# Environment & Infrastructure

> What runs Ziplime's US environment

Ziplime runs on **AWS infrastructure**. Supported instruments are **ETFs and stocks**, with historical data going back to 2005 and a 15-minute market data delay.

Live trading connects to the broker **Lime Trading** ([lime.co](https://lime.co)) through **Lime Trader (REST API)** — see [Real Trading](/guide/platform/real-trading) for how that connection works.
