For about two months, we’ve been working on a static website that exposes the results of complicated economics model to non-economists. We decided to make the site static because of the overhead involved in computing the results and the proprietary nature of the model. We would simply pre-generate the output for all valid permutations of the inputs. However, on a single machine, we found it would take 30 hours of uninterrupted processing! Clearly, this was a job for “the cloud”.
