How Does Amazon S3 Work?
Amazon S3 uses a simple structure to store and organize your data:
Buckets
A bucket is like a container where you store your files (also called objects).
Each bucket has a unique name across all of AWS.
You can create multiple buckets for different projects or purposes.
Objects
The actual files (like documents, photos, or videos) you store in Amazon S3 are called objects.
Each object has a unique key (name) within the bucket.
Folders
S3 doesn’t have actual folders, but you can organize your files in a folder-like structure using prefixes.
For example,
mybucket/project1/file1.jpglooks like a file stored in a folder namedproject1.
Key Differences Between S3 Bucket and Object
| Aspect | S3 Bucket | S3 Object |
| Definition | A container that stores objects. | The actual data (file) stored in a bucket. |
| Purpose | Organizes and groups objects. | Represents the individual files within a bucket. |
| Structure | Top-level container in S3. | File stored with data, key, and metadata. |
| Uniqueness | Must have a globally unique name. | Identified by a unique key (name) within a bucket. |
| Size Limit | A bucket has no limit on size. | Objects can be up to 5 TB in size. |
| Permissions | Access control can apply to the entire bucket. | Permissions can be applied at the individual object level. |
| Examples | my-first-bucket | my-first-bucket/photo.jpg |
