    fmt.Println("File uploaded to S3 with Standard-IA storage class and archived to S3 Glacier")
}

STANDARD: Standard storage class for frequently accessed data.
STANDARD_IA: Standard-Infrequent Access storage class for infrequently accessed data.
ONEZONE_IA: One Zone-Infrequent Access storage class for infrequently accessed data that can be recreated.
INTELLIGENT_TIERING: Intelligent Tiering storage class for data with unknown or changing access patterns.
GLACIER: Glacier storage class for long-term data archival.
DEEP_ARCHIVE: Deep Archive storage class for long-term data archival with the lowest cost.
