Microsoft Certified: Azure Solutions Architect ExpertDesign data storage solutionsMedium
A media company streams video-on-demand content globally. They need to store petabytes of video files, which are accessed frequently for a few weeks after release, then less frequently, and eventually rarely. The company requires a cost-effective solution that allows for hot access to new content and gradually moves older content to cheaper storage tiers with minimal manual intervention. Which Azure storage solution and feature combination should be recommended?
- AAzure Data Lake Storage Gen2 with HDFS ACLs
- BAzure Files with Azure File Sync
- CAzure Disk Storage with Snapshots
- DAzure Blob Storage with Lifecycle Management
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Blob Storage with Lifecycle Management
Azure Blob Storage is ideal for storing large amounts of unstructured data like video files. Lifecycle Management policies can automate the transition of blobs between hot, cool, and archive tiers based on age or access patterns, optimizing costs while ensuring accessibility.
Why the other options are wrong
- A. Azure Data Lake Storage Gen2 is for big data analytics, not specifically designed for streaming video content with automated tiering based on access patterns.
- B. Azure Files is for shared file access and SMB/NFS protocols, not optimized for petabyte-scale video streaming with tiering.
- C. Azure Disk Storage is for virtual machine disks and does not offer built-in, automated tiering for large object storage like video files.
Azure Blob Storage Lifecycle Management
A feature of Azure Blob Storage that allows you to automate the process of tiering blobs to a more cost-effective access tier or expiring them after a specific time period.
- Rules can be based on age, last modified time, or access time.
- Supports moving blobs between Hot, Cool, and Archive tiers.
- Helps optimize storage costs and manage data retention policies.
Memory trick: Blobs manage their life, saving cash on the fly.
