Zorluk: KolayCost-Optimized Storage Tiering and Lifecycle Management

A media company runs a transcoding application that generates output files of approximately 22 MB each. These files are accessed frequently by downstream users for exactly 1010 days, after which they are deleted. The company wants to minimize its storage costs on Amazon S3. Which storage strategy is the most cost-effective for these output files?

  1. A
    Keep the files in Amazon S3 Standard and route all internal transcoding traffic to the S3 bucket through a NAT Gateway to optimize retrieval costs.
  2. B
    Transition the files to Amazon S3 Standard-Infrequent Access (Standard-IA) after 11 day, and delete them at day 1010.
  3. Keep the files in Amazon S3 Standard for the entire 1010 days, and then delete them using an S3 Lifecycle expiration rule.Cevap
  4. D
    Transition the files to Amazon S3 Glacier Flexible Retrieval immediately, and configure expedited retrievals for the 1010-day active window.

Cevap

Keep the files in Amazon S3 Standard for the entire 1010 days, and then delete them using an S3 Lifecycle expiration rule.
Keeping the files in Amazon S3 Standard for the entire duration and deleting them via lifecycle policies is the most cost-effective option. Amazon S3 Standard does not charge retrieval fees and has no minimum storage duration. Since the files are deleted after 1010 days, any transition to S3 Standard-IA or Glacier classes would trigger minimum storage charges (3030 days for Standard-IA, 9090 days for Glacier), resulting in higher costs.

Adım Adım Çözüm

1
Evaluate the data access pattern and retention period.
The files are accessed frequently for 1010 days and then deleted.
Understanding the lifecycle of the data determines which storage tiers can be used without penalties.
2
Analyze storage class constraints, specifically minimum storage duration.
Amazon S3 Standard has no minimum storage duration. Amazon S3 Standard-IA has a 3030-day minimum storage duration. Amazon S3 Glacier Flexible Retrieval has a 9090-day minimum storage duration.
Using Standard-IA or Glacier for data that is deleted after 1010 days will result in paying for unused storage (3030 days and 9090 days of billing, respectively).
3
Determine the most cost-effective option based on duration and access rules.
S3 Standard is the most cost-effective tier because it avoids early deletion charges for the 1010-day lifecycle.
Since the files are accessed frequently and deleted well before 3030 days, S3 Standard is cheaper than Standard-IA or Glacier classes.
