Using S3 Intelligent-Tiering

You can use the S3 Intelligent-Tiering storage class to automatically optimize storage costs. S3 Intelligent-Tiering delivers automatic cost savings by moving data on a granular object level between access tiers when access patterns change. For data that can be accessed asynchronously, you can choose to enable automatic archiving within the S3 Intelligent-Tiering storage class using the AWS Management Console, AWS CLI, or Amazon S3 API.

Moving data to S3 Intelligent-Tiering

There are two ways to move data into S3 Intelligent-Tiering. You can upload objects directly into S3 Intelligent-Tiering from the console or programmatically using a PUT operation. For more information, see Setting the storage class of an object. You can also configure S3 Lifecycle configurations to transition objects from S3 Standard or S3 Standard-Infrequent Access to S3 Intelligent-Tiering.

Uploading data to S3 Intelligent-Tiering using Direct PUT

When you upload an object to the S3 Intelligent-Tiering storage class using the PUT API operation, you specify S3 Intelligent-Tiering in the x-amz-storage-class request header.

The following request stores the image, my-image.jpg, in the myBucket bucket. The request uses the x-amz-storage-class header to request that the object is stored using the S3 Intelligent-Tiering storage class.

PUT /my-image.jpg HTTP/1.1
Host: myBucket.s3.<Region>.amazonaws.com (http://amazonaws.com/)
Date: Wed, 1 Sep 2021 17:50:00 GMT
Authorization: authorization string
Content-Type: image/jpeg
Content-Length: 11434
Expect: 100-continue
x-amz-storage-class: INTELLIGENT_TIERING 

Transitioning data to S3 Intelligent-Tiering from S3 Standard or S3 Standard-Infrequent Access using S3 Lifecycle

You can add rules to an S3 Lifecycle configuration to tell Amazon S3 to transition objects from one storage class to another. For information on supported transitions and related constraints, see Transitioning objects using S3 Lifecycle.

You can specify S3 Lifecycle configurations at the bucket or prefix level. In this S3 Lifecycle configuration rule, the filter specifies a key prefix (documents/). Therefore, the rule applies to objects with key name prefix documents/, such as documents/doc1.txt and documents/doc2.txt. The rule specifies a Transition action directing Amazon S3 to transition objects to the S3 Intelligent-Tiering storage class 0 days after creation. In this case, objects are eligible for transition to S3 Intelligent-Tiering at midnight UTC following creation.

<LifecycleConfiguration>
  <Rule>
    <ID>ExampleRule</ID>
    <Filter>
       <Prefix>documents/</Prefix>
    </Filter>
    <Status>Enabled</Status>
    <Transition>
      <Days>0</Days>
      <StorageClass>INTELLIGENT_TIERING</StorageClass>
    </Transition>
 </Rule>
</LifecycleConfiguration>

A versioning-enabled bucket maintains one current object version, and zero or more noncurrent object versions. You can define separate Lifecycle rules for current and noncurrent object versions.

For more information, see Lifecycle configuration elements.

Enabling S3 Intelligent-Tiering Archive Access and Deep Archive Access tiers

To get the lowest storage cost on data that can be accessed in minutes to hours, you can activate one or both of the archive access tiers by creating a bucket, prefix, or object tag level configuration using the AWS Management Console, AWS CLI, or Amazon S3 API.
