Amazon S3 General Purpose Buckets: Read the Whole Object Key
An object inventory is more precise than a folder-shaped screenshot. This paper exercise uses fictional object keys in an Amazon S3 general purpose bucket. Keeping that bucket type explicit matters because S3 also has directory buckets with different directory semantics.
Write complete fictional identifiers
Use one invented general purpose bucket and two keys: practice/notes.txt and practice/archive/notes.txt. Keep the bucket name and the complete key in separate worksheet columns. The equal final filename does not make these the same object; the prefixes are part of their identifiers.
Separate a prefix from a filesystem directory
General purpose buckets have a flat object namespace. Prefixes and delimiters let the console present a useful hierarchy for browsing. A prefix is a beginning substring of a key, while a delimiter can group listing results. Preserve that distinction when converting a console observation into an API request or inventory entry.
Check the exact key string
Compare Practice/notes.txt with practice/notes.txt. Key names are case sensitive, so those strings identify different objects in this fixture. Record the value you actually used rather than normalizing its case or keeping only notes.txt. A naming mismatch is a different question from an access-permission failure.
Recognize a console folder marker
Creating a folder through the console in a general purpose bucket creates a zero-byte object whose key ends with a slash. The marker supports the folder presentation; it is not the contents of all objects sharing the prefix. Distinguish that marker from a normal document object when reviewing an inventory.
Keep the worksheet bounded
- State that the exercise uses a general purpose bucket.
- Record the complete key, including prefix, case and delimiters.
- Distinguish marker objects from the fictional content objects.
- Check bucket-type-specific documentation before extending the model.
Preserve the identifier before troubleshooting
No bucket creation, upload, deletion or permissions change is needed for this paper lab. The useful habit is to retain the full identifier before drawing a conclusion from a folder view. Apply that habit alongside the actual service and bucket-type rules in later authorized cloud practice.
