A cloud administrator is tasked with implementing a cost-effective storage solution for infrequently accessed log files that must be retained for compliance purposes for seven years. Retrieval times can be several hours, and data access patterns are unpredictable. Which storage tier is most appropriate for this use case?
- AStandard Object Storage
- BInfrequent Access Object Storage
- CBlock Storage
- DArchive Object Storage
Show answer & explanationAnswer & explanation
Correct answer: D. Archive Object Storage
Archive object storage tiers are designed for long-term retention of infrequently accessed data where retrieval times of several hours are acceptable. They offer the lowest storage costs, making them ideal for compliance archives.
Why the other options are wrong
- A. Standard object storage is for frequently accessed data and would be too expensive for infrequently accessed, long-term logs.
- B. Infrequent access object storage is for data accessed less frequently but still requires quick retrieval (minutes), which is not explicitly needed here and is more expensive than archive.
- C. Block storage is typically used for operating systems and databases requiring low-latency, high-performance access, and is not suitable for cost-effective storage of infrequently accessed logs.
Archive Object Storage
A storage class optimized for extremely infrequent access and long-term data retention, offering the lowest storage costs but with higher retrieval costs and longer retrieval times.
- Ideal for compliance, regulatory, and disaster recovery archives.
- Retrieval times can be minutes to hours.
- Lowest cost per GB stored.
Memory trick: Archive storage is like putting old files in a deep, cheap, but slow-to-access vault.
