Tesla's entire financial and operational system is completely internally-generated and integrated via its ERP software they developed in-house called Warp.
Warp enables real-time, collaborative, and synced operations for a seamless workflow across Tesla production and staff functions. It uses several technologies including:
AngularJS, Node.js, Redis Cache, Socket.io (for the dashboard), AWS SNS (for datapoint notifications), AWS Lambda (for some system automation tasks) and others.
