Developing large-scale data mining, simulation and optimization software for the past decade, we have worked extensively with Amazon EC2 and other cloud services since their inception. In short, we launched Bidelastic as cloud users who saw an opportunity to make it more effective for others to use cloud computing. Our solutions have been developed in cooperation with researchers affiliated with the Warsaw School of Economics and Columbia University. Rest assured, the math in our solutions is solid.
