We have built a data and analytics platform in AWS cloud which will provide you as much computational power as you will need. We also have a Gurobi cloud license for solving some optimization problems. Our data is flowing real-time to a data warehouse in Snowflake. We already have multiple machine learning models in production and our optimization results are already being used in several cases related to work shift planning and operating trains.
