Niko Neugebauer gives into Azure Elastic Jobs, now generally available:
They key feature that needs to be well understood and which points to the potential of the Elastic Job Agent is that you are in no way limited by your own Azure SQL Database, nor by the logical Azure SQL Server where this database is located (contrary to the MSDB Database on the SQL Server), nor will you be limted by the Azure Region, Azure Resource Group or even Azure Subscription – you can configure the Elastic Job that will be reaching out to potentially any Azure SQL Database (given the necessary settings & permissions are correctly configured).
Read the whole thing. Niko shares some interesting thoughts on how it works, how you can tie your one server to a whole host of SQL Databases, and a wish list on what should come next.
