WRONG ANSWER : Azure HDInsight
Azure HDInsight is a managed, full-spectrum, open-source analytics service for enterprises. HDInsight is a cloud service that makes it easy, fast, and cost-effective to process massive amounts of data. HDInsight also supports a broad range of scenarios, like extract, transform, and load (ETL); data warehousing; machine learning; and IoT. HDInsight requires a cluster shutdown to resize.
RIGHT ANSWER: Azure SQL Data Warehouse
Azure SQL Data Warehouses are a cloud-based service that leverages massively parallel processing (MPP) to quickly run complex queries across petabytes of data in a relational database
Hi Oliver, I think the answer lies in the last part of the question "……gaining insights with data with easy scaling." AZURE HDInsight cannot resize with out shutdown, (although the documentation now reads that there is no need to shutdown just to stop processing). The scalling for AZURE HDInsight does not appear to be automatic, where it is atleast an option for the other two sollutions. So it’s the easy scaling that disqualifies AZURE HDInsight.
