Anaplan itself doesn't have any API for pushing data to another platform. As @kavinkumar noted, you can install Anaplan Connect on AWS to run scripts that extract data from your model(s) to store on AWS. Alternatively, there are a number of ETL tools with connectors to AWS and Anaplan (as well as a number of other sources). Using this method would save you having another set of scripts to maintain, if you're already using Anaplan Connect, in addition to the other benefits afforded by ETL tools.
