An advertising technology platform generates temporary campaign performance report files that average $45\text{ MB}$ in size. These reports are queried frequently by analytics tools for exactly $10\text{ days}$ after creation, after which they are no longer needed and must be deleted. A solutions architect needs to design a cost-optimized storage strategy for these files. Which strategy will meet these requirements at the lowest cost?

A
Transition the files to Amazon S3 Standard-Infrequent Access (S3 Standard-IA) after $1\text{ day}$ , and use an S3 Lifecycle policy to delete the files after $10\text{ days}$ .
B
Store the files in Amazon S3 Intelligent-Tiering and use an S3 Lifecycle policy to delete the files after $10\text{ days}$ .
Store the files in Amazon S3 Standard and use an S3 Lifecycle policy to delete the objects after $10\text{ days}$ .Cevap
D
Transition the files to Amazon S3 Glacier Flexible Retrieval after $1\text{ day}$ , and use an S3 Lifecycle policy to delete the files after $10\text{ days}$ .

Cevap

Store the files in Amazon S3 Standard and use an S3 Lifecycle policy to delete the objects after

10\text{ days}

The correct option is to store the files in Amazon S3 Standard and delete them after

10\text{ days}

using an S3 Lifecycle policy. Since the files are deleted after

10\text{ days}

, they do not meet the minimum storage duration requirements of S3 Standard-IA (

30\text{ days}

) or S3 Glacier Flexible Retrieval (

90\text{ days}

). Deleting them early from these tiers results in paying for the remaining storage duration as a penalty, making them more expensive than S3 Standard. Amazon S3 Intelligent-Tiering is also not cost-effective because it incurs a monitoring fee per object and the files are deleted before they can transition to lower-cost tiers.

Adım Adım Çözüm

Analyze the retention requirement of the files.

The files are only kept for

10\text{ days}

before being deleted.

Determines the total duration that storage charges will apply.

Evaluate the minimum storage duration rules of Amazon S3 storage classes.

S3 Standard-IA has a minimum of

30\text{ days}

, and S3 Glacier Flexible Retrieval has a minimum of

90\text{ days}

Helps identify if any storage classes will charge a penalty for early deletion.

Determine the most cost-effective storage class with no early deletion penalties.

S3 Standard has no minimum storage duration or deletion penalties, making it the most cost-effective option for files stored for only

10\text{ days}

Ensures the selected option achieves the lowest overall cost.
