Uploading, downloading, and working with objects in Amazon S3 - Amazon Simple Storage Service

Uploading, downloading, and working with objects in Amazon S3

To store your data in Amazon S3, you work with resources known as buckets and objects. A bucket is a container for objects. An object is a file and any metadata that describes that file.

To store an object in Amazon S3, you create a bucket and then upload the object to a bucket. When the object is in the bucket, you can open it, download it, and copy it. When you no longer need an object or a bucket, you can clean up these resources.


For more information about using the Amazon S3 Express One Zone storage class with directory buckets, see What is S3 Express One Zone? and Directory buckets.


In the Amazon S3 console, when you choose Open or Download As for an object, these operations create presigned URLs. For the duration of five minutes, your object will be accessible to anyone who has access to these presigned URLs. For more information about presigned URLs, see Using presigned URLS.

With Amazon S3, you pay only for what you use. For more information about Amazon S3 features and pricing, see Amazon S3. If you are a new Amazon S3 customer, you can get started with Amazon S3 for free. For more information, see AWS Free Tier.
