• Objects are essentially files
• Object keys are filenames
• An Access Key is essentially a username used for access to the S3 storage
• A Secret Key is essentially a password for a given access key = username
• Prefixes are folders
• A regionis conceptually a fileserver although in practice it consists of multiple servers linked together
