Storage Services at a Glance¶
Azure Storage provides several services tailored to specific data types and access requirements. Selecting the right service is critical for performance and cost optimization.
Service Comparison¶
| Service | Data Type | Protocol | Use Case |
|---|---|---|---|
| Blob | Unstructured | REST | Images, documents, streaming |
| Files | File Shares | SMB/NFS | Lift-and-shift, app config |
| Queue | Messages | REST | Decoupling services, task lists |
| Table | NoSQL | REST | Structured data, key-value |
| Blob Storage with Data Lake Storage Gen2 | Hierarchical namespace | REST (Hadoop-compatible via ABFS) | Big data, analytics |
Service Selection Decision¶

Note
Choosing the right service ensures optimal latency and throughput. For instance, use Queue Storage for high-volume asynchronous messaging rather than using a database table.
Selection Reminders¶
- Match service choice to access pattern first, then optimize cost.
- Validate protocol requirements (REST, SMB, NFS (Data Lake Gen2 uses dfs endpoint with Hadoop-compatible ABFS)) early.
- Confirm lifecycle and retention requirements before deployment.
