My primary use of this solution is for mathematical models that we develop and buy. The mathematical models are being bought from companies like Siemens, General Electric, SMS, and DMAC Group. Primarily these companies give us this software, we buy it from them, they make mathematical models for steel plants and we also make our own models.
I also have around 40 portals that I'm running on that I had developed and maintained. I use the DL servers to host the databases and the portal.
