The announcement was timed so that attendees at the 26th annual Forum of Incident Response and Security Teams (FIRST conference) in Boston could drop by Microsoft's booth for a demo and discussion. Right now Interflow private preview is available as a cloud service, but Microsoft is taking "input from early adopters in order to evaluate the need for an on-premises version."
How much does it cost? Microsoft's answer:
During the private preview Interflow is free for Microsoft Azure subscribers. Users need an Azure subscription for compute and storage resources, and can get started with an Azure trial subscription at http://azure.microsoft.com/en-us/pricing/free-trial/. During the private preview, there is no fee for the data feeds Microsoft is bringing to Interflow.
