Zorluk: Çok zorPlanning Cloud Storage Buckets and Storage Classes

An organization is designing a Cloud Storage lifecycle policy for financial audit archives. The data access pattern is strictly defined as follows: objects are actively accessed multiple times daily for the first 30 days; between 31 and 90 days, objects are queried only once per month during financial reconciliation; after 90 days, objects are strictly retained for compliance and accessed less than once a year for 7 years. To minimize total cost of ownership (TCO) while avoiding early deletion/transition fee penalties and high data retrieval charges, which storage class lifecycle strategy should be planned?

  1. Store objects initially in Standard storage, configure an Object Lifecycle Management rule to transition objects to Nearline storage after 30 days, and add a second rule to transition objects to Archive storage after 90 days.Cevap
  2. B
    Store objects initially in Standard storage, and configure an Object Lifecycle Management rule to transition objects directly to Archive storage after 30 days.
  3. C
    Store objects initially in Coldline storage, and configure an Object Lifecycle Management rule to transition objects to Archive storage after 90 days.
  4. D
    Store objects initially in Nearline storage, configure an Object Lifecycle Management rule to transition objects to Coldline storage after 15 days, and transition to Archive storage after 30 days.

Cevap

Store objects initially in Standard storage, configure an Object Lifecycle Management rule to transition objects to Nearline storage after 30 days, and add a second rule to transition objects to Archive storage after 90 days.
The correct strategy starts with Standard storage for the first 30 days to accommodate active daily access without retrieval fees. At 30 days, transitioning to Nearline storage matches the monthly access requirement and satisfies Nearline's 30-day minimum storage duration. At 90 days, transitioning to Archive storage provides the lowest cost for long-term compliance retention with access frequency under once per year.

Adım Adım Çözüm

1
Analyze the access pattern for the initial 30-day period.
Daily active access requires Standard storage to avoid data retrieval fees.
Standard storage has no minimum retention duration and zero retrieval fees per GB, making it optimal for active data.
2
Evaluate the 31-90 day window and transition requirements.
Transitioning to Nearline storage at day 30 satisfies the monthly reconciliation access frequency.
Nearline storage is designed for data accessed at most once a month, has a 30-day minimum storage duration (satisfied between day 30 and day 90), and has lower retrieval costs than Coldline or Archive.
3
Evaluate the long-term storage requirement after 90 days.
Transitioning to Archive storage at day 90 maximizes long-term cost savings.
Archive storage offers the lowest storage cost per GB for data accessed less than once a year, perfectly matching the 7-year regulatory retention requirement.
