Google Cloud Digital LeaderInfrastructure modernization with Google CloudEasy
A global media company needs a highly scalable and durable storage solution for their vast archive of raw video footage. This footage is accessed infrequently, perhaps once a year for specific projects, but when it is needed, it must be retrieved within minutes. Cost optimization for long-term storage is a primary concern. Which Google Cloud Storage class should they choose?
- AArchive storage
- BColdline storage
- CNearline storage
- DStandard storage
Show answer & explanationAnswer & explanation
Correct answer: B. Coldline storage
Coldline storage is designed for data accessed less than once a month, offering lower storage costs than Nearline while still supporting retrieval in minutes. This aligns with the 'accessed infrequently, retrieved within minutes' requirement.
Why the other options are wrong
- A. Archive storage is for data accessed less than once a year, with retrieval times typically in hours, which does not meet the 'within minutes' requirement.
- C. Nearline storage is for data accessed less than once a month (e.g., once a quarter), but Coldline is more cost-effective for even less frequent access while still providing fast retrieval.
- D. Standard storage is for frequently accessed data, making it too expensive for archival footage.
Google Cloud Coldline Storage
A low-cost, highly durable storage class for data accessed infrequently (e.g., once a quarter or less) that requires retrieval in minutes.
- Lower storage cost than Nearline, higher than Archive
- Retrieval latency in minutes
- Minimum storage duration of 90 days
Memory trick: Storage classes: Like a library, how often you check it out determines its shelf.
