A global media company uses Google Cloud Storage (GCS) for storing petabytes of video content. They have a mix of content: frequently accessed new releases, content for active production workflows, and a vast archive of older, rarely accessed footage that must be retained for compliance for over 10 years. The company wants to minimize storage costs while ensuring appropriate access performance for each content type. Which GCS storage class strategy should they implement?
- AUse only the Archive storage class for all content to achieve the lowest possible storage costs.
- BUtilize Object Lifecycle Management (OLM) rules to transition data from Standard to Nearline, then to Coldline, and finally to Archive storage classes based on access patterns.
- CStore all actively used content in Standard, all archival content in Archive, and manually manage intermediate content.
- DStore all content in the Standard storage class and manually move older content to Coldline.
Show answer & explanationAnswer & explanation
Correct answer: B. Utilize Object Lifecycle Management (OLM) rules to transition data from Standard to Nearline, then to Coldline, and finally to Archive storage classes based on access patterns.
Object Lifecycle Management (OLM) rules automate the transition of objects between storage classes based on predefined conditions (e.g., age). This allows the company to automatically move data from more expensive, frequently accessed classes (Standard) to progressively cheaper, less frequently accessed classes (Nearline, Coldline, Archive) as it ages, optimizing costs while maintaining accessibility.
Why the other options are wrong
- A. Storing all content in Archive would result in high retrieval costs and latency for frequently accessed new releases and actively used production content, failing to meet performance requirements.
- C. Manually managing intermediate content is inefficient for petabytes of data and doesn't fully leverage the automatic cost savings of tiered storage classes.
- D. Manually moving petabytes of data is operationally intensive and prone to errors, failing to minimize operational overhead.
Google Cloud Storage Classes
Google Cloud Storage (GCS) offers different storage classes (Standard, Nearline, Coldline, Archive) to optimize costs and access performance based on data access frequency and retention needs.
- Standard: High performance, frequently accessed data.
- Nearline: Less frequent access (monthly), lower cost.
- Coldline: Infrequent access (quarterly), even lower cost.
- Archive: Very infrequent access (yearly or more), lowest cost, highest retrieval latency/cost.
