Difficulty: MediumAzure Storage Accounts, Blob, Disk, Files, and Storage Tiers

A company is developing a public-facing website that hosts software installation packages for customer download. The packages are updated frequently, and customers download them continuously throughout the day. The website must retrieve these files directly using standard HTTP/HTTPS protocols.

Which Azure Storage service and access tier should you recommend to meet these requirements?

  1. A
    Azure Blob Storage configured with the Archive access tier
  2. B
    Azure Disk Storage configured with the Hot access tier
  3. Azure Blob Storage configured with the Hot access tierAnswer
  4. D
    Azure Files configured with the Cool access tier

Answer

Azure Blob Storage configured with the Hot access tier
The option recommending Azure Blob Storage with the Hot access tier is correct because Blob Storage is designed for hosting unstructured data like installation files and supports direct HTTP/HTTPS access. The Hot tier is optimized for data that is accessed frequently, making it the most cost-effective and lowest latency choice for continuous customer downloads.

Step-by-Step Solution

1
Analyze the access method and protocol requirements.
The files must be accessible directly via standard HTTP/HTTPS protocols for public downloads.
This helps filter out storage services that require specific network protocols (like SMB/NFS) or VM attachments.
2
Evaluate the storage services based on access method.
Azure Disk Storage requires attachment to a VM (IaaS block storage) and cannot be accessed via direct HTTP/HTTPS. Azure Files is designed for SMB/NFS file shares. Azure Blob Storage natively supports direct HTTP/HTTPS access for unstructured data.
This identifies Azure Blob Storage as the correct service type.
3
Determine the appropriate access tier based on the access frequency.
Since the packages are downloaded continuously throughout the day, the Hot access tier is required to avoid latency and high transaction charges. The Archive tier is offline and requires rehydration, making it unsuitable for immediate, frequent access.
This selects the Hot tier over Archive or Cool tiers to optimize for high access frequency.
