The Jet Configuration Service is part of the Jet Service Tier which is capable of being installed on a wide variety of SQL databases and Operating systems - including SQL Server 2012 and 2012 R2.
Azure SQL - while *similar* to SQL Server 2012 - is *not identical* to SQL Server 2012 and is not directly compatible with all versions of the installer for the Service Tier.
However, it is still possible for an Azure administrator to configure the Azure portal to be able to install the Service Tier
The Jet Service Tier installation files are included with the installation files for Jet Reports.
For those Service Tier installations requiring special Azure configuration steps, specific instructions for installing on Azure are also included.
Please refer to the READ_ME_FIRST.TXT file located in the Azure configuration files folder for instructions on configuring the Azure portal.
