What would you name your first bucket to ensure it's unique?
The files you store inside buckets are called objects. An object is made up of the file itself and metadata that describes the file. You can store virtually any type of file as an object in S3, from photos and videos to backups and log files.

Every object in a bucket has a unique identifier called a key, which is simply the object's name. For example, if you upload photo.jpg into a bucket named my-trip-pics, the key for that object is photo.jpg.
This simple bucket/key structure makes it easy to organize and retrieve your files.
