s3 classes

You set the storage classes on the objects stored within S3 buckets, not during the S3 bucket creation. You can set S3 objects storage class manually or you can also automate the S3 storage class change using Intelligent Tiering (for putting S3 objects into Glacier/Glacier Deep Archive) or using Lifecycle rules (All storage classes)

To do it manually:
1. Create the S3 bucket, and configure it as you would like.

2. Upload an object into S3, such as a file, image, etc.

3. Select the object you just uploaded, and click on the "Actions" drop-down menu, and select "Edit Storage Class"
