How do I right-size resources for AWS S3?

Right-sizing resources for AWS S3 involves optimizing storage classes, lifecycle policies, and access patterns to ensure efficient and cost-effective use of storage. By understanding your data's characteristics, you can choose the appropriate storage class and implement policies to transition data to lower-cost classes over time.

    // Example of setting up an S3 bucket lifecycle policy to transition 
    // objects to the Standard-IA storage class after 30 days.
    $bucket = 'my-bucket';
    $lifecyclePolicy = [
        'Rules' => [
            [
                'ID' => 'TransitionToIA',
                'Filter' => [
                    'Prefix' => '', // Applies to all objects
                ],
                'Status' => 'Enabled',
                'Transitions' => [
                    [
                        'Days' => 30,
                        'StorageClass' => 'STANDARD_IA',
                    ],
                ],
            ]
        ]
    ];

    $s3Client->putBucketLifecycleConfiguration([
        'Bucket' => $bucket,
        'LifecycleConfiguration' => $lifecyclePolicy,
    ]);
