Azure Data Lake Analytics
is a distributed analytics service built on Apache YARN that dynamically scales so you can focus on your business goals, not on a distributed infrastructure. Instead of deploying, configuring, and tuning hardware, you write queries to transform your data and help extract valuable insights. This analytics service can handle jobs of any scale instantly by simply setting the dial for how much power you need. You pay for your job only when it is running, making Data Lake Analytics cost effective. Data Lake Analytics supports Azure Active Directory so you can integrate access and roles with your on-premises identity system. It also includes U-SQL, a language that unifies the benefits of SQL with the expressive power of user code. U-SQL’s scalable, distributed runtime lets you analyze data more efficiently in the store and across SQL Server in Azure, Azure SQL Database, and Azure SQL Data Warehouse.
