, which ultimately improves the security of your infrastructure.

    • QUOTE: Every object stored in Amazon S3 is contained in an bucket. Buckets partition the namespace of objects stored in Amazon S3 at the top level. Within a bucket, you can use any names for your objects, but bucket names must be unique across all of Amazon S3.

      Buckets are similar to Internet domain names. Just as Amazon is the only owner of the domain name Amazon.com, only one person or organization can own a bucket within Amazon S3. Once you create a uniquely named bucket in Amazon S3, you can organize and name the objects within the bucket in any way you like and the bucket will remain yours for as long as you like and as long as you have the Amazon S3 account.

      The similarities between buckets and domain names is not a coincidence — there is a direct mapping between Amazon S3 buckets and subdomains of s3.amazonaws.com. Objects stored in Amazon S3 are addressable using the REST API under the domain bucketname.s3.amazonaws.com. For example, if the object homepage.html is stored in the Amazon S3 bucket mybucket its address would be http://mybucket.s3.amazonaws.com/homepage.html. For more information, see Virtual Hosting of Buckets.

      To determine whether a bucket name exists using REST, use HEAD, specify the name of the bucket, and set max-keys to 0. To determine whether a bucket name exists using SOAP, use ListBucket and set MaxKeys to 0. A NoSuchBucket response indicates that the bucket is available, a AccessDenied response indicates that someone else owns the bucket, and a Success response indicates that you own the bucket or have permission to access it.
