""I thought I'd just spend a little bit of time talking about how now Azure is even better [than Redshift]," he said, first focusing on the fact that a user can independently adjust the amount of compute and storage that you use with SQL Data Warehouse, as opposed to the fixed ratio required by Redshift. "This allows you to reduce costs and pay only for what you actually need," he noted.

SQL Data Warehouse, he said, will allow you to automatically scale up your data warehouse "in seconds." Not so with Redshift, Guthrie claimed, dissing AWS's service because "typically it takes hours or even days to rescale your data warehouse, and your data warehouse goes into a read-only mode with [performance] degradation.""
