Design low-latency trading infrastructure
System Design: Low-Latency Trading Infrastructure
You are tasked with designing the end-to-end infrastructure for an electronic trading system. This system operates under strict latency and correctness requirements.
The core setup involves two distinct geographical locations:
- A colocated server/locker box positioned directly next to the exchange, ensuring extremely low latency access to market data and order execution.
- An office location in a different city, where traders operate, introducing higher latency due to Wide Area Network (WAN) communication.
Prompt
Design the complete infrastructure required to support the following functionalities:
- Receiving real-time market data.
- Generating automated trading decisions.
- Managing trading risk.
- Sending orders to the exchange.
- Monitoring and controlling the entire system.
Your design discussion should explicitly cover:
- The distribution of components and services between the colocated box and the remote office.
- Networking considerations, including physical links, redundancy strategies, and the trade-offs between bandwidth and latency.
- Protocol choices, specifically comparing TCP/IP and UDP, and addressing concerns like packet loss, ordering, and jitter.
- Server hardware considerations, precise time synchronization mechanisms, observability tools, and overall operational safety measures.
Assume extreme sensitivity to both latency and correctness throughout your design.

Core dilemma
Balancing extreme low-latency requirements for critical trading operations (market data, order execution, decision making) with the need for robust correctness, comprehensive risk management, and operational observability across a geographically distributed, high-performance environment.
