- In S3, data is stored as objects in buckets. A bucket is a logical container for storing data. S3 supports a single object of upto 5 terabytes in size.
- All objects in buckets can be organized using prefixes. Prefixes are the full path of the object's location that comes before the file name and upto the last '/' character of the file path.
- S3 has capability to add metatags to objects.
- S3 object tags which is a key/value pairs can be added to each objects. These object tags can be created, updated, and deleted all throught the object's life cycle.

- S3 supports batch operations by providing a solution called S3 Batch Operations. The S3 Batch Operations makes it possible for storing data of any scale, from thousands to billions of objects in a single request. Using S3 API request or the Amazon S3 Management Console, you can copy any number of objects from one bucket to another, modify existing access control, restore archieve objects from Amazon S3 Glacier, etc. S3 Batch Operations also supports running of Lambda functions for implementing custom business logic across objects.
