Arun Sirpal shows how to unpause an Azure SQL Data Warehouse instance using Powershell:
I totally forgot that with Azure SQL DWH you can pause and resume compute, to save money because it is expensive. Question is how do you go about resuming compute? TSQL is not possible and sure you can do the change via Azure portal but what about PowerShell?
This makes it easy to script out an overnight data load and then pausing the Azure Data Warehouse until the morning when those analysts come in, so that you can save a bit of cash (or a lot, depending upon your DWU utilization).
