How to get data into the S3 Intelligent-Tiering storage class

 There are two main ways to get data into the S3 Intelligent-Tiering storage class:

1. Direct PUT operation:

   • When uploading an object to S3, you can specify the 
     INTELLIGENT_TIERING
      storage class in the 
     x-amz-storage-class
      header.
   • Example CLI command:

     aws s3 cp local_file.txt s3://my-bucket/my-object.txt --storage-class INTELLIGENT_TIERING

2. Lifecycle policy transition:

   • You can create a lifecycle policy to automatically transition objects from the S3 Standard or S3 Standard-IA storage classes to the S3 Intelligent-Tiering storage class.
   • This can be done using the AWS Management Console, AWS CLI, or AWS SDK.
   • Example lifecycle policy configuration:

     {
       "Rules": [
         {
           "Status": "Enabled",
           "Transitions": [
             {
               "StorageClass": "INTELLIGENT_TIERING",
               "TransitionInDays": 30
             }
           ]
         }
       ]
     }
