Microsoft Azure Data FundamentalsDescribe an analytics workload on AzureMedium
A media streaming company generates petabytes of log data daily from user interactions, device telemetry, and content consumption. They need to store this data cost-effectively for long-term retention (several years) and occasional historical analysis, without requiring immediate, high-performance access. Which Azure storage tier is most appropriate for this scenario?
- AHot tier
- BPremium tier
- CCool tier
- DArchive tier
Show answer & explanationAnswer & explanation
Correct answer: D. Archive tier
The Azure Blob Storage Archive tier offers the lowest storage cost for data that is rarely accessed, with flexible latency requirements (hours). This aligns perfectly with the need for long-term, cost-effective retention of rarely accessed log data.
Why the other options are wrong
- A. Hot tier is for frequently accessed data with highest storage cost.
- B. Premium tier is for high-performance, low-latency workloads, not cost-effective long-term archival.
- C. Cool tier is for infrequently accessed data with lower storage cost than Hot, but higher than Archive.
Azure Blob Storage Archive Tier
The lowest-cost storage tier for Azure Blob Storage, optimized for rarely accessed, long-term data retention with flexible latency requirements.
- Lowest storage cost, highest access cost and retrieval latency.
- Suitable for data that can tolerate several hours of retrieval time.
- Ideal for backups, archival, and compliance data.
