real time stock tickers what's the best architecture

hey everyone, im working on a system that needs to display real-time stock price updates to thousands of concurrent users. We're thinking about using WebSockets for the main connection, but im wondering about the best way to handle the backend. Should we have a separate service that subscribes to a market data feed and then fans out updates via WebSockets? Or are there other patterns for high-throughput, low-latency real-time data distribution that we should check out? Curious to hear about your experiences with similar systems.
