Intro:

• Moving data between Amazon S3 storage classes is a common practice to optimize costs as data ages or access patterns change. 
• There are several ways to move objects between S3 storage classes:

Architecture diagram: 

1. Lifecycle Configuration Rules (Automatic)

twtech can define lifecycle policies to automatically transition objects between storage classes based on object age or creation date.

 Sample Lifecycle Transitions:

# yaml

Transition:

- Day 30 → S3 Standard-IA

- Day 90 → S3 Glacier Instant Retrieval

- Day 180 → S3 Glacier Deep Archive

 How to Set Up:

1. AWS Console: Go to S3 bucket > Management > Lifecycle rules.
2. AWS: CLI

# bash

aws s3api put-bucket-lifecycle-configuration --bucket twtech-s3bucket \

--lifecycle-configuration file://lifecycle.json

# Sample lifecycle.json:

#  json

{

  "Rules": [

    {

      "ID": "TransitionToGlacier",

      "Status": "Enabled",

      "Prefix": "",

      "Transitions": [

        {

          "Days": 30,

          "StorageClass": "STANDARD_IA"

        },

        {

          "Days": 90,

          "StorageClass": "GLACIER"

        }

      ],

      "NoncurrentVersionTransitions": [ ],

      "Expiration": {

        "Days": 365

      }

    }

  ]

}

 2. Manual Movement (One-time or Ad Hoc)

• twtech Uses this when it needs to manually move a specific object or batch of objects to a different class.

 AWS CLI:

# bash

aws s3 cp s3://twtech-s3bucket/twtech-object.txt s3://twtech-s3bucket-crr-replica/twtech-object.txt \

--storage-class GLACIER --metadata-directive REPLACE

 NB:

• S3 does not allow in-place class changes. twtech must copy and overwrite the object to change its storage class.

 3. Upload with Storage Class Specified

• twtech can specify the desired storage class at upload time.

 AWS: CLI

#  bash

aws s3 cp twtech-file.txt s3://twtech-s3bucket/ --storage-class STANDARD_IA

 Available Storage Classes for Transitions

Storage Class	Notes
STANDARD	Default
INTELLIGENT_TIERING	Auto-tiering based on access
STANDARD_IA	Infrequent Access
ONEZONE_IA	Lower-cost IA in one AZ
GLACIER_INSTANT_RETRIEVAL	Archive, fast access
GLACIER	Archive, flexible retrieval
DEEP_ARCHIVE	Cheapest, slowest access

 twtech Best Practices.

• Use Intelligent-Tiering for unpredictable access.
• Use Lifecycle rules for predictable aging data.
• Use tag-based policies to transition only selected objects.

Project: Hands-on

How twtech creates its s3-buckets then edit storage class life cycle rules to: Move or transition objects betweenstorage classes.

• twtech Creates a  bucket: twtech-s3-class-transitioning

• Assign name: twtech-s3-class-transition.

• Created in any region of choice: us-east-2(Ohio)

• Create bucket in any region of choice: us-east-2 (Ohio)

• Select object to Upload to the bucket: twtech-logo4

• Configure storage class for object to upload: twt-logo4.jpg

• Navigate to properties: To configure the choice of storage class desired for the object.
• Select the preferred storage class: standard storage class.

• Go to the bucket to access object: twtech-s3-class-transition
• The object indicates a storage class: Standard.

• twtech changes the storage class of its objects in the bucket by editing properties of the object: from standart to
• Select the  object to edit the properties of the storage class and click open: twt-logo4.jpg

• Navigate to the section:  storage class to edit.

• From standard to: One Zone-IA (meaning this object can only be stored in one zone only)

From:

To:

• Save changes:

• Return to the bucket and Verify that the storage class has actually been changed: from standard to One Zone-IA

Yes.

• twtech creates lifecycle rule to  move (transition) objects between search classes: by creating lifecyle rules.
• Go to:  bucket management tab.

• Create lifecycle rule: twtech-lifecycle-rule

• Create lifecycle rule: twtech-lifecycle-rule
