Question

Explain the S3 Lifecycle Policies.

Answer 1

S3 Lifecycle Policies allow you to manage your objects so that they are stored cost-effectively throughout their lifecycle. You can define rules to:

• Transition objects to another storage class (e.g., from S3 Standard to S3 Standard-IA).
• Expire objects by deleting them after a specified period.
• Archive older versions of objects to Glacier.
• Remove incomplete multipart uploads.

Example of a lifecycle policy to transition objects to S3 Glacier after 30 days and delete after 365 days:

{
  "Rules": [
    {
      "ID": "TransitionToGlacierAndExpire",
      "Prefix": "",
      "Status": "Enabled",
      "Transitions": [
        {
          "Days": 30,
          "StorageClass": "GLACIER"
        }
      ],
      "Expiration": {
        "Days": 365
      }
    }
  ]
}
