A media streaming company uses Google Cloud Storage (GCS) for storing petabytes of video content. They have a strict requirement that all content must be accessible within milliseconds globally for their users, but also need to minimize storage costs for infrequently accessed archival footage. What is the most cost-effective storage class combination for this scenario?
- AFrequently accessed content in Multi-Regional; infrequently accessed content in Coldline Storage.
- BAll data in Multi-Regional Storage.
- CAll data in Standard Storage.
- DFrequently accessed content in Multi-Regional; infrequently accessed content in Archive Storage.
Show answer & explanationAnswer & explanation
Correct answer: D. Frequently accessed content in Multi-Regional; infrequently accessed content in Archive Storage.
Multi-Regional Storage provides high availability and low latency for frequently accessed data, suitable for global streaming. Archive Storage is the most cost-effective for infrequently accessed data with relaxed retrieval times, making it ideal for archival footage.
Why the other options are wrong
- A. Coldline is cheaper than Standard but still more expensive than Archive Storage for true archival needs, and has higher retrieval costs/latency than Archive for very infrequent access.
- B. Multi-Regional is good for frequently accessed data but too expensive for archival.
- C. Standard Storage has higher costs than necessary for archival data and might not meet global millisecond access requirements as efficiently as Multi-Regional.
Google Cloud Storage Classes
Different storage classes in GCS offer varying levels of availability, latency, and cost, allowing optimization based on data access patterns.
- Standard: High availability, low latency, general purpose.
- Nearline: Lower cost for data accessed less than once a month.
- Coldline: Even lower cost for data accessed less than once a quarter.
- Archive: Lowest cost for data accessed less than once a year.
Memory trick: Access needs dictate the GCS class, balancing speed and price.
