A paper was released today which outlines some scenarios for combining SSIS with StreamInsight. In essence, they are trying to show the value of using a streaming, time-oriented engine alongside a data transformation and quality engine.
They specifically call out two patterns: embedding StreamInsight within SSIS and embedding SSIS within StreamInsight. The background discussion is a bit light and some points are covered only in passing. I would have liked to have seen more about how you decide to use which specific pattern.
That said, the biggest value of this paper for me was reading through a few of the scenarios (in a telecommunications setting) and seeing examples of WHY you would combine these technologies. Reading this paper may get your mind thinking about use cases for your own organization.
