A Cloud Engineer discovers that a daily log export process into a Cloud Storage bucket is incurring high operational costs. Inspection reveals an Object Lifecycle Management rule configured to transition objects to the Coldline storage class zero days after creation. However, an automated analytics pipeline reads these newly created log files multiple times daily during their first two weeks before access drops completely. Which action should the engineer take to resolve the issue and optimize costs?

  1. Modify the lifecycle rule to keep objects in Standard storage for 30 days before transitioning them to Coldline storage.Cevap
  2. B
    Change the bucket default storage class to Archive while leaving the immediate transition lifecycle rule active.
  3. C
    Migrate the daily export storage target from Cloud Storage to Cloud Bigtable and configure an age-based garbage collection policy.
  4. D
    Enable Uniform Bucket-Level Access on the Cloud Storage bucket to automatically negate retrieval fees for active objects.

Cevap

Modify the lifecycle rule to keep objects in Standard storage for 30 days before transitioning them to Coldline storage.
Cloud Storage Standard storage carries no retrieval fee, making it the most economical choice for data accessed repeatedly during the first two weeks. Delaying the transition to Coldline until after 30 days eliminates retrieval fee penalties while ensuring long-term storage savings once queries cease.

Adım Adım Çözüm

1
Analyze access patterns and storage class pricing mechanics.
Identified that logs are read frequently during the first two weeks after creation.
Coldline storage incurs retrieval costs per gigabyte read, making it unsuitable for frequently accessed data.
2
Evaluate Object Lifecycle Management lifecycle transition rules.
Transitioning immediately (day 0) to Coldline incurs heavy retrieval charges every time the analytics pipeline reads the new logs.
Standard storage has no retrieval fee, making it cheaper for short-term active reading.
3
Select the optimal lifecycle rule policy.
Keep objects in Standard storage while actively queried, then transition to Coldline after 30 days when access drops.
This aligns storage class tiering with actual access patterns to minimize total operational costs.
