Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsMedium
A global pharmaceutical company is designing a new research data analytics platform in Azure. The platform will process extremely large datasets (petabytes) of genomic and molecular data, requiring high-throughput, low-latency access for complex analytical queries. Data scientists need to perform interactive analysis directly on this data. The solution must also support hierarchical namespaces for organizing research projects and strict access control. Which Azure storage solution is most appropriate for this scenario?
- AAzure Data Lake Storage Gen2
- BAzure Files Premium
- CAzure Blob Storage (Standard performance tier)
- DAzure SQL Database
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Data Lake Storage Gen2
Azure Data Lake Storage Gen2 is specifically designed for big data analytics workloads, offering petabyte-scale storage with high throughput and low latency. Its hierarchical namespace and integration with analytics services make it ideal for the described scenario.
Why the other options are wrong
- B. Azure Files Premium offers high-performance file shares but is typically used for SMB/NFS access to structured or semi-structured data, not for petabyte-scale big data analytics.
- C. Azure Blob Storage (Standard) is object storage, but the standard tier may not offer the required performance for interactive petabyte-scale analytics and lacks a hierarchical namespace.
- D. Azure SQL Database is a relational database service, not designed for storing and interactively querying petabytes of unstructured or semi-structured genomic and molecular data.
Azure Data Lake Storage Gen2
A highly scalable and secure data lake solution built on Azure Blob Storage, optimized for big data analytics workloads.
- Combines benefits of Blob Storage (scale, cost) with Data Lake Store (hierarchical namespace, POSIX permissions).
- Designed for petabyte-scale data with high throughput and low latency.
- Integrates deeply with Azure analytics services like Azure Synapse Analytics and Azure Databricks.
Memory trick: Data Lake Gen2: The 'Gen'ius '2' handle all your big data needs, like a giant, organized lake.
