A multinational enterprise wants to migrate its on-premises data warehouse, containing several terabytes of structured data, to Azure. The new solution must support complex analytical queries, integrate with existing business intelligence (BI) tools, and offer elastic scalability to handle fluctuating query workloads from thousands of users. Which Azure data storage solution is most suitable for this scenario?
- AAzure Data Lake Storage Gen2
- BAzure Synapse Analytics
- CAzure SQL Database
- DAzure Database for MariaDB
Show answer & explanationAnswer & explanation
Correct answer: B. Azure Synapse Analytics
Azure Synapse Analytics is a unified analytics platform that combines data warehousing capabilities with big data analytics. Its dedicated SQL pool (formerly SQL Data Warehouse) is specifically designed for complex analytical queries on terabytes of structured data, offers elastic scalability, and integrates well with BI tools, making it ideal for migrating traditional data warehouses.
Why the other options are wrong
- A. Azure Data Lake Storage Gen2 is primarily for storing raw big data, not a complete data warehousing solution that offers the query engine and BI integration of Synapse Analytics.
- C. Azure SQL Database is a relational database, but it's generally for OLTP (Online Transaction Processing) workloads and not designed for the massive scale and complex analytical queries of a data warehouse like Synapse Analytics.
- D. Azure Database for MariaDB is a relational database for transactional workloads, not optimized for petabyte-scale data warehousing and complex analytical queries with elastic scalability.
Azure Synapse Analytics (Dedicated SQL Pool)
A cloud-based enterprise data warehouse that leverages a massively parallel processing (MPP) architecture to run complex queries across petabytes of data, offering elastic scalability and integration with other analytics services.
- Separates compute from storage for independent scaling
- Optimized for analytical workloads (OLAP)
- Integrates with Power BI and other analytics tools
